Spain's 2025 Summer Breaks All-Time Temperature Records

Historic Heatwave Shatters Records Across Spain

Spain has experienced its hottest summer on record in 2025, with the State Meteorological Agency (AEMET) confirming unprecedented temperature levels that surpassed previous records. The summer period from June 1 to August 31 recorded an average temperature of 24.2°C across mainland Spain, marking a staggering 2.1°C above the 1991-2020 reference period average.

Record-Breaking Temperatures

The 2025 summer surpassed the previous record holder, summer 2022, by 0.1°C, making it the warmest since records began in 1961. 'This summer has been exceptional in terms of thermal anomalies, with June being particularly noteworthy as the most anomalously warm month in Spain's recorded history,' stated AEMET spokesperson María González.

Multiple Heatwaves and Extreme Events

Spain endured three major heatwaves during the summer months, with the peninsula experiencing two significant events and the Canary Islands one. The first heatwave lasted 17 days from June 18 to July 4, affecting 40 provinces and ranking as the third longest and third most extensive since 1975. The second heatwave, from August 3-18, was particularly intense with a 4.2°C anomaly and affected 42 provinces.

Jerez de la Frontera airport recorded the highest temperature at 45.8°C on August 17, followed by Morón de la Frontera at 45.2°C. Several weather stations reported their highest temperatures since records began, including Murcia, which reached 45.1°C.

Precipitation Patterns and Drought Conditions

The summer was generally dry, with precipitation reaching only 81% of normal levels, making it the 14th driest summer since 1961. Northwestern Spain, particularly Galicia and Asturias, experienced extremely dry conditions that coincided with major forest fires in August. In contrast, northeastern regions including Catalonia, Aragon, and Navarra saw above-average rainfall.

Climate Change Context

According to climate scientists, these record temperatures align with global warming trends. Spain has been experiencing increasingly warmer summers, with seven of the ten hottest summers occurring since 2011. The Mediterranean region is particularly vulnerable to climate change impacts, with projections indicating more frequent and intense heatwaves in coming decades.

Autumn Outlook

AEMET's seasonal forecast predicts a 60-70% probability of above-average temperatures across mainland Spain and the Balearic Islands for the meteorological autumn (September-November). Precipitation patterns remain uncertain, though western and central Spain are unlikely to experience particularly rainy conditions.
