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 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 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 consensus forecasts from sources including the China Meteorological Administration and international models indicate Shanghai will reach a daily maximum near 31°C under partly cloudy conditions with scattered showers, southeast winds of 15–25 km/h, and high humidity around 70–80%. This aligns with typical late-August climatology, where afternoon peaks often occur between 30–32°C amid monsoon influences and urban heat effects. Trader consensus at 99.9% implied probability for 31°C reflects this strong model agreement and ongoing observations showing temperatures climbing through the low 30s. Realistically, localized variations at official stations, heavier afternoon convection, or timing shifts in cloud cover could push the verified high to 30°C or 32°C, though current data make substantial deviations unlikely.
