Spain is immersed in an “unusual warm episode” for the season known as the San Martín summer, which will leave maximum temperatures between 25 and 30 degrees in large areas this week, according to the forecast of the State Meteorological Agency (Aemet).

The most striking thing about the next few days will be the very high temperatures for the time of year, which will be between “5 and 10 degrees above normal”, in many parts of the peninsula, especially in the north and east, anticipates the agency’s spokesperson, Rubén del Campo.

The temperatures will be truly anomalous “every day” between the 11th and until the next day the 15th, to the point that the records of 1950 could be surpassed, continues the person in charge.

This Tuesday it will exceed 30 degrees in Murcia. Close to that record they will stay in other Mediterranean provinces, such as Alicante, Tarragona, Valencia or Girona. They will also touch 30 in Santa Cruz de Tenerife or Las Palmas de Gran Canaria.

The exception will once again be in the north. An Atlantic front is expected to affect the northwest of the peninsula this Tuesday, leaving cloudy or overcast skies and precipitation in Galicia and the western Cantabrian environment, with the probability that it will become persistent in the west of this community. Throughout the day they will end up spreading, generally in a weak way.

In the rest of the Atlantic slope there will be abundant low morning cloudiness, as well as in depressions in the northeast, with probable morning mists and fogs in the northeast and on the southern plateau, especially in its valleys. They are also expected in Mallorca and in mountain areas of the northwest of the peninsula.

Temperatures will be high for the season most of the week, with a drop between Thursday and Friday. However, there will be a rebound during the weekend in the Mediterranean, where temperatures may exceed 30 degrees, as in the Canary Islands, Aemet anticipates.

After enduring the unusually high temperatures of this San Martín summer, there will be an abrupt drop in temperatures. “Subsequently, although there is still a long way to go, we could have an episode of lower than normal temperatures,” the agency notes in a thread on X (formerly Twitter), although it does not specify dates.
