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 Zhengzhou Xinzheng 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 Zhengzhou Xinzheng International Airport Station, available here: https://www.wunderground.com/history/daily/cn/zhengzhou/ZHCC. 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. Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
Zhengzhou's late-August subtropical monsoon climate typically produces daily maximum temperatures of 30–33°C under the influence of the East Asian summer monsoon and regional heat buildup, consistent with long-term station records showing mean highs near 31°C and frequent exceedances above 32°C. Current model consensus from regional forecasting centers anticipates partly cloudy conditions with limited cloud cover and minimal cooling from scattered thunderstorms on the 21st, keeping surface heating dominant and supporting trader consensus for the 32°C-or-higher outcome. Only an unexpected surge in organized convection or strong northeasterly flow could realistically cap the peak below this threshold, though historical analogs indicate such suppression is uncommon this time of year.
