Current forecasts from multiple meteorological models indicate a daily maximum near 31–33 °C in Guangzhou on August 21, with widespread cloud cover, thunderstorms, and rainfall expected to limit surface heating and keep temperatures from exceeding typical late-summer values. High humidity and southeasterly flow associated with the East Asian monsoon further suppress afternoon peaks by reducing insolation and promoting convective activity. These conditions align with the market’s heaviest weighting on 31 °C, followed by 32 °C and 33 °C, while probabilities for 34 °C or higher remain low given the precipitation outlook and historical August norms around 32–34 °C. Official observations from the China Meteorological Administration will determine final resolution once the calendar day ends.

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 Guangzhou Baiyun International 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 Guangzhou Baiyun International Airport Station, available here: https://www.wunderground.com/history/daily/cn/guangzhou/ZGGG.
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.
