It has not yet officially arrived, but it is already noticeable. The temperatures continue their escalation this Sunday, with maximums above 35 degrees in large areas of the southern half of the peninsula, according to the State Meteorological Agency (Aemet). And a whole day before the third heat wave of the summer officially begins, temperatures will continue to rise, except for the maximum in the northern third of the peninsula, northern Balearic Islands and eastern areas.
According to predictions, it is expected to reach 35 degrees in the southern half of the peninsular Atlantic slope, as well as 40 in the valleys of its main rivers.
Jaén will be the capital of the province with the highest maximum (40 degrees), followed by Cáceres, Ciudad Real, Granada and Huelva, all with 39. On the other hand, San Sebastián and Santander will not exceed 23 degrees.
Slightly cloudy or clear skies will be the tonic in a large part of the country, although clouds are expected in the north of Galicia and the Cantabrian area, with light and scattered rains in its eastern half. This cloudiness will tend to decrease as the day progresses.
There will also be intervals of low morning clouds in neighboring areas to the south of the Cantabrian mountain range, as well as in eastern Iberia and the Pyrenees.
On the other hand, cloudy skies or with cloudy intervals are expected in eastern Catalonia. There, there can be weak rainfall on the Barcelona coast, which will spread to inland areas and southern coasts of the community in the afternoon, when it could be more intense. It is not ruled out that they will also affect the north of the Balearic Islands, where cloudy intervals will predominate.
In the Canary Islands, there will be cloudy intervals in the north of the higher relief islands, especially in the eastern ones, where there could be some weak precipitation.
Strong winds will blow from the north and northeast on the coasts of Galicia, from the east in the Strait, from the north wind in Ampurdán, from the north and northwest in the Canary Islands, from the north and east in the Balearic Islands and north wind in the Ebro, with very strong gusts in the lower Ebro
The head of Climatology of the State Meteorological Agency, José Ángel Núñez Mora. warns that the sea water is already 28 degrees in Valencia and 20 in Malaga this summer and that soon it will exceed 30 degrees in the sea off the Valencian coast and will exceed 20 in the most western waters and close to the Strait of Gibraltar.
The almost habit of seeing how records and historical temperature figures are broken year after year makes them take for ordinary phenomena that are not, which have great consequences for the environment and ecosystems.
In this way, the increase in degrees in water temperature goes beyond a game of numbers and statistics, as it translates into changes in sea conditions over the years and its "tropicalization", which entails " environmental changes that are transferred to living beings and marine organisms".
Marine life can be threatened by "exotic invasive species that live in subtropical areas, warmer seas, and that can get here by currents, adapting perfectly because the sea temperature allows them to survive, thus representing a competitor to the fauna autochthonous, it can displace it", warns the researcher.
In addition to these effects on biodiversity, indirect changes are also originated, such as the erosion of the coastline derived from cold drops and storms that, according to Gras, arise "from excessive heating of water columns."
Likewise, the DANA typical of the Mediterranean areas of the peninsula will increase their frequency and power due to the greater evaporation of seawater, which entails rainfall and higher energy waves.
Thus, he concludes that 30 degrees will soon be exceeded in the sea off the Valencian coast and 20 degrees will be exceeded in the westernmost waters and closest to the Strait of Gibraltar in the country, thus shortening an ever smaller difference between the temperatures indicated by the thermometers. out and in the water.
