Forecast consensus from official sources including the China Meteorological Administration centers on a daily maximum of 31–32°C at Shanghai Pudong International Airport for August 21, 2026, producing the market’s near-even split between those two outcomes. Easterly flow and light rain or showers are expected to limit insolation and cap temperatures near the lower end of the range, while scattered or broken cloud cover in some numerical model runs could permit brief afternoon peaks to 32°C. Historical August climatology shows typical highs near 31–32°C under similar synoptic patterns, and traders are weighting the latest short-range guidance against model spread on precipitation timing. Real-time surface observations throughout the day will determine the official peak used for resolution.

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 21 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.
