Forecast consensus from Météo-France and GFS-based models points to a peak near 26°C on September 2 under initially cloudy skies that clear to partly cloudy by afternoon, with light west-northwest winds near 10 km/h, low humidity, and negligible precipitation risk. This places the day slightly above the 1991–2020 average high of 23.5°C. Trader preference for 26°C (47.5%) over 25°C (44.5%) reflects minor model spread in afternoon insolation and cloud timing, while the low 6.5% on 27°C captures limited upside if clearing accelerates. Official observations through midday show temperatures climbing steadily toward the 25–26°C range without signs of stronger warming. Resolution hinges on the precise daily maximum reported by Météo-France stations.

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.
In the event which there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
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.
