Forecast consensus from official models and agencies points to a Shanghai minimum of 27–28°C on August 23, driven by persistent southeasterly flow, high dew points near 25–27°C, and widespread cloud cover with scattered showers that limit nocturnal radiative cooling. These conditions, typical of late-summer East Asian monsoon patterns, have kept overnight lows elevated across recent days and align closely with the market’s leading outcomes. Updated numerical weather prediction runs show limited spread, with only minor steering variations that could nudge readings by 1°C. The China Meteorological Administration’s next 24-hour guidance, along with real-time station data, will provide the final verified minimum for resolution.

This market will resolve based on the lowest 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 lowest 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 lowest 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.
