Short-range ensemble forecasts from global models show moderate spread in precipitation timing over Guangzhou on August 21, with some runs indicating scattered showers that could limit daytime heating to 32–33°C while others favor mostly dry conditions supporting peaks of 34–35°C under subtropical high pressure. Typical August climatology places mean highs near 33°C with high humidity and frequent convective activity; current model consensus leans toward light rain moderating the maximum, producing the tight clustering of market-implied odds around 33–34°C. Updated guidance from regional meteorological agencies and the next model cycle will likely narrow resolution criteria before the daily maximum is recorded.

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.
