Current model consensus from sources including the Global Forecast System points to a Shanghai minimum near 21–22°C on September 16 under northeasterly flow, stable high pressure around 1017–1018 hPa, and partly cloudy to overcast skies that limit nocturnal radiative cooling. This setup follows a modest cooling trend from recent days, with dew points in the mid-teens supporting gradual temperature drops after sunset but without strong cold advection. The closely matched market odds around the 17°C threshold versus warmer bins reflect genuine uncertainty in precise overnight minimums, as small shifts in cloud cover or wind speed can alter cooling rates by 1–2°C. Updated model runs and official observations over the next 48 hours will refine these inputs ahead of market resolution.

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.
