In August 2025, Spain experienced the strongest heatwave in the history of meteorological observations. Apart from the first two days of the month, abnormally high temperatures persisted across the country, setting new records for both daytime and nighttime levels.
According to data from the national meteorological service, the average temperatures between August 1 and 20 were the highest ever recorded. Previously, only August 2003 was considered so hot, but this year has surpassed even those figures.
The hottest day was August 12, when the national average temperature reached its highest not only of the current heatwave but of the entire summer. Analysis of historical data shows that such high average temperatures on August 11 and 12 have not been recorded in Spain since 1950.
Forecasts for the coming days are also bleak: new temperature records may be set on August 16 and 17. Despite a brief drop in temperatures, the heat remains the main topic of discussion for residents and visitors alike.
Absolute maximums have been registered in several regions. For example, in Zamora on August 10, the temperature reached 41.2°C, setting a new local record. In Lleida, a new maximum of 41.9°C was recorded on August 11.
Not only daytime, but also nighttime temperatures have been unusually high. In Virgen del Camino (León), on August 10, the minimum temperature reached 21.9°C, while in Segovia that same night, the thermometer did not drop below 26.2°C. The highest minimum temperature was recorded in Castello-Almassora on August 10 — 27.1°C.
Experts note that such prolonged and intense heat affects daily life, agriculture, and the country’s energy system. Authorities are advising precautionary measures, especially for vulnerable groups, and urge people to stay updated with weather forecasts.
Meteorologists emphasize that such weather events may become more frequent in the future due to global climate change. In the coming days, both Spaniards and tourists are advised to pay close attention to their health and avoid prolonged exposure to the sun.
