Official Météo-France observations from the Paris-Le Bourget Airport station—the Polymarket reference—confirm a highest temperature of 23.5°C at 15:01 UTC on April 25, 2026, locking in 100% market-implied odds for the 23°C outcome amid clear skies and high-pressure ridging. This exceeded pre-event ensemble forecasts from Météo-France projecting 20–21°C maxima, driven by abundant sunshine (over 10 hours) and light winds fostering daytime heating, consistent with the warm April trend (monthly mean 12.7°C, ranking 7th highest since 1920). Trader consensus reflects validated METAR/SYNOP data, with nearby days peaking at 22.6°C (April 24). Realistic challenges include rare data revisions post-finalization or undetected sensor anomalies, as probed in prior Paris stations, though none evident here.
