Forecast models from authoritative sources indicate Guangzhou's overnight low on September 20 will likely settle near 27–28°C amid persistent subtropical warmth, high humidity near 60–80%, and light variable winds that limit radiative cooling. Recent observations show daytime peaks exceeding 35°C with minimal cloud cover early, transitioning to partly cloudy conditions and isolated showers that may slightly moderate but not sharply depress nighttime temperatures. This aligns with late-September climatology where average lows hover around 24°C yet current patterns reflect elevated baseline warmth without strong frontal intrusions or heavy precipitation. Market-implied odds cluster tightly around 26–28°C due to minor model divergences in dew point and wind forecasts, with resolution depending on official station minimums from the China Meteorological Administration. Updated guidance through evening hours will refine these 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.
