Trader consensus on Polymarket assigns a 99.6% implied probability to a highest temperature of 18°C or below in Paris today, backed by real-time observations from Paris-Montsouris station showing midday readings peaking at just 15.9°C under persistent 70-75% cloud cover that limits solar insolation and daytime heating. Morning lows hovered around 10°C amid light winds of 10-15 km/h with gusts to 30 km/h, aligning with Météo-France guidance for overcast conditions and light drizzle potential, a sharp cooldown from early April highs exceeding 25°C on April 7-9. April climatology averages 16°C maxima, and model ensembles confirm subdued warming through afternoon hours. An unlikely rapid clearing could push toward 19°C, but stable stratiform clouds make this improbable as the market nears resolution via official airport records.
