Recent model consensus from sources like GFS and ECMWF points to a minimum temperature in Paris on September 20 near 13–15°C, driven by light winds shifting northwest and partly cloudy skies that permit moderate radiational cooling overnight. High pressure maintains stable conditions with minimal cold-air advection, while dew points around 10–12°C limit further drops. Traders favor 13–14°C outcomes because ensemble spreads show slight variations in cloud timing and urban heat retention, with historical September lows averaging 11°C but recent days running 2–3°C above normal. Updated runs overnight and morning observations will refine the exact threshold before market resolution.

The resolution source for this market will be information from NOAA, specifically the lowest 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.
