France's summer 2026 has delivered a dominant performance, with Météo-France data confirming a national average of 24.1°C that shatters the 2003 record by a full degree. Three extended heatwaves spanning 53 days, countless station records, and unprecedented early-season peaks drove the market-implied odds for a new all-time high to 96.7%. Traders see little room for reversal given the margin and finalized seasonal numbers through August 31. The only plausible upsets would involve last-minute revisions to the official indicator or an unusually narrow definition of “summer” that excludes key weeks, though neither appears likely based on current verified reports.

This market will resolve to "Yes" if Météo-France's official seasonal climate report, the "Bilan climatique de l'été 2026," states that meteorological summer 2026 (1 June to 31 August 2026) is the warmest summer in France in the Météo-France record, which begins in 1900, as measured by the national average temperature ("température moyenne") calculated by Météo-France. Otherwise, this market will resolve to "No". For the avoidance of doubt, summer 2026 must be the single warmest summer on record. If Météo-France reports summer 2026 as tied for warmest with a prior year, or ranks it anything other than first, this market resolves to "No".
