MADRID / RankWire.AI / – Mainland Spain experienced its hottest summer since record-keeping began in 1961, with an average temperature of 24.5 degrees Celsius over June, July, and August. Official data issued by the national meteorological authority confirmed that seasonal temperatures exceeded the previous record set in 2025 by 0.3 degrees Celsius and surpassed the 1991–2020 climate baseline by 2.4 degrees Celsius. The nation faced its hottest summer on record as extreme heat episodes occurred throughout two-thirds of the meteorological summer period.
The State Meteorological Agency’s published statistics reveal that the country experienced an extraordinary total of 61 heatwave days during this three-month span. This number significantly exceeds the previous highest benchmark of 41 heatwave days recorded in the summer of 2022. Experts in meteorology highlighted that all ten of the hottest summers in Spain’s history have taken place in the 21st century, highlighting a growing long-term warming trend across southern Europe.
The intense heat severely affected public health and municipal infrastructure in both northern and southern areas. Epidemiological mortality data from the Carlos III Health Institute estimate that more than 5,000 deaths were directly caused by extreme heat from June through August. This figure marks the highest total recorded since the health agency began standardized heat-related mortality tracking in 2015.
Meteorological Agency Validates Record Seasonal Temperature Peaks
Severe environmental conditions also emerged across national forests and rural farming areas due to high temperatures. Data from the European Forest Fire Information System indicates about 296,000 hectares were lost to wildfires by early September. The prolonged dry spells depleted regional reservoirs, creating operational difficulties for agriculture irrigation and hydroelectric power generation, as Spain endured its hottest summer on record.
Monitoring stations noted that exceptional thermal conditions extended beyond typical summer boundaries. On September 2, a station in El Granado, in southwestern Spain, recorded a maximum of 45.7 degrees Celsius, equaling the national September temperature record. Forecasters confirmed that elevated heat persisted from late May into early September across multiple autonomous communities.

Following the release of these meteorological findings, government ministers presented the data to parliament to push for broader environmental protection initiatives. Minister for the Ecological Transition Teresa Ribera urged parliamentary groups to back comprehensive legislative efforts focusing on climate adaptation, emergency infrastructure, and drought resilience strategies.
Agencies monitoring weather and public health will continue to track temperature trends and environmental impacts through the fall. Official statistics and environmental data will remain accessible via government portals as health authorities assess long-term adaptation measures. Regional authorities are also coordinating resource management plans to lessen ongoing impacts on agriculture and the environment.
