Trader consensus on Polymarket heavily favors 16°C (36.5%) and 17°C (32.0%) as Paris's highest temperature on March 23, driven by the latest ECMWF and Météo-France ensemble forecasts projecting daytime maxima in the 15-18°C range amid a mild Atlantic high-pressure ridge. Recent model updates show a subtle warming trend from southerly winds, but small uncertainties in afternoon cloud cover and boundary layer mixing differentiate the leaders: fuller sunshine could push to 17°C, while increasing stratocumulus might cap at 16°C. Historical late-March averages hover around 13°C, yet this year's anomalously warm spring—fueled by reduced Arctic cold outbreaks—supports elevated odds, with official observations resolving via Météo-France stations. Key watch: tomorrow's 12Z ECMWF run for refined probabilities.
