Recent forecasts for Shanghai on August 12 indicate a high near 28–29°C under the lingering effects of Tropical Storm Dolphin, which brought heavy rainfall, strong winds, and extensive cloud cover to eastern China through August 10–11. These conditions suppress daytime heating compared with typical August maxima of 31–32°C by enhancing evaporative cooling and limiting solar radiation. Model consensus from sources such as timeanddate and AccuWeather supports this cooler regime, with isolated thunderstorms expected to maintain overcast skies. The market’s concentration on 28–29°C outcomes reflects traders weighting official observational trends and short-range model runs that show limited intensification potential before the system weakens. Updated guidance from the China Meteorological Administration on August 11 could further refine these probabilities ahead of the daily maximum measurement.

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 12 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.
