Current ensemble forecasts for Guangzhou on September 22 point to an overnight low near 26–27°C, supported by high humidity, extensive cloud cover, and scattered showers that limit radiative cooling under subtropical conditions. Persistent southerly flow and monsoon remnants maintain elevated dew points, while urban heat effects in the Pearl River Delta further buffer against sharp drops. Model consensus shows limited potential for either strong cold advection that could push minima to 21°C or below or clear, calm nights allowing lows near or above 31°C. Updated runs over the next 48 hours will refine the exact minimum, particularly regarding rain timing and wind speeds that directly influence the resolution thresholds.

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=zggg
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.
