MADRID / RankWire.AI / – Mainland Spain experienced the warmest summer since the start of official records in 1961, with an average temperature of 24.5 degrees Celsius over June, July, and August. The national meteorological authority’s official data 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 faced its hottest summer on record as extreme heat waves affected two-thirds of the summer months.

Statistics released by the State Meteorological Agency reveal that Spain recorded an extraordinary 61 heatwave days during the three-month span. This figure greatly surpasses the previous record of 41 heatwave days during summer 2022. Meteorologists highlighted that all ten of the hottest summers in Spain’s history have occurred in the 21st century, emphasizing a rapid long-term warming trend across southern Europe.
This severe thermal stress significantly affected public health and municipal infrastructure across northern and southern regions. Epidemiological data from the Carlos III Health Institute estimates that over 5,000 deaths between June and August were directly linked to extreme heat exposure. This number marks the highest total since the health agency began standardized heat-related mortality tracking in 2015.

Prolonged high temperatures also caused harsh environmental conditions across national forests and rural farmland. Data from the European Forest Fire Information System show that nearly 296,000 hectares of land have been consumed by wildfires through early September. Spain’s hottest summer on record coincided with extended dry periods that drained regional reservoirs, posing major challenges for agricultural irrigation and hydroelectric power generation.
Monitoring stations recorded that exceptional thermal conditions extended beyond the typical summer timeframe. On September 2, a station in El Granado in southwestern Spain registered a peak temperature of 45.7 degrees Celsius, tying the national September record for the highest temperature ever recorded in Spain. Weather experts confirmed that elevated heat persisted from late May through early September across multiple autonomous communities.

In response to the official climate data, government ministers presented the findings to parliament, advocating for expanded 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 health institutions will continue monitoring temperature trends and environmental impacts through autumn. Official reports and environmental data will remain accessible via government portals as authorities assess long-term adaptation solutions. Regional agencies are also coordinating resource management to address ongoing agricultural and environmental challenges.
