Recent numerical weather predictions from Météo-France, ECMWF, and GFS ensembles show Paris high temperatures on August 27 likely peaking between 27–29 °C amid partly cloudy skies, scattered showers, and southwesterly flow near 15 km/h. Trader consensus clusters on these values because model runs differ modestly on the timing and extent of afternoon cloud cover and any convective cooling, which can trim the daily maximum by 1–2 °C. Surface pressure gradients and boundary-layer moisture also influence whether solar heating reaches full potential before storms develop. Historical August averages near 24–25 °C provide context, yet current synoptic conditions favor the warmer side of climatology while retaining enough forecast spread to keep 27 °C, 28 °C, and 29 °C closely matched in the market.

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.
