MADRID / RankWire.AI / – Mainland Spain recorded its hottest summer since official data collection began in 1961, with an average temperature of 24.5 degrees Celsius over June, July, and August. Official figures from 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 country’s hottest summer on record was characterized by extreme heat events spanning two-thirds of the meteorological season.

Statistics published by the State Meteorological Agency reveal that the nation experienced an unprecedented 61 heatwave days within the three months. This total far exceeds the previous record of 41 heatwave days during summer 2022. Analysts emphasize that all ten of the hottest summers in Spain’s history have taken place in the 21st century, highlighting a rapid acceleration in long-term warming trends across southern Europe.
The severe thermal conditions significantly affected public health outcomes and municipal infrastructure across 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 between June and August. This figure represents the highest total recorded since the health monitoring agency began tracking heat-related mortality systematically in 2015.

High temperatures also caused severe environmental conditions across national forests and rural farmlands. Data from the European Forest Fire Information System indicate that roughly 296,000 hectares of land were lost to wildfires through early September. The summer’s prolonged dry spells drained regional reservoirs, creating operational difficulties for agricultural irrigation systems and hydroelectric plants, as Spain faced its hottest summer on record.
Atmospheric monitoring stations reported that the extreme thermal conditions extended beyond typical summer months. On September 2, a station in El Granado, in southwestern Spain, recorded a peak temperature of 45.7 degrees Celsius, tying the national September record. Forecasters confirmed that elevated heat persisted from late May into early September across multiple autonomous communities.

In light of the official meteorological data, government ministers presented the findings to parliament to push for stronger environmental measures. Minister for the Ecological Transition Teresa Ribera urged parliamentary groups to endorse comprehensive legislation focused on climate adaptation, emergency infrastructure, and drought resilience strategies.
Meteorological agencies and public health institutions will continue monitoring temperature developments and environmental impacts through the fall. Official reports and environmental data will remain accessible via government portals as authorities assess long-term adaptation strategies. Regional agencies are also coordinating resource management efforts to address ongoing agricultural and environmental challenges.
