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 across June, July, and August. Official data from 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. This record heat was accompanied by extreme heatwave conditions spanning two-thirds of the summer months, marking Spain’s hottest summer on record.
Data published by the State Meteorological Agency reveals that the country experienced an unprecedented 61 heatwave days over the three-month period, a figure that considerably surpasses the previous summer record of 41 heatwave days set in 2022. Meteorological experts highlighted that all ten of the hottest summers in Spain’s history have occurred in the 21st century, illustrating a rapidly accelerating warming trend across southern Europe.
This intense heat placed significant strain on public health and municipal infrastructure throughout both northern and southern regions. The Carlos III Health Institute’s epidemiological mortality tracking estimated that over 5,000 fatalities between June and August were directly linked to extreme heat, representing the highest total recorded since the agency began standardized heat-related mortality tracking in 2015.

Elevated temperatures also led to dire environmental conditions across Spain’s forests and rural farmland. The European Forest Fire Information System reports that roughly 296,000 hectares of land have been consumed by wildfires through early September. The prolonged dry spells, which depleted regional reservoirs, created significant operational difficulties for agricultural irrigation and hydroelectric plants, further exacerbating the summer’s extreme conditions.
Atmospheric monitoring stations observed that these extraordinary thermal conditions extended beyond the typical summer period. On September 2, a station in the southwestern town of El Granado registered a peak temperature of 45.7 degrees Celsius, tying the national September record. Forecasters confirmed that high heat persisted from late May into early September across several autonomous communities.

Following these official meteorological findings, government ministers presented the data to parliament to push for broader environmental protections. Minister for the Ecological Transition Teresa Ribera urged parliamentary factions to back comprehensive legislation aimed at climate adaptation, emergency infrastructure, and drought mitigation strategies.
Meteorological agencies and health institutions will continue monitoring temperature trends and environmental impacts throughout autumn. Official statistics and environmental data will remain accessible via government portals as authorities assess long-term adaptation plans. Regional governments are also coordinating resource management strategies to address ongoing challenges to agriculture and ecosystems caused by the extreme summer conditions.
