Recent forecasts from multiple meteorological sources converge on a maximum temperature of 31–32°C in Shanghai on August 28, reflecting the primary influence of persistent cloud cover, scattered showers, and moderate easterly winds tied to a nearby tropical system. These conditions limit solar heating and enhance mixing, capping daytime peaks below recent late-August averages near 33°C. Official guidance consistently lists highs in the 28–32°C range with light rain or overcast skies, aligning with trader emphasis on the 31°C and 32°C outcomes that together imply over 85% probability. Any shift would require clearer skies or stronger subsidence to push readings higher, though models show limited support for such changes before resolution.

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 28 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.Recent forecasts from multiple meteorological sources converge on a maximum temperature of 31–32°C in Shanghai on August 28, reflecting the primary influence of persistent cloud cover, scattered showers, and moderate easterly winds tied to a nearby tropical system.
