Forecast consensus from official meteorological models points to a maximum temperature of 21–22°C in Paris on September 18, aligning with the market's strong implied probabilities for those outcomes. Mild westerly flow under a stable anticyclonic regime, combined with partly cloudy skies and light winds, supports gradual daytime warming to near the long-term September average high of 21.2°C. Current observations show temperatures climbing through the low 20s°C by afternoon without significant deviations from guidance. This setup leaves little room for extremes, as historical records for the date range widely but recent model runs and real-time data reinforce the narrow 21–22°C band as the most likely resolution range.

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.Forecast consensus from official meteorological models points to a maximum temperature of 21–22°C in Paris on September 18, aligning with the market's strong implied probabilities for those outcomes.
