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 Chengdu Shuangliu International Airport Station in degrees Celsius on 20 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 Chengdu Shuangliu International Airport Station, available here: https://www.wunderground.com/history/daily/cn/chengdu/ZUUU. 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 numerical weather prediction models for Chengdu show a narrow range of possible daily maxima around 29–32°C on August 20, driving tight market-implied odds clustered on 29–31°C. Chengdu’s subtropical monsoon setting within the Sichuan basin favors strong daytime heating under the Western Pacific Subtropical High, yet scattered afternoon convection and high humidity often cap peaks through reduced insolation and evaporative cooling. Minor differences among leading outcomes hinge on exact cloud cover timing, boundary-layer mixing, and any weak frontal influence, all of which remain uncertain within 24 hours of the observation window at the official Shuangliu station.
