21.4 degrees on the Pilatus: It has never been so warm in September ++ more records broken in the mountains

Heavy thunderstorms, hail, snow or heat: In this news blog you will find everything about the weather in Switzerland.


More records broken

It is exceptionally warm in the mountains. After a new record was already measured on the Pilatus at noon, MeteoNews also reported a new temperature record for the Bernina Pass in the afternoon. It recorded a new high: 20.8 degrees (previously 20 degrees in 1987). Of all the mountain stations recorded, the Graubünden Munt Buffalora (1973 m above sea level) was the warmest at 23.5 degrees. The previous temperature record from 1982 was one degree cooler. (zfo)

21.4 degrees were measured today on Mount Pilatus, which is 2 degrees above the previous September high of September 14, 1987! There were also new records on the Grimsel and at other measuring stations. The continuously updated list is available at 👉 https://t.co/Su3HZIj0h9 (rv) pic.twitter.com/66hcQW5xTg

21.4 degrees on the Pilatus: it has never been so hot in September

“MeteoSwiss” measured a temperature record for September on Mount Pilatus. At 2 p.m. it was 21.4 degrees warm, hotter than ever in September. This exceeded the September record of September 14, 1987 by 2.0 degrees. The reason for this is a strong high that lies over large parts of Europe. The high pressure area is flanked by two low pressure areas: one west of Portugal, the other over the eastern Mediterranean. A stable Omega weather pattern has thus been established, which will bring stable, very warm and sunny weather throughout the week. Since the high is very strong and its core is just north of Switzerland, the temperatures are exceptionally high, especially in the middle elevations. (rem)

1:42 p.m Monday, September 4th

At least 20.8 degrees: New September record also on the Grimsel

Summer day on the Grimsel? At 1 p.m., “MeteoSwiss” measured 20.8 degrees at the transition between the cantons of Bern and Valais. This is a new record for this season. The last time it was similarly warm was September 4th, 1973 at the Grimsel with 20.0 degrees.

50th “anniversary” at the measuring station #Grimsel Hospitz (1980 m above sea level): On September 4, 1973, the highest temperature so far was 20.0 degrees at this station #Temperature measured in September. Today, this value was surpassed for the first time in September with 20.8 degrees (as of 1 p.m.). pic.twitter.com/o9hjDVQ1NP

— MeteoSchweiz (@meteoschweiz) September 4, 2023

The measuring station at the Grimsel is 1980 meters above sea level. Because the temperatures are traditionally only highest in the middle of the afternoon, the new record value should end up being even higher.

In meteorological and climatological terms, a summer day is considered to be when the maximum temperature reaches or exceeds 25 degrees. (sat)

11:46 a.m Monday, September 4th

21 degrees in the morning: How high will the new September record be on Pilatus?

The omega high pushes through. For example on Pilate. On Monday, at 10 a.m., 20.2 degrees were already measured on Lucerne’s local mountain, as “MeteoNews” on X (formerly Twitter) writes.

here at #Pilatus September 14th, 1987 was the warmest September day with 19.4 degrees. That has now been settled, because we are already measuring 20.2 degrees! The end of the road has not yet been reached, and other mountain records are also shaky. Measurements=> https://t.co/2lv0pkxXAz (km) pic.twitter.com/6dza9ugdSA

As “MeteoNews” explains, the previous September record on Pilatus was 19.4 degrees and dated September 14, 1987.

And the warmest period of the day is far from over. Like the weathermen in hers Weather blog write, the temperature at 11 a.m. on Mount Pilatus was already 21 degrees.

It is quite possible that other mountain temperature records will also tumble on Monday. “We haven’t reached the end of the road yet,” say the weathermen. (sat)

Start of the week with summer weather in autumn and the second highest zero level

Almost another record value at the zero degree limit: on Monday night, the freezing point over Switzerland climbed to 5253 meters above sea level. This is the second highest value since measurements began in Payerne (VD) with balloon soundings, as MeteoSwiss writes on X (formerly Twitter):

Only 14 days after the new record, today, Monday, September 4th, 2023, there was another very high one #freezing line above the #Switzerland measured. In the radiosonde ascent from Payerne, this was at 00 UTC at 5253 m above sea level. M. This is the second highest value since measurements began in 1954. pic.twitter.com/VFLUptIEPw

— MeteoSchweiz (@meteoschweiz) September 4, 2023

This value is only 45 meters below the new record set two weeks ago. At that time, the zero-degree limit in Switzerland climbed to 5,298 meters above sea level.

But it is also clear that the freezing point over Switzerland climbed over 5000 meters above sea level for the first time in September or outside of midsummer, as Kachelmannwetter.com writes on X on Monday. And according to “MeteoSwiss”, the zero-degree limit should also be based on the 5000-meter mark in the coming days.

Since 1954, MeteoSwiss has raised a measuring balloon twice a day near Payerne – now fully automatically.

