Spain records second-hottest June on record with nearly 900 heat-related deaths

Spain has just recorded its second-hottest June since records began, according to provisional data from the State Meteorological Agency (Aemet). The agency has classified the month as 'extremely warm', a category reserved for exceptionally abnormal events.

The average temperature across mainland Spain was 23.2 °C, 3.2 °C above the average for the 1991–2020 period. Only June 2025, with an average of 23.6 °C, has been hotter in the Aemet historical series, which began in 1961.

The heatwave that marked the end of the month also broke several daily records. On 22 and 23 June, Spain recorded the two hottest June days since at least 1950. The agency described the episode as 'extraordinary' because of its intensity, duration and geographical extent, especially in the northern half of the mainland, where numerous temperature records were broken.

The extreme heat also had a major impact on health. The daily all-cause mortality monitoring system (MoMo), run by the Ministry of Health, provisionally estimates nearly 900 deaths attributable to high temperatures during the month. More than 600 of those deaths were concentrated in the week of the heatwave.
