Trader sentiment for Guangzhou's August 28 maximum temperature remains evenly split across bins due to forecast uncertainty in convective activity two days ahead. Subtropical monsoon conditions, modulated by moist air from the South China Sea, favor scattered thunderstorms that can reduce solar insolation and cap daytime peaks near the 33°C climatological average. Model runs show variability in cloud cover and timing of rainfall, which directly influences whether surface heating reaches 32–34°C or allows brief clears pushing toward 35°C or higher. Urban heat island effects in the Pearl River Delta amplify sensitivity to these short-term changes, while weak steering winds limit rapid shifts. Updated regional model guidance expected within 24 hours will likely clarify resolution thresholds.

The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=zggg
If NOAA data is unavailable or missing for the observation period, Weather Underground will be used as the secondary 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.
