Recent model consensus from sources like GFS indicates a high of 21–23°C in Paris on September 10, driven by building high pressure, light westerly winds, and clearing skies after earlier rain, consistent with early-September climatology near 22°C average maxima. This positions 22°C as the leading market outcome at 46% implied probability, with 23°C and 21°C close behind due to minor variations in afternoon peak timing and cloud cover. Official monitoring shows no significant heat advection or frontal systems expected to push extremes, though ensemble spreads allow for small revisions before resolution. Traders weigh these stable atmospheric conditions against typical forecast uncertainty in short-range guidance.

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.
