Faced with the stifling temperatures of these days, even on the Cantabrian coast, the heat wave will end today with the arrival of an Atlantic front associated with the Betty squall and a notable drop in values in Galicia, the upper Ebro and the Cantabrian Sea, which in its eastern part will have an extraordinary fall.
Despite the effects that the influence of the storm will have on these areas, which has previously shaken Ireland and part of the United Kingdom with heavy rains, temperatures in Spain will still remain significantly high in the southern half of the peninsula, the northeast and the archipelagos, according to the State Meteorological Agency (Aemet).
In the eastern Cantabrian Sea, the expected temperature drop will be very pronounced; Faced with temperatures these days above 40ºC in large areas of northern Spain, and especially the Basque Country, with values of even 42ºC, the predictions for today place the maximum levels well below these levels, for example, in Bilbao and Saint Sebastian.
The marked thermal drop in those areas of the Peninsula will continue over the weekend, with probable showers and strong storms on Saturday in Catalonia and the rest of the Pyrenees, without ruling out the Valencian Community and southern Iberia. However, it is still expected to reach 34ºC-36ºC in the southern half, the northeast and the archipelagos, even 38ºC-40ºC in the Guadalquivir. The minimums will not drop below 24ºC-26ºC in the Mediterranean area.
On Saturday the decline will continue in the north and temperatures will drop significantly in large areas of the northwest half of the peninsula. However, they will continue to be significantly high in the southern and southeastern thirds of the peninsula, as well as in both archipelagos.
On said weekend day, the maximum temperatures in Basque, Galician cities or on the Cantabrian coast will not exceed 21ºC. All in all, despite the situation in the north of the country, it will still be possible to exceed 35ºC that day in the southern and southeastern thirds of the peninsula, Mallorca and areas of the Canary Islands, even 40ºC in the Guadalquivir. The minimums will not drop below 25ºC degrees on Saturday in the Mediterranean area and the Guadalquivir, according to Aemet.
The meteorological agency confirmed this Thursday that yesterday was the warmest day of the summer since there are records of temperatures and that 17 records of warm days have already been registered in Spain in 2023. In addition, it warned that the current heat wave “ It is the most intense and prolonged of this year”. According to José Ángel Núñez, one of the Aemet spokespersons, this heat wave "places three days among the ten warmest in Spain since at least 1950." The average temperature on Wednesday is the third highest in the historical series, after the records of August 14, 2021 and August 10, 2012. Tuesday the 22nd is the fourth in the series, and Monday the 21st, the ninth.
