Trader consensus on Polymarket reflects tight uncertainty in forecast models for Paris's highest temperature on May 8, with implied probabilities clustered around 19–22°C as European ensemble guidance (ECMWF, GFS) centers on 20–21°C amid transitional spring weather. After a cool early May featuring northerly flows that capped May 5's high at 15°C per official observations, recent Météo-France updates show southwesterly winds ushering milder air over Île-de-France, but persistent atmospheric instability risks showers and cloud cover suppressing diurnal heating by 2–3°C. Differentiating factors include afternoon sunshine breaks potentially pushing toward 22°C versus overcast conditions favoring 18–19°C; watch hourly forecasts and new model runs through May 7 for resolution at Paris-Le Bourget Airport. Historical May averages near 19°C align with this narrow spread.
