Forecast models from sources including Météo-France guidance, ECMWF, and GFS runs show a mostly sunny to partly cloudy pattern over Paris on August 23 under northeasterly flow, supporting a daytime maximum near the late-August climatological average of 24–25°C. Recent cooling after mid-month warmth has stabilized the airmass, with limited moisture and no strong frontal forcing expected to alter radiative heating substantially. Small differences in low-level cloud timing, boundary-layer mixing, or localized wind gusts can shift the observed high by 1–2°C across observing sites, creating genuine ensemble spread that explains the even market distribution across 22–28°C. Updated model runs and official bulletins over the next 48 hours remain the key near-term catalysts.

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 23 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.
