Latest numerical weather prediction models and observational data from agencies like the China Meteorological Administration point to a daytime maximum near 32°C in Shanghai on August 29, driven by persistent subtropical high pressure, light southeasterly winds, and partly cloudy skies with only isolated shower chances that are unlikely to suppress peak heating. High humidity typical of late-August monsoon conditions will maintain elevated heat indices, while the urban heat island effect in the densely built city may nudge readings slightly higher than surrounding rural areas. Trader consensus reflected in the 60.5% implied probability for 32°C aligns closely with this forecast consensus, though minor model variations keep 31°C and 33°C as viable alternatives ahead of final observational verification.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Shanghai Pudong International Airport Station in degrees Celsius on 29 Aug '26.
The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=zspd
If NOAA data is unavailable or missing for the observation period, Weather Underground will be used as the secondary resolution source.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °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.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.Latest numerical weather prediction models and observational data from agencies like the China Meteorological Administration point to a daytime maximum near 32°C in Shanghai on August 29, driven by persistent subtropical high pressure, light southeasterly winds, and partly cloudy skies with only isolated shower chances that are unlikely to suppress peak heating.
