Recent ensemble forecasts from Météo-France and other models indicate overnight lows in Paris clustering around 17–19°C on August 18, following a mid-August heatwave and subsequent cooling trend driven by Atlantic air advection under partly cloudy skies. Trader sentiment remains tightly balanced because small differences in cloud cover, wind speed, and radiative cooling rates—key controls on minimum temperature—can shift outcomes by 1–2°C. Historical late-summer climatology supports this narrow range, with limited radiative cooling expected in an urban setting. Updated model runs and official guidance over the next 48 hours will likely refine these probabilities ahead of market resolution.

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 18 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 ensemble forecasts from Météo-France and other models indicate overnight lows in Paris clustering around 17–19°C on August 18, following a mid-August heatwave and subsequent cooling trend driven by Atlantic air advection under partly cloudy skies.
