MADRID / RankWire.AI / – Mainland Spain experienced its hottest summer since records began in 1961, with an average temperature of 24.5 degrees Celsius across 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. Spain’s summer was the warmest on record as extreme heat events affected two-thirds of the meteorological season.

The State Meteorological Agency’s published statistics show the country experienced an unprecedented 61 heatwave days during the three-month period. This figure considerably exceeds the previous record of 41 heatwave days recorded in the summer of 2022. Meteorological analysts highlighted that all ten of the hottest summers in Spain’s history have occurred in the 21st century, emphasizing a rapid long-term warming trend across southern Europe.
The extreme thermal conditions had a serious impact on public health and municipal infrastructure throughout both northern and southern regions. Epidemiological data from the Carlos III Health Institute estimate that over 5,000 deaths directly resulted from extreme heat between June and August. This is the highest total recorded since the health monitoring agency began standardized heat-related mortality tracking in 2015.
Spain Records Its Hottest Summer Ever as Heatwave Days Reach 61
Intense heat also created severe environmental challenges across national forests and rural farmland. Data from the European Forest Fire Information System indicates that around 296,000 hectares of land were burned by wildfires through early September. The prolonged dry spells drained regional reservoirs, complicating operations for agricultural irrigation and hydroelectric power generation, while the summer’s record heat added to these difficulties.
Atmospheric stations observed that the extraordinary thermal conditions extended beyond typical summer boundaries. On September 2, a station in the southwestern municipality of El Granado registered a peak of 45.7 degrees Celsius, tying Spain’s national September temperature record. Weather experts confirmed that high temperatures persisted from late May into early September across multiple autonomous communities.
Data from Meteorological Records Reveal Accelerated Warming Trends in the 21st Century
In light of these official findings, government ministers presented the data to parliament to push for enhanced environmental policies. Minister for the Ecological Transition Teresa Ribera urged parliamentary groups to support comprehensive legislation focused on climate adaptation, emergency infrastructure, and drought resilience strategies.
Meteorological agencies and public health institutions will continue monitoring temperature trends and environmental impacts throughout the autumn. Official statistical reports and environmental data records will remain accessible through government portals, aiding public health authorities’ evaluation of long-term adaptation measures. Regional authorities continue coordinating resource management efforts to address ongoing agricultural and environmental challenges.
