Spain Records Hottest September in History With 22.5°C Average Temperature

Mainland Spain experienced its warmest September since record-keeping began in 1961, with the national weather agency AEMET reporting an average temperature of 22.5°C. This exceptional heat exceeded the 1991–2020 reference period norm by 3.4°C and surpassed the historical average summer temperature of 22.1°C for the first time. The municipality of El Granado matched the all-time monthly heat record by reaching 45.7°C on September 3.

In addition to the unprecedented heat, the month was exceptionally dry, recording only 36% of normal September rainfall. AEMET issued rare red heat alerts in parts of Andalusia during a month made effectively into another summer by human-driven climate change. These extreme temperatures have triggered drought conditions and raised concerns over public health across Europe.
