# France and Catalonia face extreme heat and economic strain > Live situation record from CLSTR: https://clstr.news/situations/france-summer-heatwave-response > Updated: 2026-09-10T22:02:01.000Z. Sources: 215. Developments: 25. The summer of 2026 was recorded as the hottest since 1900, with an average temperature of 24.1°C. The season was defined by three major heatwaves totaling 53 days and a significant drought, with precipitation levels 40% below seasonal norms. Wildfires in the Gironde region destroyed over 47,000 hectares, and Santé publique France reported approximately 7,300 heat-related deaths. As the season transitioned into September, southern France and Catalonia experienced an intense late-season heatwave. Météo-France issued a red alert for the Pyrénées-Orientales, while in Catalonia, Vinebre recorded a historic 42.5°C. In early September, France recorded a new national record for the month in Lavaur, Tarn, where temperatures reached 40.3°C. This extreme heat has impacted 24 cities breaking their own records, with orange alerts remaining in departments such as Ardèche, Drôme, and Vaucluse. Simultaneously, the Mediterranean Sea has experienced record-breaking warmth, continuing a trend of daily temperature records set throughout August. Scientists note that high sea temperatures can prevent nighttime cooling on coasts and increase humidity, while posing stress to marine ecosystems. The agricultural sector in France faces a crisis estimated to cost at least 5 billion euros, threatening 30,000 farms. The restaurant industry is also under strain, with the UMIH reporting that over 25% of French restaurants are recording losses. Extreme weather has also severely impacted infrastructure; the railway sector, specifically the SNCF, reported revenue losses exceeding 100 million euros due to heat-related issues like buckled rails and sagging lines. In response to these crises, Ecological Transition Minister Monique Barbut has pledged to present a five-year financing plan and new conclusions regarding the National Climate Change Adaptation Plan by the end of September. ## Claims - France experienced 53 days of heatwaves during the summer of 2026.
