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 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 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.
Recent global and regional forecast models, including those from the China Meteorological Administration, point to a highest temperature in Chengdu on August 21 most likely between 31–33°C amid high humidity and scattered afternoon thunderstorms typical of the Sichuan Basin in late summer. These conditions create tight clustering around the leading market outcomes, as variable cloud cover and localized rainfall can suppress or allow brief peaks near 34°C. Historical August averages hover near 30–32°C with low probability of extremes below 30°C or above 35°C this late in the season. Updated model runs and official observations tomorrow will resolve the narrow uncertainty band.
