Official meteorological observations from the Paris-Le Bourget station established a daily maximum of 25°C on May 31, aligning with Météo-France data amid a post-heatwave cooldown across northern France. This outcome reflects verified station measurements rather than models, with the market-implied probability near 100% driven by the release of final recorded values following several days of elevated temperatures earlier in the week. Minor revisions to preliminary reports remain theoretically possible but are rare once quality-controlled data are published, while alternative outcomes below 24°C or at 26°C+ would require substantial discrepancies from the authoritative reference station.
