Recent forecasts from agencies including the Hong Kong Observatory and China Meteorological Administration point to a daily high in Beijing near 31–33°C on August 21, with possible afternoon thunderstorms and increasing cloud cover expected to moderate peak readings. Seasonal climatology shows typical late-August maxima around 30–32°C, while current model consensus and observed humidity levels support trader emphasis on the 33°C outcome. Thunderstorm timing and steering patterns remain key variables that could either cap temperatures below 34°C or allow brief spikes if skies clear earlier than projected. Market-implied odds align with this evidence-based range rather than outlier warmer scenarios.

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 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 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.
