Trader consensus on Polymarket has locked in 22°C as the highest temperature in Paris on April 15, 2026, at nearly 100% implied probability, driven by preliminary observations from the official Charles de Gaulle Airport (LFPG) station via Wunderground historical data—the market's resolution source. Hourly measurements confirmed a midday peak of 22°C under partly cloudy skies with light winds, warmer than the April climatological average of 16°C but restrained by persistent cloud cover and cooler air masses from the north, per Météo-France regional summaries. This aligns with forecast model consensus from ECMWF and GFS, which projected highs in the low 20s. Realistic challenges include rare post hoc data revisions uncovering a 23°C reading during quality control, though airport stations offer high reliability; final Wunderground data expected within 24 hours will solidify resolution.
