Current numerical weather prediction ensembles place Beijing's August 20 maximum near 32°C, with the spread across 31–33°C reflecting uncertainty in afternoon cloud cover and convective timing. Late-summer monsoon retreat allows the western Pacific subtropical high to influence the region, promoting subsidence and warming, yet scattered thunderstorms—common in Beijing's August climatology—can suppress peaks by several degrees through evaporative cooling and reduced insolation. Urban heat-island effects and soil moisture from recent showers add local variability, while model disagreement on steering flow keeps the distribution tight but unresolved until updated runs from agencies such as the China Meteorological Administration arrive within the next 48 hours.

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 Beijing Capital International Airport Station in degrees Celsius on 20 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 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.
