Trader consensus on Polymarket assigns a 73.5% implied probability to 17°C or higher as the highest temperature in Paris on April 4, driven by the latest Météo-France guidance and ensemble forecasts from ECMWF and GFS models projecting daytime highs of 17–19°C under anticipated high-pressure influence and southerly flow. This positioning reflects recent mild spring patterns across France, with above-seasonal temperatures persisting through late March into early April despite cloudy conditions and patchy rain on April 1 (8–15°C). April climatology typically sees Paris maxes around 14–16°C, but current model consensus favors warmth above historical norms. Inherent forecast uncertainty remains, with new ECMWF and GFS runs expected daily through April 3 that could refine trajectories ahead of resolution based on official station measurements.
