Trader sentiment for the Paris maximum temperature on August 21 centers on ensemble guidance from Météo-France and other models, which favor a modest 23–24 °C peak under a moist, stable air mass with increased cloud cover and scattered showers. These conditions limit daytime insolation and promote evaporative cooling, keeping surface temperatures below seasonal averages near 24–25 °C. The narrow spread between the leading 23 °C (44 %) and 24 °C (36 %) outcomes reflects uncertainty in the exact timing and coverage of afternoon cloud breaks versus showers, which can shift the daily maximum by 1 °C. Radiative cooling overnight and westerly advection of cooler maritime air further constrain heating potential, while any delay in shower development could allow brief additional warming.

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.