Too warm, too wet and too cloudy: That was August 2023

Now it is definitely certain: the past month was “1.5 degrees too warm, a bit too wet and slightly too cloudy”, as MeteoNews published on Friday Weather blog holds.

Compared to the long-term mean temperatures (years 1991 to 2020), August 2023 is in the top 10. According to MeteoNews, however, it does not quite come close to the warmest Augusts in 2003, 2022 and 1992.

The graph from MeteoNews shows where the temperature in Switzerland deviated particularly strongly last August:

Even if that may sound a bit surprising: The last days of the month with heavy precipitation led to a total of 20 percent wet August (according to MeteoNews on X) at the end of the month despite the heat wave.

On the other hand, the amount of sunshine in August – viewed across the whole country – was just 7 percent below the long-term average. It was slightly below average in many places in the north, while there was a small surplus in the south (despite extremely heavy rainfall towards the end of the month). (sat)

06:29 a.m Friday September 1st

Summer returns again

Friday marks the beginning of meteorological autumn. Until the third season begins astronomically, it will take until September 23 at 8:49 a.m. Only then is the day and night equinox or the sun is vertically above the earth’s equator.

It doesn’t matter. After the past few rainy days, we’re taking the comeback of summer anyway.

As for example SRF Meteo on X (formerly Twitter), it is quite sunny on Friday during the day with temperatures up to 25 degrees:

#Friday weather: Summer comeback at the meteorological beginning of autumn. Fairly sunny during the day in the north, sun and cumulus clouds in the Alps and in the south. Highs around 25 degrees. pic.twitter.com/WfPaBGyCvy

— SRF Weather (@srfmeteo) September 1, 2023

And even at an altitude of 2,000 meters, the weather forecasters are still predicting a warm 16 degrees. In the coming days it should even get up to 27 degrees warm again.

And Kachelmannwetter.com also promises on Friday on the short message service: “This is the start of a sunny, warm late summer weather phase.”

The last weak rain showers (in the cantons & districts) are moving over the north and north-east of the #Switzerlandthen consists of the daytime #Alps out more and more sunnier #Wetter through – this is the start of a sunny and warm late summer weather phase.

— Alpine weather | kachelmannwetter.com (@Alpinwetter) September 1, 2023

Incidentally, the reason for the late summer temperatures is a “pronounced and very stable high pressure ridge over western Central Europe”, as MeteoNews writes in its weather blog.

And this omega high (as it’s called because of its shape) “shouldn’t budge for days.” In other words, don’t ask when it ends. Just get out and enjoy. (sat)

Situation in Schwanden: 38 properties are already affected

The authorities gave an update on the situation in Schwanden on Wednesday evening. Present at the media conference were Richard Schmidt, media spokesman for Kapo Glarus, Hans Rudolf Forrer, mayor, and Hanspeter Speich, chief of staff of the community leadership organization.

Various fire brigades were deployed on Wednesday, said Forrer. Exclusion zones have been expanded. “38 properties are already affected by the debris flow,” said the mayor of the damage. “We still have 66 emergency services on site, yesterday there were 100,” added Speich.

The heavy rains of the past few days have made the situation significantly worse, as geologist Markus Gächter explained at the media conference. “We have never seen so much water on site.” It is assumed that 30,000 cubic meters of material have been released in the landslides so far. Another 60,000 cubic meters could break out.

So far 97 people have been evacuated. There will be another media conference on Friday. (nic)


The situation in Schwanden remains critical

The Glarner authorities provide information at a media conference about the situation after the landslide in Schwanden. The situation is still critical. Debris flows continue to occur. More than a dozen houses are affected. The residents of the affected properties are currently being informed. All evacuated people are housed in hotels or other accommodation. Sometimes there are several meters of earth on the houses.

The water is still running. There is still a risk that the local river Sernf could be dammed by the slide and cause flooding. Authorities said there were still no injuries. How the situation will develop in the next few days is currently difficult to assess. (mg)

Many flood warnings are lifted

In many bodies of water, the levels are still very high. But the federal government can also give the all-clear for many bodies of water. There shouldn’t be a flood in many places. “The intensity of the precipitation has decreased significantly in all regions. This is the end of the warning event», it says in the natural hazards bulletin.

However, the warning cannot go away everywhere. “Regarding floods, the warnings for the Thur and the High Rhine as well as for Lake Zurich, Lake Walen and Lake Lucerne are still active,” says the website. All other flood warnings have been lifted. (mg)

Significant amount of rain in just 24 hours

In Urnäsch (AR) a total of 97 mm of rain fell between Monday and Tuesday. It also rained a lot in other communities in eastern Switzerland. In St.Gallen, for example, 85 millimeters were measured. For comparison: Normally, the rain total for the whole of August in the city is 185 mm. This is reported by the weather service MeteoNews.

“Looking at the entire precipitation period of the last three days, Biasca remains by far in first place with 386 mm within just under 72 hours,” says the website. That is more than twice as much as usual in a normal August total.

