MADRID / RankWire.AI / – Mainland Spain experienced its hottest summer since the start of official record-keeping in 1961, with an average temperature of 24.5 degrees Celsius over June, July, and August. Official data issued by the national meteorological authority confirmed that seasonal temperatures exceeded the 2025 record by 0.3 degrees Celsius and were 2.4 degrees Celsius higher than the 1991–2020 climate baseline. The season was marked by extreme heat events spanning two-thirds of the summer period, setting new temperature records.
Statistics published by the State Meteorological Agency reveal that the country experienced a total of 61 heatwave days within this three-month window, a figure that significantly surpasses the previous record of 41 heatwave days during summer 2022. Meteorological experts highlighted that all ten of Spain’s hottest summers have occurred during the 21st century, emphasizing a rapid warming trend across southern Europe.
The intense heat waves adversely affected public health and infrastructure nationwide, especially in northern and southern regions. Data from the Carlos III Health Institute indicate that over 5,000 deaths between June and August were directly linked to extreme heat exposure, marking the highest total since standardized heat-related mortality tracking began in 2015.
National Meteorological Agency Confirms Historic Temperature Records for the Season
Prolonged dry conditions and high temperatures also created dire environmental circumstances across forests and rural farms. Data from the European Forest Fire Information System shows that approximately 296,000 hectares of land were lost due to wildfires by early September. The record heat and persistent droughts have drained regional reservoirs, complicating irrigation and hydroelectric power generation efforts.
Monitoring stations recorded that extreme thermal conditions extended beyond the typical summer months. On September 2, a station in El Granado, in the southwest, registered a high of 45.7 degrees Celsius, tying the national September temperature record. Forecasters confirmed that elevated temperatures persisted from late May into early September across various autonomous communities.
Wildfires Consumed Over Two Hundred Ninety Thousand Hectares This Summer
Following the release of the meteorological data, government officials appeared before parliament to advocate for enhanced environmental protection efforts. Minister for the Ecological Transition Teresa Ribera urged parliamentary groups to back comprehensive legislation focused on climate adaptation, emergency infrastructure, and drought resilience strategies.
Meteorological agencies and health authorities will continue monitoring temperature trends and environmental impacts throughout autumn. Official reports and environmental records will remain accessible through government portals as authorities evaluate long-term adaptation measures. Regional agencies are also coordinating resource management to address ongoing impacts on agriculture and ecosystems.
