Météo-France's official confirmation in early September that summer 2026 delivered a national average of 24°C—nearly a full degree above the 2003 benchmark—has locked in overwhelming trader consensus behind a yes outcome. Multiple prolonged heatwaves, record station highs across the hexagon and Corsica, and an unprecedented 53 days under official heatwave conditions created a margin that leaves little room for revision once final data settle. While late adjustments to the thermal index remain theoretically possible, historical precedent shows such shifts rarely exceed a few tenths of a degree, keeping any realistic upset scenario vanishingly small.
