Recent forecasts from the China Meteorological Administration and global models cluster Zhengzhou’s August 21 maximum near 30–32 °C under late-summer monsoon flow, with scattered showers and increasing cloud cover expected to cap afternoon heating. This keeps the market-implied odds tightly split between 31 °C (48 %) and 32 °C or higher (39.5 %), reflecting modest uncertainty in convective timing and boundary-layer moisture. Historical August averages of 32–33 °C provide context, yet a slight seasonal decline and potential for earlier rain onset tilt probabilities toward the lower side of that range. Traders monitor updated CMA guidance and regional model runs through the morning for any shifts in expected peak solar insolation or storm coverage that could resolve the outcome.

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.