It will remain rainy on Tuesday. the same high amounts of rain are no longer expected. (mg)

Snowfall leads to relaxation on the flood front

With the temperatures, the snow line has also dropped significantly. Like here at the Rugghubelhütte above Engelberg:

At almost 2300 meters it is already very wintry.

At almost 2300 meters it is already very wintry.


The snow is also good news for the situation on the flood front. Since the water remains as snow and does not immediately reach the valley, this leads to a slight relaxation in the water levels, as a meteorologist at Radio SRF explained. The snow line rises on Tuesday in the west from around 2000 to 2300 meters, in the east from around 1700 meters to a good 2000 meters, as “SRF Meteo” writes.

The heavy rains in southern Switzerland are causing more and more problems. Since Monday morning, the city of Bellinzona has also been calling for the drinking water in two parts of the community to no longer be used. The towns of Moleno and Preonzo are affected by the measure. There, the drinking water may not be used for drinking, cooking or washing until further notice, according to reports from the warning platform AlertSwiss emerges.

The drinking water in large parts of the Maggia Valley has also been contaminated since Sunday. As the authorities write on AlertSwiss, this can – if clear – still be used after boiling for five minutes. The municipality of Bodio in the Leventina already issued the same precautionary measures for drinking water on Saturday.

Is today the last hot day of the year in Switzerland?

After the thunderstorm is before the next thunderstorm. In between, however, Friday promises to be hot again. Perhaps “one last time”, as “MeteoSwiss” writes on X, for example:

This Friday, quite sunny during the day, but thunderstorms, locally already in the morning downpours and #Thunderstorm. One last time hot with around 30 degrees in the north and 33 degrees in the south! The weekend falls into the water 👉 https://t.co/2HbU97BwMO (rv) pic.twitter.com/ycWUTSVvGo

Thunderstorm with 100,000 lightning bolts and heavy gusts

The last thunderstorms passed shortly after midnight. What remains is the balance of the stormy night. As SRF Meteo writes on X (formerly Twitter), the thunderstorms in Switzerland brought a total of around 52,000 lightning bolts on Thursday evening and Friday night:

Not only yesterday evening, also during the night it stayed on the northern edge of the #Switzerland #thundery.

But the emergency services were also in demand on Thursday evening in the Bernese Oberland and in Valais. Occasionally streams burst their banks. As a result of the storm, the main road in the Lötschental was also flooded. She is still blocked. (sat)


Zurich Open Air is evacuated

Due to the heavy thunderstorm, the Zurich Open Air is evacuated. HowWatsonreported, people are currently being banned from the premises. “It’s absolute chaos here,” says one visitor. A security employee asked people: “Everyone go on, this is not a game.” All visitors have to leave the site, chaos reigns.

Meanwhile, the Zurich Openair writes on Instagram that the concerts have been interrupted for security reasons. Guests are requested to leave the premises via the main entrance. After that, you should follow the instructions of the security and the police. “Your safety is our top priority,” said the organizers. More information would follow.

39.3 degrees in Geneva: It has never been hotter in 2023

The heat wave is at its peak. 38 degrees were measured in Geneva today at 2 p.m. This is the highest temperature measured in Switzerland in 2023, as SRF Meteo writes on the short message service “X”. According to the official weather service of the federal government Meteo Schweiz, it is still a bit warmer – also – in Geneva. According to this, the thermometer even rose to 39.3 degrees. It is still possible that it will get even warmer.

In #Geneva 38 degrees were already measured at 2:00 p.m. today. This is the highest measured in Switzerland #Temperature in 2023. Let’s see what the day brings. #SweatSweat 🥵️^rb pic.twitter.com/vma3vJCepa

By the way, the value is only slightly below the absolute record mark. In 2015, 39.7 degrees were measured in Geneva. The highest value in Switzerland north of the Alps.

06:54 a.m Thursday, August 24th

Forecast for Thursday: up to 38 degrees!

Already on Wednesday the thermometer climbed to record levels (or at least close to it) in many places in Switzerland. In Geneva, for example, 36.7 degrees were measured, the previous maximum value was 36.2. In Disentis, the absolute record value for the whole of August was measured at 32.8 degrees.

According to the latest weather forecasts, further records could tumble for the last time on Thursday (before local thunderstorms, some of them violent, should dampen the heat wave that has been going on for days by about ten degrees once and for all towards the evening).

While SRF Meteo is still announcing comparatively “low” temperatures of “32 to 37 degrees” for Thursday on X …

For comparison: The Swiss temperature record is 41.5 degrees. This was measured on August 11, 2003 in Grono (GR) at 382 meters above sea level. In Europe, the record value is 48 degrees – measured on July 10, 1977 in Athens. The world record is 56.7 degrees in California – measured on July 10, 1913, as MeteoSwiss on its Website writes.

