Current forecasts from multiple models indicate a minimum temperature in Guangzhou on September 7 of 25–26°C as the most probable outcome, aligning with the closely matched market odds around those levels and historical September averages near 24.8°C. Subtropical conditions, combined with moderate monsoon moisture and light variable winds, support overnight radiative cooling to the mid-20s, while scattered showers or increased cloud cover could limit drops toward 24°C. Model consensus shows limited spread, though small shifts in precipitation timing or northerly flow could differentiate exact readings. Updated runs from agencies like the China Meteorological Administration over the next 48 hours will refine these variables ahead of 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=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.
