Current forecast models from regional meteorological agencies indicate a high near 29°C for Shanghai on September 22, driven by partly cloudy skies allowing moderate solar heating and light northeasterly winds that limit cooling from advection. Recent observations show stable surface conditions with dew points around 19–22°C, supporting daytime maxima in the upper 20s without significant moisture influx or frontal activity. Ensemble guidance exhibits a narrow spread between 28–30°C, reflecting typical late-September climatology where average highs hover near 28°C but can edge higher under clear conditions. Traders appear to weigh the slight edge toward 29°C against potential under-forecasting from local urban heat effects or minor model adjustments ahead of the event.

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.
