MADRID / RankWire.AI / – Mainland Spain has recorded its most scorching summer since comprehensive 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 agency confirmed that seasonal temperatures exceeded the previous record set in 2025 by 0.3 degrees Celsius and surpassed the climate baseline for 1991–2020 by 2.4 degrees Celsius. The country endured its hottest summer on record, with extreme heat waves affecting two-thirds of the summer period.
Data published by the State Meteorological Agency reveal that Spain experienced an unprecedented 61 days of heatwaves during the three-month span. This number greatly exceeds the previous summer record of 41 heatwave days set in 2022. Meteorological analysts highlighted that all ten of the hottest summers in Spain’s history have occurred during the 21st century, pointing to an accelerating long-term warming trend across southern Europe.
The extreme thermal conditions significantly impacted public health and municipal infrastructure throughout both northern and southern regions. The Carlos III Health Institute’s epidemiological mortality data estimate that over 5,000 deaths between June and August were directly linked to extreme heat exposure. This figure represents the highest total recorded since the health monitoring agency began standardized heat-related mortality tracking in 2015.
Record-Breaking Summer in Spain with Sixty-One Heatwave Days
The elevated temperatures also led to severe environmental conditions across national forests and rural farms. According to the European Forest Fire Information System, approximately 296,000 hectares of land were lost to wildfires through early September. The prolonged dry spells depleted regional reservoirs, creating substantial operational difficulties for agricultural irrigation and hydroelectric power generation.
Meteorological stations observed that the extreme heat extended beyond the traditional summer months. On September 2, a station in El Granado, southwestern Spain, recorded a maximum of 45.7 degrees Celsius, tying the national September temperature record. Forecasters confirmed that intense heat persisted from late May into early September across multiple autonomous communities.

Following the release of the official climate data, government ministers presented the findings to parliament, urging increased measures for environmental protection. Minister for the Ecological Transition Teresa Ribera called on parliamentary factions to endorse comprehensive legislation aimed at climate adaptation, emergency infrastructure, and drought resilience strategies.
Meteorological agencies and public health organizations will continue monitoring temperature patterns and environmental impacts through the fall. Official statistics and environmental data will remain accessible via government portals as authorities assess long-term adaptation options. Regional authorities are also coordinating resource management plans to address ongoing agricultural and ecological challenges.
