Recent forecast model runs from European and global ensembles show Paris maximum temperatures on August 9 clustering between 32–35 °C under a strengthening high-pressure ridge advecting warm continental air, with light easterly winds limiting mixing. Slight divergences arise from timing of possible afternoon cumulus development and the strength of the urban heat island effect at official Météo-France stations, pushing some guidance toward 33 °C while others reach 34–35 °C. These narrow spreads explain the near-even market split between the leading 33 °C and 34 °C outcomes, with lower probabilities assigned to 32 °C or 35 °C reflecting residual model spread and the single-day resolution window. Updated runs and local observations tomorrow morning will further narrow the range before the daily maximum is recorded.

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 9 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.
