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 Wuhan Tianhe International Airport Station in degrees Celsius on 23 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 Wuhan Tianhe International Airport Station, available here: https://www.wunderground.com/history/daily/cn/wuhan/ZHHH. 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.
Latest ensemble forecasts from regional and global models place Wuhan's August 23 daily maximum in the narrow 34–35°C range under typical late-summer Yangtze Valley conditions, driving the near-even market split between those two outcomes. Persistent high humidity, light winds, and potential for patchy afternoon cloud cover or weak convection introduce modest uncertainty in peak readings, consistent with historical late-August variability where daily highs often cluster between 33–36°C. Official monitoring by the China Meteorological Administration will resolve the market based on the verified maximum at the primary Wuhan station, with any late-model shifts in boundary-layer moisture or insolation likely to tip sentiment between the two leading brackets before resolution.