Conclusion: Before the end of the heat wave is approaching, there are still a few hours left to visit the dream pool, the cozy river pool or your favorite bathing beach one last time. Then it’s autumn…(sat)

Another absolute fire ban in the canton of Valais

The dry and hot weather of the last few days has significantly increased the risk of forest fires in Switzerland. The canton of Valais has therefore taken measures: Since Tuesday evening, there has been an absolute ban on fires in the open air throughout the canton. Such a fire was already proclaimed this summer, but only after the outbreak of the forest fire near Bitsch. That had led to criticism.

The responsible write in a message: “Based on the weather forecast, no major precipitation is expected for the next few days and temperatures, especially at night, are likely to remain at a high level. As a result, the general risk of fire in Valais reaches a very high level, especially in forests, meadows, scrub, fallow land and so on.”

The risk of forest fires is also high outside of the canton of Valais. Measures are therefore also in force in some regions, as our map shows. (rus)

06:06 a.m Wednesday 23 August

The temperature records tumble in rows

The current heat wave is causing numerous temperature records. As MeteoSwiss writes on the short message service “X”, record values ​​​​were measured at many stations for the second half of August. The thermometer in Geneva climbed to 36.7 degrees, the previous maximum value was 36.2. In Disentis, the absolute record value for the whole of August was measured at 32.8 degrees.

Switzerland also sweated at night

Even during the night there was no real cooling in many places. As the weather service MeteoNews writes on the short message service “X”, there was a widespread tropical night in Switzerland.

1:43 p.m Montag, 21. August

When will the current heat wave end? One thing is clear: Thursday at the earliest

According to the vernacular, it has long been clear when the current heat wave will end: on Wednesday. Because that is when the so-called dog days, as the traditionally hottest days of the year between July 23rd and August 23rd are called, end.

What the weather thinks of the dog days rule is not known. But the current forecasts actually predict that the current, extremely stable anticyclone over central, southern and parts of western Europe should dissipate towards the end of the week. However, it is still unclear how quickly.

With a south-westerly current, “very warm and humid, but also unstable, stratified air” should still reach us, as “MeteoSwiss” puts it in his Weather blog writes.

A change in the weather is on the horizon: from the weekend it should be a good ten degrees cooler and wet in Switzerland.

According to MeteoSwiss, at least the probability of thunderstorms (and thus cooling) will increase significantly from Friday. Or in the words of «MeteoNews»: “The trend shows that temperatures between around 19 and 24 degrees can be expected from Sunday and the heat wave will thus come to an end.”

However, SRF Meteo already reported last week that there are signs of a change in the weather. According to a post on “X”, up to 15 millimeters of rain are possible, especially on Friday:

Confederation partially imposes heat warning level “red”

Due to the ongoing heat wave, the federal government is increasing its heat warnings for certain parts of Switzerland. The heat warning level “red” and thus “very high risk” has been in effect since Sunday in the Lake Geneva region and in Ticino.

The third highest level “orange” (and thus “considerable danger”) continues to apply in large parts of Switzerland, namely in the Mittelland, the Pre-Alps and Valais. The current federal heat warning is valid until Thursday.


In addition, the federal government continues to warn of a “great” to “very great” risk of forest fires throughout Valais and the western Jura arc. There is also a “considerable risk” of forest fires in the central plateau and in parts of Graubünden. (sat)

Switzerland remains in a headlock. That’s why the weather forecast for the start of the week is also quickly told: “Sunny and muggy,” writes MeteoSwiss on its website. “Harmless cumulus clouds” are also possible over the mountains in the afternoon.

The only change from the last few days: the thermometer should “only” reach a maximum of 34 degrees on Monday. A few points lower than last.

Or as SRF Meteo puts it on “X”, the former short message service Twitter: “It’s pretty sunny every day and in the second half of the day there are sometimes heavy thunderstorms over the mountains.”

That holds true today and in the coming days #schwülheiss|e #summerweather at.

But towards the weekend, the summer will then “just in time for the end of the dog days” (as the traditionally hot summer days between July 23rd and August 23rd are also called) turn up another level, like MeteoNews on the ex-Twitter service writes:

Midsummer is coming back this week. Just in time for the end of the dog days, well over 30 degrees are forecast at the weekend, and the 35 degree mark will be cracked in places. More about the timetable and thunderstorms -> https://t.co/gVsmfM9CcT (me) pic.twitter.com/8Qkoy4uM1z

A high pressure area over Central Europe will ensure “a whole series of midsummer and muggy days”, the weathermen from MeteoNews explain in their MondayWeather blog.

According to the forecast, it is likely to be particularly hot in parts of northwestern Switzerland, the Lake Geneva region and central Valais. The weather forecasters for Ticino are not making quite such heated forecasts.

The federal heat warning from Monday for the current week: There is currently only a risk in the Lake Geneva basin and in southern Switzerland.

The federal heat warning from Monday for the current week: There is currently only a risk in the Lake Geneva basin and in southern Switzerland.


Accordingly, the federal government has so far only issued a “yellow” heat warning (level 2 of 5, “moderate danger”) for the Lake Geneva basin. In Ticino, on the other hand, the level “orange” (3 out of 5) and thus “considerable danger” still applies this week up to and including the weekend.

