Recent numerical weather prediction models, including GFS and DWD runs updated on September 7, show a consensus high near 24–25°C for Paris on September 8 amid persistent cloud cover, southwesterly flow, and periods of rain that limit daytime heating. This aligns with the market’s concentration of probability on 24–26°C outcomes, as cooler, moister air masses have replaced the warmer conditions observed on September 7. Historical September averages near 22.6°C provide context, yet the current pattern’s steering and moisture transport favor values slightly above the climatological mean. Traders are monitoring final model updates and observational data through the overnight period, when small shifts in cloud thickness or wind could nudge the peak by 1°C either way before markets 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.
