Recent forecasts from multiple models for Shanghai on September 22 point to a high near 29–30°C under partly cloudy skies and light northeast winds, supporting the tight market split between 28°C and 29°C. Persistent high pressure and moderate humidity around 55–65% favor gradual daytime warming without strong advection or precipitation to suppress temperatures. Subtle variations in predicted peak insolation and boundary-layer mixing explain the near-even odds, as official observations resolve to the nearest whole degree. With resolution in under 48 hours, traders are weighting the latest ensemble runs showing limited upside potential above 30°C absent clearer conditions.

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.
