MADRID / RankWire.AI / – Mainland Spain recorded its most intense summer since data collection began in 1961, with an average temperature of 24.5 degrees Celsius over June, July, and August. Official figures issued by the national meteorological authority confirmed that the seasonal temperatures surpassed the 2025 record by 0.3 degrees Celsius and exceeded the climate baseline from 1991–2020 by 2.4 degrees Celsius. The summer’s heat was unprecedented, with extreme heat events affecting two-thirds of the meteorological season.
The State Meteorological Agency’s statistical data revealed that the country faced a historic total of 61 heatwave days during these three months. This figure significantly surpasses the previous record of 41 heatwave days set in the summer of 2022. Meteorological experts highlighted that all ten of Spain’s hottest summers have taken place in the 21st century, emphasizing a rapid long-term warming trend across southern Europe.
The severe heat stress had a profound impact on public health and municipal infrastructure throughout both northern and southern parts of Spain. According to epidemiological data from the Carlos III Health Institute, over 5,000 deaths were directly linked to extreme heat from June through August. This is the highest total recorded since the agency began standardized heat-related mortality monitoring in 2015.
Meteorological Authority Validates Historic Seasonal Temperature Records
The elevated temperatures also caused critical environmental conditions across national forests and rural agricultural areas. Data from the European Forest Fire Information System shows that approximately 296,000 hectares of land have been burned by wildfires through early September. The prolonged dry spells drained regional reservoirs, creating major operational hurdles for irrigation systems and hydroelectric power plants.
Atmospheric monitoring stations reported that extraordinary heat persisted beyond the usual summer timeframe. On September 2, a station in El Granado, in southwestern Spain, recorded a peak temperature of 45.7 degrees Celsius, tying the national record for the highest temperature in September. Forecasters confirmed that high heat levels extended from late May into early September across several autonomous communities.

Following the release of the official meteorological data, government officials presented these findings to parliament, urging the implementation of broader environmental protection policies. Minister for the Ecological Transition Teresa Ribera appealed to parliamentary groups to back comprehensive legislation focused on climate adaptation, emergency infrastructure, and drought resilience strategies.
Meteorological agencies and public health institutions will continue to monitor temperature patterns and environmental impacts throughout the fall. Official statistics and environmental data will remain accessible via government portals as public health authorities assess long-term adaptation measures. Regional authorities are also coordinating resource management plans to address ongoing challenges in agriculture and environmental preservation.
