Record-shattering heat across France this summer has propelled the market-implied probability of a new national record to 95.7%. June delivered the country’s hottest days on record, with national averages hitting 30°C and multiple cities exceeding 43°C amid repeated heatwaves, according to Météo-France and Copernicus data. Western Europe’s June-July period also set a new benchmark, surpassing prior peaks from 2003 and 2022. Persistent high temperatures, drought conditions, and climate-driven warming have created strong momentum toward an overall summer record. A dramatically cooler final stretch of August remains the main realistic path to an upset, though current patterns and extended forecasts make that outcome unlikely.