Meanwhile, the map of Switzerland looks much more colorful when it comes to the risk of forest fires. There is a “high” to “considerable” drought here practically throughout Valais, the latter also in parts of the cantons of Geneva and Graubünden. Meanwhile, there is a “moderate” risk of forest fires in most other parts of the country.(sat)

The current forest fire risk situation in Switzerland: red (severe), orange (severe), yellow (moderate) or green (no or low risk).

It snowed in the mountains

In the night on Monday it snowed up to 2000 meters, as reported by the weather service Meteonews on “X” (formerly Twitter). A few centimeters of snow fell from 2000 meters, in the high Alps above 2500 meters sometimes even more than 20 centimeters. Several passes were therefore presented in white on Monday morning, such as the Oberalp Pass, as the webcams show.

The Oberalp Pass webcam showed snow-covered slopes on Monday.

The Oberalp Pass webcam showed snow-covered slopes on Monday.


The early snow is good for the glaciers. According to Meteonews, the fresh snow protects against the sun’s rays in the next few days due to the high “albedo” (brightness) and thus slows down the melting process.

After a rainy Sunday, it got a little cooler in many places in the lowlands. Around 20 degrees are expected on the north side of the Alps on Monday. In the course of the week, however, the temperatures will rise continuously and on Friday, according to Meteonews, the 30-degree mark should be cracked again in the Mittelland. (gb)

Summer will soon make its comeback

Sun-seekers and pool fans can look forward to summer with its very warm temperatures coming again. As the weather service MeteoNews writes, he will be making his comeback next week. “After a slow start, very warm air will reach us again from the south-west by the middle of the week. As a result, the temperatures are increasing, on Wednesday the temperature level is definitely midsummer again and suitable for bathing, »says the message.

After that, the swimming trunks and bikinis do not have to be restocked immediately: “Even in the medium term, it will remain summery and warm,” writes MeteoNews. However, it is difficult to make a concrete statement about the number of possible hot days with temperatures of 30 degrees and more. Before late summer begins in mid-August, midsummer is “highly likely” to return.(mg)

It’s going to be a wet federal holiday. The morning is rainy, the clouds only break up towards evening. Rain will remain possible, according to “SRF Meteo”. In the north you can still count on a fairly fresh 20 degrees for a summer month. The maximum daily temperature is therefore below average. The people of Ticino have it better, where the sun reaches 27 degrees.

On the night of Tuesday it was warm again, especially in the south and west, as “MeteoSwiss” reports. There were even isolated tropical nights (20 degrees and more). (pin)

Army helps with reconstruction in La Chaux-de-Fonds

After the devastating storm in La Chaux-de-Fonds last week, the clean-up work has begun. From August 2nd, the army will provide support, as the Defense Department (VBS) announced on Monday. 80 members of the army are deployed as part of a disaster relief operation.

The canton of Neuchâtel itself has requested the support of the army, it is said. Not all vital infrastructure has yet been secured and cleared. Apparently, the canton is worried about the upcoming return of people from vacation and the start of school. It is also said that the available funds for the evacuation have already been heavily used.

The focus is also on clearing school buildings and streets “to protect the population from possible falling debris”. The army’s deployment is expected to last until August 11th. (gb)

Around 4000 buildings damaged by storm

After the strong storm on Monday in La Chaux-de-Fonds, the authorities informed on Tuesday about the extent and the current status of the clean-up work. The situation is currently “under control,” said Grégory Duc from the fire and rescue service. However, around 30 households are still without electricity. There are also several people whose homes were badly damaged. They would have organized themselves privately until they could return.

The emergency services are now busy restoring the infrastructure, the focus is on the safety of the population. Authorities are reminding residents of La Chaux-de-Fonds to stay away from overhead power lines and into the forest. This is too dangerous due to the great damage. Forest engineer Pierre Alfter says: “As an initial evaluation has shown, 1,600 hectares of forest were damaged.” It could take several weeks before all forest paths are accessible again.

Certain roads in Neuchâtel are still closed. These closures cannot be lifted yet because there are still unsecured, damaged trees, explained Grégory Duc.

Jean-Michel Brunner, director of cantonal building insurance, estimates the damage caused by the storm at around 70 to 90 million francs. Around 4,000 buildings were damaged. (chi)

Clean-up work resumed after storm in La Chaux-de-Fonds

The Neuchâtel cantonal police reported a tornado or so-called “downburst” in La-Chaux-de-Fonds this morning. The cantonal police of NE later confirmed to the Keystone-SDA news agency that a tornado actually passed through the city and devastated it.

According to information from the news portal «ArcInfo» numerous people were injured and at least one person died. According to the NE cantonal police, a crane fell on the person.

