The essentials
July 2026 set new French heat records with +3.8°C anomaly and 35% excess sunshine since 1900.
July 2026 became the hottest month on record in France since 1900, according to meteorological data. The month recorded a temperature anomaly of +3.8°C above the 1991-2020 normal baseline, marking a significant departure from historical averages. Beyond heat intensity, sunshine duration reached 35% above normal throughout the month, intensifying the drought conditions affecting the country.
These record-breaking climate metrics represent the latest escalation in France's 2026 extreme weather pattern. The data follows the June heatwave that claimed approximately 6,000 lives and preceded the fourth heatwave alert issued in late July, when 16 departments were placed on orange alert with temperatures reaching 42°C in southwestern regions.

Monthly records quantify unprecedented climate departure from historical norms
Meteorological measurements document July 2026 as France's warmest month in 126 years. The +3.8°C anomaly against the modern baseline and 35% excess sunshine represent measurable deviations that contextualize the severity of current conditions within instrumental records. These metrics provide quantitative evidence of the scale of climatic change occurring in 2026.
Record metrics compound effects of consecutive heatwaves throughout 2026
July's extreme measurements arrive amid multiple successive heatwave events across 2026, including June's deadly episode and July's orange alerts. The combination of record temperatures, extended sunshine, and repeated heat stress creates compounding strain on infrastructure, agriculture, and public health systems already affected by earlier extreme events in the year.
