MADRID / RankWire.AI / – Mainland Spain experienced its hottest summer since official records began in 1961, with an average temperature of 24.5 degrees Celsius over June, July, and August. The national meteorological authority’s official data verified that seasonal temperatures exceeded the previous record set in 2025 by 0.3 degrees Celsius and went beyond the 1991–2020 climate baseline by 2.4 degrees Celsius. The summer saw the highest temperatures on record, with extreme heat episodes spanning two-thirds of the meteorological season.
As per statistics released by the State Meteorological Agency, the country experienced an unprecedented total of 61 heatwave days during these three months. This figure significantly surpasses the previous record of 41 heatwave days during the summer of 2022. Analysts have highlighted that all ten of Spain’s hottest summers have occurred in the 21st century, emphasizing a rising long-term warming trend in southern Europe.
This intense thermal stress had a profound impact on public health and municipal infrastructure in both northern and southern regions. The Carlos III Health Institute’s epidemiological mortality data estimates that over 5,000 deaths were directly linked to extreme heat between June and August. This number represents the highest total recorded since the agency began standardized heat-related mortality monitoring in 2015.
Meteorological Agency Affirms Historic Seasonal Temperature Records
High temperatures also caused severe environmental challenges across national forest reserves and rural farmland. Data from the European Forest Fire Information System shows that nearly 296,000 hectares of land were consumed by wildfires through early September. The prolonged dry conditions during the summer led to depleted regional reservoirs, complicating operations for agricultural irrigation and hydroelectric plants.
Atmospheric monitoring stations observed that extraordinary thermal conditions persisted beyond typical summer months. On September 2, a station in El Granado, southwestern Spain, registered a peak of 45.7 degrees Celsius, tying the national September temperature record. Forecasters confirmed that elevated heat persisted from late May through early September across various autonomous communities.
Wildfires Consumed Over Two Hundred Ninety Thousand Hectares During Summer
Following the release of these official meteorological findings, government ministers presented the data to parliament, advocating for stronger environmental protection measures. Minister for the Ecological Transition Teresa Ribera urged parliamentary groups to back comprehensive legislation aimed at climate adaptation, emergency infrastructure, and drought resilience efforts.
Meteorological agencies alongside public health institutions will continue monitoring temperature trends and environmental impacts throughout the upcoming autumn. Official statistics and environmental data logs will remain accessible via government portals as authorities assess long-term adaptation strategies. Meanwhile, regional authorities are coordinating resource management plans to address ongoing agricultural and ecological challenges.