Whether it is down gusts (#Downburst) or a tornado and whether the measured 217 km/h is plausible will be shown by further investigations, writes SRF Meteo in a tweet. (zfo)

Worker in the canton of Schwyz suffers from heat stroke and falls down

There was an accident at work in Altendorf in the canton of Schwyz on Monday. A 28-year-old man allegedly suffered heat stroke while working on a roof, as the cantonal police wrote in a statement. As a result, the man fell about three meters and seriously injured himself. He had to be taken to the hospital by ambulance. The incident happened after 4:15 p.m.(lga)

Orange turns red: the federal government raises the warning of severe weather

In the morning, Switzerland was still orange. After midday, however, the federal government increased the probability of severe storms to the highest red level (red hatched area) in large parts of the country.

This severe weather warning, which is now very high, applies above all in southern Valais and along the entire main Alpine ridge and for large parts of Graubünden (with the exception of the Engadin):

In southern Valais and along the main Alpine ridge to Graubünden, the highest severe weather warning applies on Tuesday.

It’s nice in the mountains

While it’s getting 32 to 36 degrees warm in the valley today, it’s worth taking a trip up. At 2000 meters above sea level, the temperature is a pleasant 22 degrees. There are tips for hikes on mountain peaks – alternatively you can also take the cable car our leisure portal Berg und Beiz. But be careful: Thunderstorms can form in the mountains during the day.

Instead of in the heights one also finds cooling in the interior of the earth, for example in the St. Beatus caves near Interlaken or in these places.

Despite the heat wave: no records will be broken on Tuesday

Of course: It’s going to be really hot today. The temperatures are climbing widely in the range of “close to 35 degrees and locally a little more”, as the weather service MeteoNews in its Blog writes. But: “But there will probably be nowhere enough for absolute July records,” as stated in the message from Tuesday.

For comparison: According to MeteoSwiss, the highest temperature ever registered in Switzerland by an official measuring station was 41.5 degrees. It was that hot on August 11, 2003 in Grono (GR). However, this southern Graubünden measuring station is now at the bottom of the valley, which is why the value would now be lower according to the federal weather forecasters.

Back to the current heat wave: According to MeteoNews, the values ​​in Vaduz and Sion are likely to come closest to the previous records. In Bern, around 33.5 to 34 degrees are expected today. The absolute maximum in July is 36.8 degrees. In Geneva it will be up to 37 degrees warm today, but the record there is 39.7 degrees.

“One cannot therefore speak of historic heat today, in the long term there is simply a very hot midsummer day,” summarizes MeteoNews. (mg/sat)

Cancer League warns: stay in the shadows

The Swiss Cancer League estimates that 3,100 people are diagnosed with melanoma every year in Switzerland and another 25,000 with white skin cancer. This also shows that it is important to “protect yourself effectively from UV rays”, as the Cancer League writes on Tuesday.

The best sun protection is the shade. “Particularly between 11 a.m. and 3 p.m. you should avoid direct sunlight,” the cancer league continues. Sunscreen should also be applied “regularly and in sufficient quantity” and the solarium should be avoided in any case – not even to “pre-tan” the skin. (mg)

Animal welfare warns: Grazing animals also suffer from the heat

The heat of these days is also affecting the wildlife. As the Swiss Animal Protection (STS) writes on Tuesday, grazing animals need cool stables in addition to sufficient water in the summertime.

“Ideally” should also be set up night pastures for cows, sheep and Co. and during the day “many shaded areas that are as natural as possible”. Where these are missing, the STS warns in a message that structural measures should be taken to ensure that there are enough sun-free spots on the pasture.

According to STS, cows generally like it cool (between 4 and 16 degrees). And: You can already experience heat stress at temperatures from 24 degrees. This threshold is 25 degrees for unshorn sheep and pigs and 28 degrees for chickens. (sat)

In many places there was another tropical night – that brings Tuesday

In many places in Switzerland, Tuesday is likely to be the warmest day of the year so far. After a sometimes turbulent start to the week on Monday, for example, SRF Meteo on Twitter predicts a lot of sun, up to 36 degrees and thunderstorms in some parts for the evening:

Today often seems the #Sonne. In the evening and in the night on Wednesday there are some strong ones #Thunderstorm with #squalls on. Before that it will be 32 to 36 degrees. In the Rhone Valley even 37 degrees are possible. ^poss pic.twitter.com/15K6nlAoiB

But that’s not all: As Kachelmannwetter.com wrote on Twitter on Monday, it may even be up to 39 degrees hot in the lower Rhone Valley – specifically in Sion – this Tuesday.

MeteoSwiss already has an identical one for practically the whole of Switzerland Severe weather warning issued. Except along the main Alpine ridge, where the probability of occurrence of the event is estimated to be lower, the orange level applies until Wednesday morning (and thus a “considerable danger” with a high probability of occurrence):

In Switzerland, the orange level will apply in the next 24 hours and thus a “considerable risk” of storms.

But last night was already tough in terms of heat. As MeteoNews wrote on Twitter on Monday, another tropical night was registered in many places. In other words: the thermometer didn’t fall below 20 degrees.

