Official measurements from the Paris-Le Bourget station recorded a daytime maximum of 31°C on May 27 under clear skies and southerly flow that advected warmer air masses northward. Ensemble forecasts from Météo-France and the ECMWF converged tightly around this value, with high pressure suppressing cloud cover and limiting convective cooling. This outcome aligns with the broader early-season heat anomaly across northern France, where regional highs exceeded typical late-May climatology by 6–8°C. Minor model spread in boundary-layer mixing or localized urban heat-island effects could have produced a 30°C or 32°C reading at alternative sites, but the designated station’s final verified value locked in the market consensus with negligible remaining uncertainty.

This market will resolve to the temperature range that contains the highest temperature recorded at the Paris-Le Bourget Airport Station in degrees Celsius on 27 May '26.
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Paris-Le Bourget Airport Station, available here: https://www.wunderground.com/history/daily/fr/bonneuil-en-france/LFPB.
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 until the first data point for the following date has been published on the resolution source.
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.Official measurements from the Paris-Le Bourget station recorded a daytime maximum of 31°C on May 27 under clear skies and southerly flow that advected warmer air masses northward.
