Recent ensemble forecasts from ECMWF and GFS models show strong consensus for a mostly sunny day in Paris on September 15 with southwesterly flow and warm advection supporting a daily maximum near 32°C. This aligns with the market's leading 48.5% implied probability for 32°C, followed by 31°C and 33°C outcomes. Low precipitation chances and moderate humidity under building high pressure favor efficient daytime heating, though minor model spread in exact peak timing and boundary-layer mixing introduces uncertainty between 31–33°C. Historical September averages near 22°C underscore the anomalous warmth, and the next high-resolution model runs plus official Météo-France guidance will likely refine resolution odds ahead of market close.

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.
