Recent forecast models from European and global ensembles indicate a moderating Atlantic flow over northern France on August 21, with daytime highs likely peaking near 23–24 °C under variable cloud cover and a chance of light showers. This setup produces tight clustering around those values because small shifts in timing of any clearing or brief convective activity can alter the daily maximum by 1 °C. Paris’s urban heat-island effect and the precise siting of official thermometers add further micro-scale variability, while climatological August averages near 24 °C provide a baseline against which current guidance shows modest cooling. Market-implied odds reflect this genuine forecast spread and the proximity to resolution, with traders weighting the latest model runs and observational updates from Météo-France.

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 21 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.
