Forecast models from Chinese meteorological agencies and international sources converge on an overnight low near 23–24°C for Beijing on August 21, driven by partly cloudy skies, light southerly winds, and elevated humidity that limits radiative cooling. This aligns with seasonal norms around 21°C while reflecting the +1–2°C warmth observed through mid-August amid broader regional patterns. Trader consensus heavily favors 24°C (59% implied probability) and 23°C (41.5%), as real-time station data and short-range ensembles show little support for drops below 22°C or above 25°C given persistent urban heat effects and minimal precipitation overnight. New observational updates through the evening will refine these odds before 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 Beijing Capital International Airport Station in degrees Celsius on 21 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 Beijing Capital International Airport Station, available here: https://www.wunderground.com/history/daily/cn/beijing/ZBAA.
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.
