Latest numerical weather prediction models, including GFS runs, indicate a minimum temperature in Paris on September 16 near 13–14°C under mostly clear skies and light northwest winds favoring radiative cooling overnight. This consensus supports the market's tight clustering around those outcomes, as subtle differences in cloud cover, wind speed, or boundary-layer mixing could shift the exact low by 1°C. Historical September averages for the city hover near 11.5°C, yet current high pressure and dry conditions favor a milder reading than the long-term norm. Traders will monitor updated model guidance and Météo-France briefings through the evening for any revisions before the overnight minimum is recorded.

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.
