MADRID / RankWire.AI / – Mainland Spain experienced its hottest summer since the beginning of official records in 1961, with an average temperature of 24.5 degrees Celsius across June, July, and August. The national meteorological authority confirmed that the seasonal temperatures beat the previous record set in 2025 by 0.3 degrees Celsius and went beyond the 1991–2020 climate baseline by 2.4 degrees Celsius. This record heat summer was marked by extreme heat events spanning two-thirds of the three-month period.

The State Meteorological Agency’s statistical data shows that the country experienced an unprecedented total of 61 heatwave days during the summer quarter. This figure significantly surpasses the previous record of 41 heatwave days during summer 2022. Meteorologists emphasize that all of the ten hottest summers in Spain’s history have occurred in the 21st century, highlighting a rapid long-term warming trend across southern Europe.
The extreme heat severely affected public health and infrastructure across both northern and southern parts of the country. The Carlos III Health Institute’s epidemiological mortality data estimates that over 5,000 deaths were directly linked to extreme heat from June to August. This is the highest total recorded since the health agency began standardized heat-related mortality tracking in 2015.
Meteorological Agency Confirms Peak Seasonal Temperatures in History
High temperatures also created severe environmental conditions in national forests and rural farmlands. Data from the European Forest Fire Information System indicates around 296,000 hectares of land were destroyed by wildfires as of early September. The prolonged dry spells drained regional reservoirs, causing major operational difficulties for agricultural irrigation systems and hydroelectric plants, as Spain experienced its hottest summer on record.
Monitoring stations reported that extraordinary thermal conditions extended beyond typical summer months. On September 2, a station in El Granado, in the southwest, recorded a peak temperature of 45.7 degrees Celsius, equaling the national September temperature record. Forecasters confirmed that elevated heat persisted from late May through early September across multiple autonomous communities.
Wildfires Burned Over Two Hundred Ninety Thousand Hectares During Summer
In light of the meteorological findings, government ministers presented the data before parliament to push for stronger environmental protections. 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 and public health authorities will continue monitoring temperature trends and environmental impacts throughout the autumn. Official reports and environmental data logs will remain accessible via government portals as authorities assess long-term adaptation measures. Meanwhile, regional agencies coordinate resource management efforts to address ongoing impacts on agriculture and ecosystems.
