**Forecast consensus points to a lowest temperature of 23–24°C on September 4 in Guangzhou, with market-implied probabilities clustered tightly around these outcomes amid typical early-September variability.** Official and model guidance from sources including WeatherBug, LUFT, and Yr show overnight lows of 22–24°C under mostly cloudy skies and light northwest winds, with dew points near 20–23°C limiting radiational cooling. Daytime highs are projected near 27–28°C with scattered showers (20–40% chance), which sustain cloud cover and moderate temperature drops. Historical climatology for early September places average lows near 24–25°C, but recent model runs indicate slightly cooler readings due to increased moisture and reduced insolation. Resolution hinges on the precise minimum recorded at official stations overnight into the morning of September 4; any clearer skies or stronger winds could push the low toward 22°C or below, while persistent clouds favor the higher end of the 23–24°C range.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Guangzhou Baiyun International Airport Station in degrees Celsius on 4 Sep '26.
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.**Forecast consensus points to a lowest temperature of 23–24°C on September 4 in Guangzhou, with market-implied probabilities clustered tightly around these outcomes amid typical early-September variability.**