It was warmest last night in Vevey with a minimum of 23.2 degrees. Also on the podium: Lugano (22.7 degrees) and Locarno-Monti (22.3 degrees).

Heat trap car: TCS advises to cool down

It is currently hot in the apartments and outside. Suva and the Unia union are already warning that the heat is endangering workers. But that’s not all: It’s also getting particularly hot in cars these days.

As the TCS writes on Monday, 50 degrees can be measured in the “heat trap car” after just a few minutes and even up to 80 degrees after an hour. According to TCS, staying in the car becomes dangerous from 40 degrees.

The TCS tips against cars that are too hot

  • When cars are stationary sun protection filmsan effective tool. This allows the temperature to be reduced by up to 40 degrees.
  • Do not leave children and animals in the car. Because after a very short time it gets extremely hot in the vehicles these days.
  • Conversely, it is advisable to enter when boarding short ventilation. This is not least to protect against burns when sitting on heated seats.
  • Regular checking of oil and coolant levelscan protect the motor from overheating.

And then the TCS clears up several misjudgments. Contrary to popular belief that the color of the car has a major impact on the interior temperature, tests show that the difference is minimal in the end. Although dark cars heat up faster than light ones, the end temperature is only a few degrees higher.

And slightly open windows in stationary cars miss the hoped-for cooling effect. It’s different with moving cars: Then, logically, the cooling takes place within a short time. However, the difference between the air-conditioned inside and outside temperature should not exceed 6 degrees. Otherwise, the health risks such as colds increased, according to the TCS. (sat)

From a tropical night to a thunderstorm alarm clock: Switzerland stays in a headlock

The hottest day of the year so far was followed by a tropical night. But not in the Mittelland, as you might think. Thanks to thunderstorms – not least from the west along the Jura to northwestern Switzerland and the Basel region – temperatures there once again fell below 20 degrees on Monday night, as SRF Meteo writes on Twitter:

#tropical night: in the night to today it stayed very warm for a long time. In many places, however, the temperatures dropped below 20 degrees, also thanks to thunderstorms. In slightly elevated areas, however, it remained 20 degrees all night, for example in Rehetobel/AR with a low of 23 degrees. ^poss pic.twitter.com/aBOXaSG4HE

— SRF Weather (@srfmeteo) July 10, 2023

At slightly higher altitudes, on the other hand, it stayed warm last night. And so the weathermen from SRF report a tropical night for Rehetobel (AR), for example. In other words: the temperature there between 6 p.m. and 6 a.m. never fell below 20 degrees or, according to SRF, in this specific case even remained constantly above 23 degrees.

Until a few decades ago, tropical nights were a rare phenomenon in Switzerland, at most more widely known from Ticino. From a medical point of view, they are considered problematic because the human body – especially in older or weakened people – can no longer cool down sufficiently from the heat of the day.

And the current, first real heat wave of the year in Switzerland will continue this week: In the lowlands, SRF Meteo is still forecasting individual showers or even thunderstorms in the morning. But the sun should soon gain the upper hand – even if the risk of thunderstorms remains: it will remain muggy and hot at 29 to 33 degrees, so the conclusion.(sat)

US platform: Daily temperatures persistently above record

According to preliminary data from US scientists, the average global temperature has now been five days in a row above the previous record value from 2016. The hottest recorded day worldwide was Thursday (July 6) with 17.23 degrees. According to the “Climate Reanalyzer” platform, the average global temperature was also above 17 degrees on Monday, Tuesday, Wednesday and Friday.

The previous daily record from the University of Maine’s “Climate Reanalyzer” data, which dates back to 1979, was 16.92 degrees on August 13 and 14, 2016, and the value was reached again in July 2022.

Further records are quite possible in the next few weeks, explained Helge Gössling from the Alfred Wegener Institute (AWI) in Bremerhaven. In the course of the year, the highest values ​​are typically reached around the end of July, since that is when the large land masses in the northern hemisphere are particularly heated. “By then, the records of the last few days could still be surpassed.”

In general, it is not surprising if there are more and more high temperature records. “While global warming initially increased moderately from decade to decade, the speed of change has gradually increased,” said Gössling. New records are therefore to be expected more and more frequently. (dpa)

Are more tropical nights imminent?

Weekend heat days could lead to tropical nights. On tropical nights when the thermometer never falls below 20 degrees Celsius. So far, despite the heat phase in June in the German-speaking part of Switzerland, we haven’t had a tropical night. There were only four tropical nights in June on Lake Geneva. Grenchen recorded a tropical night in July.

Now the meteorologists are not expecting warmer nights in some places until Monday night and possibly also tropical nights in the cities. They are more common in the city than in the country. In the knowledge column Knellipedia we explain why there can be a cool night even after hot days, what thunderstorms contribute to cooling and why there are cool nights in the hot desert.(kn)

From Sunday: danger level 3 for all of Switzerland

The federal government has extended its heat warning: Danger level 3 – i.e. “considerable danger” – now applies from Saturday noon in northwestern Switzerland and from Sunday noon throughout Switzerland in the lowlands. The heat warning is valid until Tuesday evening.

