MADRID / RankWire.AI / – Mainland Spain experienced its hottest summer on record since official data collection began in 1961, with an average temperature of 24.5 degrees Celsius across June, July, and August. Official figures from the national meteorological authority confirmed that seasonal temperatures surpassed the previous record set in 2025 by 0.3 degrees Celsius and exceeded the climate baseline of 1991–2020 by 2.4 degrees Celsius. The hottest summer on record saw prolonged extreme heat events affecting two-thirds of the meteorological summer period.
Statistical data published by the State Meteorological Agency reveals that the country experienced an unprecedented total of 61 heatwave days during the three-month span. This total significantly exceeds the previous record of 41 heatwave days during the summer of 2022. Experts in meteorology highlighted that all ten of Spain’s hottest summers have occurred in the 21st century, highlighting a rapid long-term warming trend across southern Europe.
The intense heatwave significantly affected public health and municipal infrastructure in both northern and southern parts of the country. Epidemiological data from the Carlos III Health Institute estimated that over 5,000 deaths were directly caused by extreme heat between June and August. This represents the highest number of heat-related deaths recorded since the health agency began standardized mortality tracking related to heat in 2015.
Meteorological Authority Confirms Record Seasonal Temperature Peaks
Environmental conditions worsened across national forests and rural farmlands due to high temperatures. Data from the European Forest Fire Information System indicates that roughly 296,000 hectares of land were burned by wildfires up to early September. The extended dry spells caused by the heat depleted regional reservoirs, creating major operational issues for agricultural irrigation systems and hydroelectric power plants.
Atmospheric monitoring stations recorded that these extraordinary thermal conditions went beyond typical summer boundaries. On September 2, a station in the southwestern municipality of El Granado measured a peak temperature of 45.7 degrees Celsius, tying the national September temperature record. Forecasters confirmed that high heat persisted from late May into early September across several autonomous communities.
Over Two Hundred Ninety Thousand Hectares Burned in Summer Wildfires
Following the release of official meteorological data, government ministers presented the findings to parliament to push for enhanced environmental safeguards. Minister for the Ecological Transition Teresa Ribera urged parliamentary groups to back comprehensive laws focused on climate adaptation, emergency infrastructure, and drought resilience.
Meteorological agencies and public health institutions will continue monitoring temperature patterns and environmental effects throughout the autumn. Official statistics and environmental data logs will remain available through government portals as health authorities assess long-term adaptation strategies. Regional governments continue coordinating resource management to lessen ongoing impacts on agriculture and ecosystems.
