Recent observations and short-range forecasts from meteorological agencies show Shanghai under persistent cloud cover and intermittent showers on August 9, limiting daytime solar insolation and capping the maximum temperature near 28°C. This aligns with model consensus indicating suppressed heating from high relative humidity, reduced shortwave radiation, and regional steering patterns that favor overcast conditions rather than clear-sky maxima typical for early August. Traders assign near-certainty to the 28°C outcome because official station data and nowcasts have already ruled out significant afternoon warming. A rapid clearing of cloud decks or an unexpected shift in the subtropical ridge could allow temperatures to climb several degrees higher before sunset, though such a change remains unlikely given current atmospheric stability.

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 9 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.