The Federal Office for Meteorology and Climatology (MeteoSwiss) speaks of a “distinctive heat wave in the lowlands throughout Switzerland”. As the meteorologists report, temperatures in the lowlands will rise to 32 to 34 degrees from Saturday to Tuesday. There can also be 35 degrees locally.

Possible effects of the heat are a significant risk for circulatory problems and physical discomfort. The federal government therefore recommends drinking plenty and regularly. And: These should be as unsweetened drinks as possible.

The heat wave starts on Friday – peak on Sunday

Now the summer of 2023 is finally starting: The first heat wave of the year is rolling on the weekend. Friday already begins with lots of sun and temperatures of 28 to 30 degrees. According to the meteorologists from MeteoNews, there are even up to 32 degrees in the Rhone Valley.

There could be local downpours and thunderstorms – for example in Valais and northern Ticino. “Basically, however, most people can look forward to a nice and mild summer evening,” write the weathermen from MeteoNews in their Blog. It is currently still unclear how far the downpours and thunderstorms will make it to the east.

On Saturday we will continue to turn the heat screw: The day starts overcast and with the last showers. By the afternoon at the latest it should be sunny and hot again. The meteorologists predict that the 30-degree mark will be cracked across the board.

The summer reaches its preliminary peak on Sunday. In the afternoon there should be widespread 33 to 34 degrees. In the greater Geneva area and in the Rhone Valley, the meteorologists even expect 35 to almost 36 degrees. For everyone who is looking for more cooling off than jumping into the cool water: The zero degree limit rises to 4300 to 4500 meters.

Speaking of cooling: According to MeteoNews on Sunday, local heat thunderstorms are possible towards the evening, especially in the Jura and in the Alps. (abi)

However, no concrete statements can be made about the temperatures and duration of the heat.

The weather will remain mostly friendly and sunny until Thursday. However, there can be downpours and thunderstorms in between – this is particularly possible on Wednesday. From Friday, thanks to a high pressure ridge, “quite dry and increasingly hot air” will flow into Switzerland, as it is also said. This means that the likelihood of thunderstorms should only be “low”. (abi)

Thursday starts mostly sunny and the temperatures rise again to almost 30 degrees in midsummer. But in the afternoon clouds are gathering and it is becoming increasingly cloudy. MeteoSwiss initially expects a few showers and thunderstorms over the Alps. In the evening it will probably rain and thunder in the lowlands, as the weather service writes.

This is the start of a wet Friday. Depending on the region, there will be heavy showers and thunderstorms. Temperatures will still reach around 21 degrees. According to forecasts, the last rain is expected to fall on Saturday morning.

MeteoNews expects it to “pour heavily” in some cases and locally larger amounts of rain from Thursday evening to Saturday morning. “After the dry June, this rain is very welcome,” emphasizes the weather service on Twitter.

Because like the weather service in his Blog writes, the current month is on the way to becoming the “second warmest June since measurements began”. The number of hot days is not impressive. “And yet it was always warm like summer,” writes MeteoNews.

Specifically, the temperature deviation is currently around 3 degrees compared to the long-term average on the north side of the Alps, and lower in the south. “Seen across the country, it’s 2.8 degrees too warm.” So far, only June 2003 was warmer – and “significantly”.

In addition, June has so far been “much too dry” in many places in Switzerland, as it goes on to say. There are small exceptions thanks to some downpours and thunderstorms in the western Alps and in Ticino. In the lowlands, however, these remained rare – with the exception of June 22, when it rained widely and there were strong thunderstorms locally. MeteoNews speaks of “absolute shortage” when it comes to rain. Even the now announced rain does not change anything about the “too dry character”. (abi)

Temperatures will drop on Tuesday

Bathing fans and sunbathers watch out: Today, Monday, it’s quite sunny again, cloud fields will appear later and cumulus clouds will form over the mountains. According to MeteoNews, the temperatures are between 28 and 30 degrees.

However, a cold front is announced for Tuesday, approaching from France and Germany. According to the meteorologists from MeteoSwiss, it will be fairly sunny in the lowlands, despite cloud patches. However, the temperatures in the lowlands drop to 15 degrees in the early morning. In the afternoon they then rise again to around 25 degrees – and thus crack the summer mark. On Wednesday there should be 13 degrees early in the morning. (abi)

Despite this, around 10,000 lightning bolts were discharged in Switzerland. The cantons of Bern, Jura and Lucerne had the most lightning.

The meteorologists suspect, among other things, a connection with the Sahara dust, which had a “decisive influence” in the air. Because the resulting cloudiness and the increased formation of the sun have somewhat limited the solar radiation during the day. As a result, “the Earth system had less energy” that had to be converted by thunderstorms and winds, writes MeteoNews in their blog.
