Trader consensus on Polymarket heavily favors a Paris high of 19°C (27%) or 18°C (26%) on March 24, driven by the latest ECMWF and Météo-France ensemble forecasts projecting peaks in this range amid a persistent high-pressure ridge over Western Europe. This setup advects mild maritime air from the Atlantic, suppressing cloud cover and boosting insolation for above-average March temperatures—historically around 13-15°C. Differentiating factors include model spread: warmer GFS outliers push toward 20°C (17.5%), while cooler boundary-layer perturbations favor 17°C (19%), with urban heat island effects in Paris potentially tipping the scale upward. Traders eye afternoon 12Z updates for resolution shifts, as small variances in boundary-layer mixing could swing outcomes by 1-2°C.

The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the Charles de Gaulle Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/fr/paris/LFPG.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.
This market can not resolve to "Yes" until all data for this date has been finalized.
The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market.
Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.
