Recent forecasts from global and regional models indicate a highest temperature near 30–31°C in Shanghai on September 1, driven by persistent southeasterly flow, high humidity near 70–80%, and scattered convection that limits full solar heating while keeping the boundary layer warm. Current surface observations show daytime maxima of 31–33°C under partly cloudy skies, consistent with late-summer monsoon conditions and no strong frontal passage or tropical cyclone influence in the western Pacific. Ensemble guidance shows limited spread, with only modest model disagreement on exact cloud cover and precipitation timing, supporting the market’s heavy weighting toward 30°C and 31°C outcomes ahead of final observational confirmation.

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 1 Sep '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 for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the 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 global and regional models indicate a highest temperature near 30–31°C in Shanghai on September 1, driven by persistent southeasterly flow, high humidity near 70–80%, and scattered convection that limits full solar heating while keeping the boundary layer warm.
