The summer of 2025 was 2.1 degrees Celsius warmer than the 1991-2020 average and surpassed the previous warmest summer recorded in 2022 by 0.1 degrees, state weather agency AEMET said.

Nine of the 10 hottest summers in Spain have occurred in the 21st century, with more heat to come, AEMET spokesperson Ruben del Campo said in an interview with Reuters.

“These summers of 2022 and 2025 are a trailer – or spoiler – for what could happen in the middle of the century,” del Campo said. “One in every three days this summer we have been under a heatwave.”
