Current ensemble forecasts from major global models indicate overnight lows for Guangzhou on September 8 centered in the mid-20s Celsius, driven by persistent high humidity, scattered convective rain, and variable cloud cover that moderates radiative cooling. Subtropical conditions with dew points near 24–25°C and light winds limit sharp temperature drops, while any clearer intervals could allow brief dips toward 24°C or below. Historical September averages near 24.7°C provide a baseline, yet model spreads and timing of precipitation introduce genuine uncertainty that keeps probabilities for 24°C, 25°C, and cooler outcomes tightly clustered. Updated runs from agencies like the China Meteorological Administration will clarify thresholds 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.
