Spain recorded its hottest summer in 2025, according to data released the national meteorological agency AEMET on Tuesday.

The average temperature was 24.2 Celsius (75.56 Fahrenheit), going beyond the previous record of 24.1C set in 2022, and the highest figure since records began in 1961, AEMET spokesperson Ruben del Campo said at a news conference.

"We really are on this trend toward much hotter summers," Del Campo added. The last Spanish summer without a heatwave was in 2014, according to the spokesperson.

Heat waves becoming the new normal

Scientists warn that manmade climate change is causing extreme weather events. Already in June, heat records were being set in Spain, with the mercury rising to  46C in parts of the country's southwest. 

Spain endured a 16-day heatwave in August, which sparked wildfires that killed four people. With temperatures of 45C in the south of the country, it was the most intense on record, according to AEMET.

The combination of extreme temperatures with low rainfall created the perfect conditions for wildfires, Del Campo said.

The Carlos III Health Institute estimates the heatwave caused more than 1,100 deaths in mostly people older than 65.

Spain experienced three heatwaves spanning 36 days during the summer.
