MADRID / RankWire.AI / – Mainland Spain experienced its hottest summer since the start of official climate tracking in 1961, with an average temperature of 24.5 degrees Celsius over June, July, and August. Official data released by the national meteorological authority confirmed that seasonal temperatures surpassed the previous record established in 2025 by 0.3 degrees Celsius and exceeded the 1991–2020 climate baseline by 2.4 degrees Celsius. This summer set a new record as extreme heat events affected two-thirds of the meteorological season.

Statistical reports from the State Meteorological Agency reveal that the country experienced an unprecedented 61 heatwave days during the three months. This total significantly surpasses the previous high of 41 heatwave days recorded in the summer of 2022. Meteorological experts highlighted that all ten of Spain’s hottest summers in history have occurred in the 21st century, indicating a rapidly intensifying long-term warming trend across southern Europe.
The intense heat severely affected public health and infrastructure across both northern and southern regions. According to mortality data from the Carlos III Health Institute, over 5,000 deaths between June and August are directly linked to extreme heat exposure. This figure marks the highest total since the health agency began standardized heat-related mortality monitoring in 2015.
State Meteorological Agency Confirms Record-Breaking Seasonal Temperatures
Throughout the season, high temperatures created dangerous environmental conditions, impacting forests and rural farms. Data from the European Forest Fire Information System shows that nearly 296,000 hectares of land were consumed by wildfires through early September. Spain’s hottest summer on record was also marked by prolonged dry spells that drained regional reservoirs, posing serious challenges for agricultural irrigation and hydroelectric power production.
Atmospheric monitoring stations noted that exceptional heat extended beyond the usual summer timeframe. On September 2, a station in El Granado, in southwestern Spain, recorded a peak of 45.7 degrees Celsius, tying the national record for the highest temperature recorded in September. Weather forecasters confirmed that elevated heat persisted from late May into early September across multiple autonomous communities.

Following the official meteorological findings, government ministers presented the data to parliament to push for expanded environmental protection 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 agencies and public health institutions will continue monitoring temperature trends and environmental impacts throughout the autumn. Official statistical reports and environmental data logs will stay accessible via government portals as authorities assess long-term adaptation options. Regional administrations remain engaged in resource management planning to mitigate ongoing challenges to agriculture and ecosystems.
