Recent official forecasts and real-time observations for Shanghai on September 8, 2026, show a daily maximum near 30°C under partly cloudy skies with light northerly winds and moderate humidity. Multiple meteorological models converge on this value, consistent with late-summer climatology for the region where highs typically range 28–31°C absent strong frontal systems or heavy rainfall. Current surface readings approaching or reaching 29°C support the market-implied outcome. A notable increase in cloud cover or convective precipitation could cap temperatures below this threshold, while clearer conditions or delayed sea-breeze effects might push readings slightly higher; however, late-day stabilization reduces the likelihood of significant revision.

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 8 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.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
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 official forecasts and real-time observations for Shanghai on September 8, 2026, show a daily maximum near 30°C under partly cloudy skies with light northerly winds and moderate humidity.
