Recent clearance after tropical cyclone remnants and associated rainfall through September 3 has set up clearer skies and northeasterly flow over Wuhan, favoring moderate radiative cooling overnight on September 4. Official forecasts from multiple models converge on a low near 20–22°C under partly to mostly clear conditions, with historical early-September baselines around 21–23°C and limited model spread on minimum temperatures. Trader consensus across the 20–26°C outcomes reflects this narrow band of expected overnight readings, while lower-probability tails account for residual uncertainty in exact cloud cover, wind speeds, or localized cooling. Updated guidance from the China Meteorological Administration and global ensembles will refine the precise minimum before 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=zhhh
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.
