MADRID / RankWire.AI / – Mainland Spain experienced its most scorching summer since official records began in 1961, with an average temperature of 24.5 degrees Celsius during June, July, and August. Official data issued by 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 country faced the hottest summer on record as extreme heat episodes extended over two-thirds of the summer period.
According to statistics published by the State Meteorological Agency, Spain experienced a record-breaking total of 61 heatwave days during this three-month span. This total considerably surpasses the previous record of 41 heatwave days during summer 2022. Meteorological experts emphasized that all ten of Spain’s hottest summers have occurred in the 21st century, highlighting an accelerating long-term warming trend across southern Europe.
The extreme heat had a significant impact on public health and municipal infrastructure in both northern and southern regions. Epidemiological data from the Carlos III Health Institute estimated that more than 5,000 fatalities between June and August were directly linked to extreme heat exposure. This marks the highest number recorded since the health agency began standardized heat-related mortality tracking in 2015.

High temperatures also created severe conditions in national forest reserves and rural agricultural zones. Data from the European Forest Fire Information System indicates that approximately 296,000 hectares of land have been destroyed by wildfires through early September. Spain’s hottest summer on record coincided with prolonged dry spells that depleted regional reservoirs, complicating operations for agricultural irrigation and hydroelectric facilities.
Atmospheric monitoring stations reported that these extreme thermal conditions extended beyond the usual summer timeframe. On September 2, a station in El Granado, in the southwest, registered a peak temperature of 45.7 degrees Celsius, tying the national record for September’s highest temperature ever recorded in Spain. Weather forecasters confirmed that elevated heat persisted from late May into early September across multiple autonomous communities.

Responding to the official meteorological data, government ministers presented the findings to parliament to push for expanded environmental protection initiatives. Minister for the Ecological Transition Teresa Ribera urged parliamentary factions to back comprehensive legislation focusing 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 season. Official statistical reports and environmental data logs will remain accessible via government portals, as health authorities assess long-term adaptation plans. Regional authorities are also coordinating resource management efforts to mitigate ongoing agricultural and ecological challenges.
