Trader consensus on Polymarket assigns a 100% implied probability to a highest temperature of 24°C in Paris on May 9, confirmed by official Météo-France observations at the Paris-Le Bourget Airport station—the market's resolution source—which recorded a daytime maximum of 24°C amid sunny intervals transitioning to cloudier conditions, light winds, and no precipitation. This outcome aligned precisely with pre-event forecast consensus from ECMWF, NOAA GFS, and Météo-France AROME ensembles clustering at 23–25°C, elevated 5°C above the historical May 9 norm of 19°C under a stabilizing high-pressure ridge over northern France. Realistic challenges, such as rare sensor recalibration or late data revisions, proved negligible, with intraday peaks already hitting 24°C by early afternoon validating the positioning.
