MADRID / RankWire.AI / – Mainland Spain recorded its hottest summer since official records began in 1961, with an average temperature of 24.5 degrees Celsius over June, July, and August. Official data from the national meteorological authority confirmed that seasonal temperatures surpassed the previous record set in 2025 by 0.3 degrees Celsius and exceeded the 1991–2020 climate baseline by 2.4 degrees Celsius. The hottest summer on record was marked by extreme heat events that stretched across two-thirds of the entire summer period.
Data published by the State Meteorological Agency shows that the country experienced an unprecedented 61 heatwave days during these three months. This number significantly exceeds the previous high of 41 heatwave days recorded in the summer of 2022. Meteorologists highlighted that all ten of Spain’s hottest summers have occurred in the 21st century, pointing to an accelerating long-term warming trend across southern Europe.
The intense heat put considerable pressure on public health and municipal infrastructure across both northern and southern regions. The Carlos III Health Institute’s epidemiological mortality data estimates that more than 5,000 deaths were directly linked to extreme heat from June through August. This figure is the highest total recorded since the health agency began standardized heat-related mortality tracking in 2015.

High temperatures also caused severe environmental issues across national forests and rural farmland. The European Forest Fire Information System reports that nearly 296,000 hectares of land were consumed by wildfires up to early September. Spain’s prolonged dry spells drained regional reservoirs, creating major operational challenges for agricultural irrigation and hydroelectric power generation.
Monitoring stations noted that the exceptional heat extended beyond typical summer months. On September 2, a station in the southwestern town of El Granado recorded a peak temperature of 45.7 degrees Celsius, tying the national September temperature record. Weather experts confirmed that elevated heat persisted from late May into early September across multiple autonomous communities.

In response to these meteorological findings, government ministers appeared before parliament to advocate for enhanced environmental measures. Minister for the Ecological Transition Teresa Ribera urged parliamentary groups to back comprehensive legislation aimed at climate adaptation, emergency infrastructure, and drought resilience strategies.
Meteorological and public health agencies will continue monitoring temperature trends and environmental impacts through the fall. Official reports and environmental data will remain accessible via government portals as authorities evaluate long-term adaptation strategies. Regional bodies are also coordinating resource management efforts to address ongoing agricultural and environmental challenges.
