Recent model consensus from sources like the GFS and Met Office indicates a high near 21–22°C for Paris on September 18, 2026, under partly cloudy skies with light westerly winds and negligible precipitation. This stable autumn pattern, featuring modest daytime heating without strong advection or cloud suppression, positions 22°C as the most probable outcome at 66.5% implied probability, followed closely by 21°C and 23°C. Traders appear to weigh the narrow forecast spread and typical September diurnal range against minor uncertainties in boundary-layer mixing or local urban heat effects, with no major synoptic shifts expected to push extremes before resolution.

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 18 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.Recent model consensus from sources like the GFS and Met Office indicates a high near 21–22°C for Paris on September 18, 2026, under partly cloudy skies with light westerly winds and negligible precipitation.
