Trader consensus on Polymarket closely mirrors the tight clustering in the latest ECMWF and GFS model runs, projecting Paris's highest temperature on April 3 at 12.5–13.5°C under overcast conditions that limit solar insolation and daytime heating. Météo-France's high-resolution guidance tilts toward 12°C as the maximum, citing persistent cloud cover and mild northerly flow below the early April climatological average of 15°C, giving it a slight edge over 13°C scenarios requiring partial clearing. Key differentiators include cloud timing and boundary layer mixing, with inherent short-range forecast uncertainty amplified by model spread; watch for afternoon observations and updated 12Z runs from NOAA and ECMWF for potential shifts ahead of resolution using official Paris station data.

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.
