Current meteorological forecasts for Shanghai on September 10, 2026, consistently project an overnight low near 22°C, supported by observed conditions including moderate humidity levels around 70%, light northerly to northwesterly winds, and partial cloud cover that limits excessive radiative cooling. Multiple models align on daytime highs of 28–30°C transitioning to this minimum under stable high-pressure influence typical for early September in the region. The market’s overwhelming 96.5% implied probability on 22°C reflects this model consensus and recent observational data. Deviations toward 21°C or below would require stronger clear-sky radiative losses or a sharper wind shift, while persistent showers or increased cloud cover could hold the low closer to 23–24°C.

The resolution source for this market will be information from NOAA, specifically the lowest 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.
