Latest ensemble forecasts from ECMWF and GFS models project Paris's highest temperature on March 27 at 11-12°C under a mild high-pressure ridge, fueling trader consensus with 31% odds on 11°C and 26.5% on 12°C amid tight clustering. Météo-France's official outlook aligns at around 12°C daytime peak, tempered by partial cloud cover and cool northerly winds limiting advection of warmer air masses. Differentiating factors include diurnal timing—early cloud breaks could push 12°C via solar insolation, while persistent overcast favors 10-11°C—plus urban heat island effects boosting measured highs at key stations like Montsouris. Historical late-March norms average 12°C, but model spread reflects 1-2°C uncertainty from jet stream positioning. Traders eye afternoon updates for resolution shifts.

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.
