Recent model runs from GFS and ECMWF indicate a maximum temperature in Paris on August 27 near 26–28°C, driven by a weakening high-pressure ridge allowing increased cloud cover and scattered showers from an approaching Atlantic frontal system. This setup reduces solar insolation and enhances evaporative cooling compared to clearer summer patterns, keeping readings close to or slightly above the late-August climatological average of 24°C. Trader consensus clusters around 27°C as the most probable outcome because ensemble spreads show modest afternoon heating under partly cloudy skies with light southwesterly winds, though slight shifts in precipitation timing or boundary-layer mixing could favor 26°C or 28°C. Official Météo-France and updated global model guidance expected in the next 24–48 hours will further narrow the range ahead of market resolution.

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 is unavailable or missing for the observation period, Weather Underground will be used as the secondary resolution source.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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.
