Recent forecasts for Guangzhou show widespread rain and thunderstorms expected on August 31 amid ongoing monsoon influences and elevated humidity, which are likely to moderate temperatures through increased cloud cover, evaporative cooling, and northerly wind advection of slightly cooler air. Official model runs and historical climatology place typical late-August overnight lows near 25°C, with recent days featuring similar convective activity and daytime highs in the low 30s°C that have suppressed extremes. The closely matched market-implied odds for 25°C versus 26°C reflect uncertainty in precise radiative cooling rates under varying cloud thickness and precipitation timing, as well as minor model disagreements on boundary-layer moisture and wind shifts that could nudge the minimum by 1°C. Updated guidance from agencies like the China Meteorological Administration will clarify these variables ahead of resolution.

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 31 Aug '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.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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.Recent forecasts for Guangzhou show widespread rain and thunderstorms expected on August 31 amid ongoing monsoon influences and elevated humidity, which are likely to moderate temperatures through increased cloud cover, evaporative cooling, and northerly wind advection of slightly cooler air.
