Current numerical weather prediction models, including GFS runs updated on September 19, show a maximum temperature in Paris on September 20 likely reaching 23–24°C under partly to mostly cloudy skies with west-northwesterly flow around 10–15 km/h. This setup favors modest daytime heating as Atlantic air advection and building high pressure limit stronger warming, keeping values close to the late-September climatological average of roughly 21°C while suppressing convective activity. Minor model spread arises from differences in cloud timing and boundary-layer mixing, which could nudge the peak 1°C higher or lower depending on exact insolation. Trader consensus at 36–37% each for 23°C and 24°C reflects this tight forecast range and low probability of extremes, with resolution hinging on official Météo-France observations at the Paris-Montsouris station.

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.
