Recent numerical weather prediction models, including outputs aligned with National Meteorological Center guidance, converge on a daily maximum temperature of 30–31°C for Shanghai on September 1, 2026, positioning these as the leading market outcomes. Easterly to southeasterly flow, elevated humidity near 80%, and scattered afternoon convection with 40% rain probability are expected to moderate peak heating while preventing significant cooling. Ensemble consensus shows limited spread around this range, consistent with early-September climatology of 28–30°C highs, though model updates on steering patterns or cloud cover could still shift the final observed value within the 29–32°C band.

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 numerical weather prediction models, including outputs aligned with National Meteorological Center guidance, converge on a daily maximum temperature of 30–31°C for Shanghai on September 1, 2026, positioning these as the leading market outcomes.
