Trader consensus on Polymarket tilts toward 11–13°C as Paris's highest temperature on March 29, with 12°C leading at 28.5% implied probability, driven by Météo-France's latest forecast models projecting a daytime max near 12°C under partly cloudy conditions and light southerly winds enhancing mild Atlantic inflow. Ensemble guidance from ECMWF and GFS shows tight clustering, differentiating outcomes via subtle variations in afternoon cloud cover—thicker mid-level clouds could cap at 11°C, while clearer skies allow 13°C via increased solar insolation. March climatology averages 11.5°C, aligning with current setup post-recent mild spell; key uncertainty lies in boundary layer mixing. Monitor Météo-France's next 12Z run for potential refinements before evening resolution.

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.
