Recent official forecasts from Météo-France and European models show an unstable airmass over Paris on August 27, with scattered showers and thunderstorms limiting solar insolation and capping daytime heating. This setup favors a maximum of 26–28°C under mostly cloudy skies and light southerly flow, consistent with the market’s heaviest weighting on 27°C (37.5%) and 28°C (27.0%). Morning temperatures near 19°C and 60–70% rain probability further suppress peak values relative to the 24.3°C climatological average. Model consensus has tightened around these thresholds in the latest 26 August runs, though small timing shifts in convective activity could still nudge the observed high one degree either way before 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.
