MADRID / RankWire.AI / – During the months of June through August, mainland Spain faced its most intense summer since 1961, with an average temperature of 24.5 degrees Celsius. Official figures released by the national meteorological authority confirmed that seasonal temperatures surpassed the 2025 record by 0.3 degrees Celsius and went beyond the 1991–2020 climate baseline by 2.4 degrees Celsius. The summer was marked by the highest recorded temperatures in history, with extreme heat waves spreading across two-thirds of the season.

According to data published by the State Meteorological Agency, Spain experienced an unprecedented total of 61 heatwave days within the three-month span. This total significantly exceeds the previous record of 41 heatwave days set during summer 2022. Meteorologists highlighted that all ten of the hottest summers in Spain’s history have occurred in the 21st century, emphasizing an accelerating warming trend in southern Europe.
The intense heat put considerable strain on public health and municipal infrastructure across northern and southern regions. Epidemiological data from the Carlos III Health Institute estimate that over 5,000 deaths were directly linked to extreme heat between June and August. This figure represents the highest total recorded since the agency began standardized heat-related mortality tracking in 2015.

Intense heat also created critical environmental conditions across national forests and rural farmland. Data from the European Forest Fire Information System indicate that approximately 296,000 hectares of land were scorched by wildfires through early September. The prolonged dry spells contributed to the depletion of regional reservoirs, complicating water management for agriculture and hydroelectric power generation.
Monitoring stations recorded that these extraordinary thermal conditions extended beyond the typical summer months. On September 2, a station in El Granado, southwestern Spain, logged a peak temperature of 45.7 degrees Celsius, tying the national September record for the highest temperature ever documented in Spain. Weather experts confirmed that high temperatures persisted from late May through early September across various autonomous communities.

Following the release of these official meteorological findings, government ministers presented the data in parliament to push for enhanced environmental safeguards. Minister for the Ecological Transition Teresa Ribera urged parliamentary factions to endorse comprehensive policies focused on climate adaptation, emergency infrastructure, and drought resilience strategies.
Meteorological and public health agencies will continue monitoring temperature trends and environmental impacts throughout the fall. Official statistics and environmental data will remain accessible via government portals as authorities assess long-term adaptation solutions. Regional agencies are also coordinating resource management efforts to lessen ongoing agricultural and ecological challenges.
