Extreme heat has gripped France all summer, with June delivering the nation's hottest day on record and July posting the highest monthly average temperature since measurements began in 1900, easily topping the benchmarks from 2003 and 2006. Multiple prolonged heatwaves, including a fourth wave in late July, have driven national averages well above historical norms, reinforced by climate attribution studies showing intensified conditions. Traders see little chance of reversal before the seasonal close, though a dramatic cool spell across the final weeks of August remains the only plausible path to an upset finish.
