Spain faces this Tuesday, August 5, 2025, on another suffocating day within the framework of the First great heat wave of the monthwhich is kept active since last weekend. As reported by the State Meteorology Agency (AEMET), much of the country will continue under notices due to extreme temperatures, with maximums that will exceed 40 degrees in areas of the central and southern peninsular.
The situation is caused by a powerful anticyclonic dorsal in height that blocks the passage of Atlantic fronts and allows the rise of a very warm air mass of African origin. This atmospheric phenomenon, known as ‘heat dome’favors heat accumulation day after day, hindering the night thermal descent and raising health risk, especially among the vulnerable population.
Extreme heat orange warnings in the peninsular center
The most affected areas will once again be the communities of the southern interior and peninsular center, with special incidence in the Henares corridor and the Metropolitan Area of Madrid, where the Aemet has activated the orange notice by Extremely high temperatures. In this region, maximums of up to 40 ° C are foreseen, with a thermal episode that will last from 1:00 p.m. to 9:00 p.m.
Values higher than 39-41 ºC are also expected in large areas of Extremadura, Castilla-La Mancha and the Guadalquivir Valleyincluding provinces such as Córdoba, Sevilla and Badajoz. The Valencian Community and some areas of the interior of Murcia and Aragon They will also record a thermal rebound, although with somewhat more moderate thresholds.
Relief in the north, but with still high temperatures
In contrast, the peninsular north (Galicia, Asturias, Cantabria and the Basque Country) will experience a slight decrease in maximum temperatures, although they will continue above normal for these dates. In areas such as Pamplona, León or Vitoria, maximums between 30 and 33 ºC are expected, with little cloudy skies and low probability of rainfall.
On the Catalan coast, including Barcelona and Tarragonathe atmosphere will be more tempered but still hot, with maximum temperatures around 30-31 ºC and the presence of mists or coastal calima during the early hours of the day. In the Balearic Islandsstable time is expected, with similar maxims and weak winds of the east.
Torrid nights and health risk
One of the most worrying aspects of the current episode is the persistence of heat also during the night. The Aemet warns that many capitals of the province of the South and the east peninsular will not register minimum below 25 ºC, giving rise to what is known as ‘torrid nights’.
In cities like Madrid, Seville, Córdoba or Murciait is expected that the temperature does not fall from the 27 ° C at the coolest moment in the morning, an exceptionally high value even for the month of August.
How long will the heat wave last?
As confirmed by the Aemet, this heat wave will continue At least until Thursday 7 or Friday, August 8although some models They point to their persistence until Saturday or even Sundaydepending on the evolution of the warm mass in height.
