Recent forecasts from meteorological agencies and models indicate Shanghai's overnight low on August 22 will likely settle near 27°C, driven by persistent easterly flow along the subtropical high's edge, elevated humidity near 90%, and scattered cloud cover or light rain that limits radiative cooling. This pattern matches recent observations where nighttime minima have held at 26–27°C amid similar moist, stable conditions. Stronger cooling would require clearer skies or a shift to drier northerly air, which current guidance does not support, while warmer readings remain possible if winds stay elevated or precipitation is minimal. Updated model runs and local observations through the evening of August 21 will refine the exact minimum before market 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 22 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.
