Last weekend was clearly marked by the very high temperatures that were felt, especially on Saturday. During that day, temperatures surpassed 40⁰C in the interior of the country, mainly in the South.
Already on Sunday, temperatures dropped substantially, with the northerly effect on the west coast being more visible.. Even so, temperatures remained high, south of the Tagus River, especially in the interior of Alentejo.
The descent will continue at the beginning of this week, with temperatures remaining relatively low for the season.. However, will the end of the week be the same?
First days of the week will be marked by relatively low temperatures
This midsummer week will start shy in the North of the country. A cooler air mass from the Atlantic is influencing the weather since yesterday, mainly in the Northwest of the mainland. Even in the south of the country, districts such as Beja and Évora, traditionally very hot at this time of year, will register temperatures well below what was seen at the weekend. Maximum temperatures can go down to around 10⁰C.
Despite a hot weekend, a mass of cold air from the Atlantic came to bring down temperatures all over the country.
the day of today it will be marked by cloudiness, especially on the western coast, as well as some rain in the Minho region, in the afternoon and at the end of the day. Temperatures will drop abruptly, especially on the coast. Already the wind will blow light to moderate from the North quadrant in the morning, spent blowing from the West in the afternoon.
The temperature recovery trend starts on Tuesday, as can be seen from the analysis of the ECMWF model. Despite this, the western coast will continue to be affected by the north winds, which, in a way, prevent the maximum temperatures from reaching very high values. In terms of cloudiness, the day will generally be clear or slightly cloudy, the exception being Minho and Douro Litoral, where there will be some cloudiness in the morning.
On Wednesday the temperatures will return to what is most usual for summer: above 30⁰C! The entire interior of the country, from the Douro Superior and Dão valleys, and from Castelo Branco to Beja, will record temperatures ranging between 30⁰C and 35⁰C. For the city of Portalegre and for the county seat, Marvão, a maximum of 33⁰C is forecast, while for Elvas the forecast indicates 34⁰C.
The island territory, as usual, has different patterns of temperature evolution. With minimum temperatures very close to maximum, summer remains relatively mild. In the Azores Archipelago, the maximum temperature will not exceed 24⁰C and the minimum will not go below 17⁰C. As for the Madeira Archipelago, temperatures will vary within this range, and throughout the week, mainly on the north coast of Madeira Island, cloudiness will be a constant presence.
In the final stretch of the week, the heat returns
Thursday will be marked by the return of high temperatures. Mercury will exceed 30⁰C in most of the country. The city of Faro will be an exception as the maximum temperature will be around 29⁰C. Already Porto, like Lisbon, will record a maximum temperature of around 32⁰C. The sky will generally be light cloudy or clear, with the exception of the areas of the North coast that will present some cloudiness during the morning.
Curiously, the Algarve coast will be an exception to the rest of the country, as the highest temperatures will be registered at the beginning of the week, Monday and Tuesday, and as the week progresses, temperatures, for example in the cities of Faro and Olhão, drop to values slightly below 30⁰C.
Friday will represent the apogee of maximum temperatures in this weekly analysis. According to the ECMWF prediction model, the high temperatures (above 35ºC) will be felt practically throughout the country, with the exception of the coast, mainly north of Cabo Carvoeiro. The city of Beja can count on a maximum temperature of around 38ºC. Vila de Nisa with 39⁰C, Vila Velha de Rodão with 40⁰C and even Castelo Branco with 38⁰C will be among the areas of the country where mercury will rise the most.
Are these temperatures an omen for a hot weekend?
