During the last days, the Aemet (State Meteorological Agency) has been warning of a new wave of extreme heat, which is expected to be the most suffocating of the summer. This Sunday, the agency has issued a new update with details about what we can expect in the different areas of the country as of this Monday, August 7, which will be when this hot event begins..

As Aemet explains, this phenomenon will be caused by “a very hot and dry African continental air mass”, which is added to “the high insolation characteristic of this time of year”.. During the weekend we have already experienced an increase in temperatures, after the truce that we had had in previous days with a drop in part of the country. But it will be from Monday when this new heat wave begins in most of the Peninsula, although some areas will get rid of its most scorching effects.

During the days of Monday and Tuesday, almost the entire peninsular area will notice an increase in temperature, except in the Mediterranean area, where it will drop. These days, the peninsular southwest quadrant will be especially affected, being able to reach 40-42 degrees. In addition, the northern half is going to experience a notable change, and there could be temperatures of 36-40 degrees even in places like Galicia and the interior of the Cantabrian Sea, which until now had enjoyed a “relatively cool” summer..

The hottest day of this heat wave will be Wednesday, when “42-44 degrees could be reached or exceeded in large areas of the southern half and central area, and 40 degrees in areas of the eastern Cantabrian Sea, center of the plateau north and Ebro valley”. Of course, in the western end there will begin to be a decrease during that day.

Already on Thursday, “the temperatures will continue to be high, but milder than the previous days”, and they will begin to drop in the northwest of the peninsula, a decrease that will gradually spread to the rest of the country during the following days. Of course, the Aemet warns that “the uncertainty of the atmospheric evolution is high”, and it is still not entirely clear that this heat wave will end on Thursday, but that it could last even longer.

Not only will it be very hot during the central hours of the day, but the nights will also be especially warm. In many parts of the country there will be more than 20 degrees at night, and they could even exceed 25 “in the southern half, central zone and Mediterranean area.”.

The literals of the Mediterranean area, yes, will be less affected in general by the extreme heat of this entire event, along with the coasts of the western Cantabrian and Galicia. With regard to the Canary Islands, the increase in heat will arrive a little later and for Thursday “an episode of high temperatures” is expected, although it is not yet clear if it will be possible to speak of a heat wave on the islands..
