The long heatwave that has gripped Spain since early August is set to come to a close as cooler air pushes in from the Atlantic. This moderate temperature drop follows a period of extreme heat with maximums rising above forty degrees Celsius in areas like the Guadalquivir valley. The State Meteorological Agency reports that this heatwave lasted for sixteen days, ranking as one of the longest experienced in recent years.

Meteorologist José Luis Camacho indicates that a disturbance entering from the northwest will increase instability, leading to possible thunderstorms in the eastern mountainous regions. Various alerts have been issued for heavy rainfall, particularly in the Pyrenees, where accumulations may exceed thirty litres per square metre in twenty-four hours.

While temperatures will significantly decline, remains of high temperatures will still be felt in the south and southeast of Spain. Regions such as Málaga, Almería, and Alicante are expected to continue experiencing tropical nights, where temperatures will not drop below twenty degrees Celsius. Nonetheless, the majority of the country will see lower minimums, falling to below twenty degrees Celsius.

By midweek, a shift in weather patterns suggests that cooler conditions will persist across most of Spain. The influx of a fresh air mass will also clear away dust from the Sahara, leading to clearer skies and fresher mornings. As Spain transitions from this heatwave, rainfall is expected to be common, particularly in northern regions, contributing to a welcome relief from the prolonged warmth.
