Current forecast models from agencies including the China Meteorological Administration and GFS ensembles indicate Shanghai’s overnight low on September 23 will likely settle near 23–24 °C under mostly cloudy skies and light easterly flow. Radiative cooling will be moderated by persistent cloud cover and urban heat-island effects typical of the Yangtze River Delta in late September, when climatological minimums average 22–24 °C. Trader consensus, reflected in the tight clustering around 23–24 °C outcomes, aligns with these consensus runs; wider spreads reflect model sensitivity to exact cloud timing and boundary-layer moisture. Updated high-resolution guidance expected within 24 hours will refine the precise minimum before market resolution.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Shanghai Pudong International Airport Station in degrees Celsius on 23 Sep '26.
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.Current forecast models from agencies including the China Meteorological Administration and GFS ensembles indicate Shanghai’s overnight low on September 23 will likely settle near 23–24 °C under mostly cloudy skies and light easterly flow.
