Trader consensus on Polymarket reflects tight uncertainty in Météo-France and ECMWF model ensembles, with the implied probability split nearly evenly between 11°C (32%) and 10°C (30%) as the highest temperature in Paris on March 28. Latest 00Z forecast runs show ensemble means hovering at 10.5–11°C amid a transitional spring pattern featuring mild Atlantic air moderated by northerly winds and variable cloud cover, which could cap daytime heating. Discrepancies arise from differing predictions on boundary layer mixing and insolation; GFS leans slightly warmer at 11–12°C while UKMO holds cooler. Historical March maxima average 12°C, but recent observations of persistent low-level stability have trimmed upside potential. Updated model guidance expected at 12Z will likely refine odds ahead of 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.
