This market will resolve based on the highest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section. This market will resolve to the temperature range that contains the highest temperature recorded at the Paris-Le Bourget Airport Station in degrees Celsius on 20 Aug '26. The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Paris-Le Bourget Airport Station, available here: https://www.wunderground.com/history/daily/fr/bonneuil-en-france/LFPB. To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °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.
Recent forecasts from sources including Météo-France analogs, ECMWF and GFS model runs, and local outlets converge on a daily maximum of 24–26 °C for Paris on 20 August 2026, with 25 °C emerging as the mode. Persistent Atlantic troughing and associated cloud cover have limited insolation, keeping surface temperatures below the seasonal 75–78 °F (24–26 °C) climatological peak while light showers or overcast conditions further suppress afternoon warming. Ensemble spread remains narrow because the event is less than 24 hours away, so resolution will hinge on the precise timing of any clearing and the official Paris-Montsouris or Orly station reading. Traders have therefore concentrated probability mass on the 24–26 °C band, treating deviations beyond that range as low-likelihood outliers under current synoptic conditions.
