Latest ensemble forecasts from ECMWF and GFS models drive the tight clustering of trader odds around 11°C (30.5%), 13°C (30.0%), and 12°C (27.0%) for Paris's highest temperature on March 25, with mean projections centering on 12°C amid a mild high-pressure ridge over Western Europe. Differentiating factors include subtle variations in cloud cover—potentially suppressing peaks to 11°C under thicker stratus, or allowing 13°C with clearer skies—and shortwave solar insolation boosted by lengthening days, though northerly winds could temper advection of warmer air masses. Historical late-March averages (~12°C max) align with this consensus, but diurnal timing and microscale urban heat effects add uncertainty, keeping lower and higher outcomes sidelined below 10% as models show low spread. 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.
