This market will resolve based on the lowest 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 lowest temperature recorded at the Paris-Le Bourget Airport Station in degrees Celsius on 14 Aug '26. The resolution source for this market will be information from Wunderground, specifically the lowest 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 Météo-France and ensemble models indicate a pronounced nocturnal cooling episode over Paris on August 14, driven by clear skies, light winds, and a shift to cooler maritime air following earlier heat. Overnight radiative cooling under these conditions, combined with dew-point suppression, supports minimum temperatures at or below 20°C, consistent with the market's near-certain implied probability. Historical mid-August baselines average 15–18°C lows, and current anomalies align with verified observations rather than model spread. Resolution hinges on official station readings; only an unexpected warm advection or urban heat island intensification could push values above the threshold.
