Multiple record-shattering heatwaves have propelled summer 2026 toward becoming France’s hottest on record, with Météo-France confirming July as the warmest month ever at a 24.9°C average and June delivering the single hottest day since 1947 at 44.3°C in Pissos. Early Copernicus data already shows the June-July period topping 2022’s prior benchmark across western Europe, while repeated red alerts and excess deaths underscore the sustained intensity. Traders have priced “Yes” near 96% because only an unprecedentedly cool August could prevent the seasonal average from eclipsing 2003’s long-standing mark. A realistic upset would require August temperatures well below normal for the entire month, an outcome that current forecasts and historical variability make highly improbable.
