Recent forecasts from regional models and station data place Shanghai’s August 23 maximum near 31–32 °C, aligning with the market’s leading implied probabilities. Persistent cloud cover and scattered showers, remnants of earlier monsoon and typhoon activity, continue to limit insolation and cap daytime heating below mid-month peaks above 35 °C. Southeasterly flow off the East China Sea adds marine moderation while urban heat-island effects keep readings close to historical late-August normals of 31–32 °C. Updated model runs and official observations from the China Meteorological Administration in the next 24 hours will determine whether the high edges to 32 °C or settles at 31 °C.

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 23 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.
