Latest forecast guidance from global models indicates a daytime maximum of 23–24°C in Paris on September 20 under partly to mostly cloudy skies with moderate westerly to northwesterly winds around 7–9 mph. This positions trader consensus near the upper end of the normal range for the date, where the 1991–2020 average high is about 21°C. Differentiating outcomes hinge on cloud cover thickness and timing, which control solar insolation and surface heating rates, alongside boundary-layer mixing from winds that can limit peak temperatures. Minor model spread in low-level moisture and frontal timing keeps 22°C and 25°C viable but less probable, with resolution depending on official Météo-France observations.

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 20 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.
In the event that 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 will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
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 forecast guidance from global models indicates a daytime maximum of 23–24°C in Paris on September 20 under partly to mostly cloudy skies with moderate westerly to northwesterly winds around 7–9 mph.
