The essentials
France experienced record heat in summer 2026, with July the hottest month ever recorded.
Summer 2026 marked the hottest season ever recorded in France since measurements began in 1900. The extreme temperatures were driven by three major heat waves that swept across the country during the season.
July 2026 became the hottest single month in France's recorded history. Earlier, France recorded its highest-ever thermicity index in June 2026, a measure that accounts for both temperature intensity and duration. These records underscore the unprecedented nature of the conditions experienced throughout the summer.
According to France's climate director, the extreme heat is attributed to climate change, linking the record-breaking temperatures to broader climatic patterns.

Multiple temperature milestones broken across France in 2026
Summer 2026 set three distinct temperature records: the hottest season since 1900, the hottest July ever, and the highest thermicity index in June. Three heat waves combined to create unprecedented conditions. These measurements provide objective data about climate patterns in France during this period.
Extreme heat linked to broader climate change patterns
France's climate director connects the record-breaking temperatures to climate change. The convergence of multiple record-breaking months and three consecutive heat waves demonstrates the intensity of conditions in summer 2026. This attribution reflects scientific analysis of the mechanisms behind the observed temperatures.
