Recent ensemble forecasts from global models point to overnight lows in Shanghai around 22–23°C on September 20, driven by a shift to partly cloudy skies and light northerly winds that enhance radiative cooling after recent showers. Clearer conditions overnight allow greater heat loss from the surface compared to the more humid, overcast pattern earlier in the week, while modest advection of cooler air from the north limits daytime recovery and keeps minima competitive with historical late-September averages. Trader sentiment clusters tightly on 22–24°C because small differences in cloud cover or urban heat island effects can shift the exact minimum by 1°C, and fresh model updates or surface observations over the next 48 hours remain the key variables that could tilt resolution probabilities.

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 20 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.Recent ensemble forecasts from global models point to overnight lows in Shanghai around 22–23°C on September 20, driven by a shift to partly cloudy skies and light northerly winds that enhance radiative cooling after recent showers.
