This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Paris-Le Bourget Airport Station in degrees Celsius on 1 Sep '26. The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=lfpb If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source. To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °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. Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
Latest numerical weather prediction models from sources like Météo-France and ECMWF indicate a maximum temperature in Paris on September 1 likely between 23–24°C under partly cloudy skies and light westerly winds around 5–10 km/h. This positioning reflects a stable mild air mass with moderate daytime insolation, limited by variable cloud cover that reduces peak radiative heating compared to clear conditions. Ensemble spreads show the 1°C difference hinges on precise timing of any afternoon clearing and boundary-layer mixing, while historical September 1 averages near 23°C provide context. With resolution imminent, traders weigh the latest model runs against observational trends from the prior 48 hours showing minimal change.
