Spain's summer 2025 was the hottest ever recorded, according to the state weather agency

This summer, Spain experienced its hottest temperatures since 1961. Climate change caused more than a week of heatwaves that sparked the worst wildfire season in 30 years.

AEMET, the state weather agency, said that the summer of 2025 is 2.1 degrees Celsius hotter than the average for 1991-2020 and surpasses the previous record summer in 2022 by 0.1 degree.

Ruben del campo, AEMET spokesperson, said that in an interview, nine of the ten hottest summers on record in Spain occurred during the 21st Century, and more heat is to come.

"These summers 2022 and 2025 serve as a preview - or spoiler for what may happen at the turn of the century," del Campo stated. "One out of every three days, we've been experiencing a heatwave this summer."

Del Campo stated that Spain will need to adapt to warmer summers and continue to contribute to global efforts to curb climate changes by reducing greenhouse gas emissions.

Spain experienced three heatwaves lasting 36 days in the summer. According to AEMET, a 16-day heatwave that lasted in August was the most intense ever recorded. Temperatures in the southern part of the country reached 45C.

Global warming is accelerating, and countries around the world have experienced record heat in recent years. The summer of 2024 marked the warmest summer in the northern hemisphere, while Britain experienced its hottest summer since 1884.

According to the European Forest Fire Information System (EFFIS), data analysed by, intense heat helped fuel wildfires across the European Union that burned a record 1,03 million hectares.

AEMET reported that temperatures in the inland region of Spain's northwest region, Galicia, where some of the most severe fires occurred, were 3C higher than normal. (Reporting and editing by Ros Russell; Reporting by Charlie Devereux)
