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 Shanghai Pudong 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 Shanghai Pudong International Airport Station, available here: https://www.wunderground.com/history/daily/cn/shanghai/ZSPD. 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 meteorological forecasts for Shanghai point to persistent cloud cover and scattered showers or thundershowers on August 21, which are expected to limit daytime solar heating and cap the maximum temperature near 30–32°C. These conditions align with typical late-August patterns in the region, where high humidity and monsoon influences often suppress peaks below seasonal averages of 32–35°C. Trader consensus, with 31°C at 49% implied probability and 30°C at 28.5%, reflects model agreement on modest cooling from recent days' clearer skies and highs near 33°C, while lower odds for 32°C or above account for residual uncertainty in exact rainfall timing and intensity ahead of final observational data from Chinese meteorological agencies.
