Forecast models from agencies like the China Meteorological Administration and international ensembles indicate a peak of 33–35°C in Guangzhou on August 28, driven by typical late-summer subtropical conditions with high humidity near 80–90%, light variable winds, and scattered convective clouds or showers that limit daytime heating. Recent model runs show slight warming potential if afternoon clearing occurs, supporting the narrow market edge for 35°C over 34°C, while stronger thunderstorm development or thicker cloud decks could cap readings at 34°C or below. Historical August averages near 33°C and ongoing regional moisture from monsoon patterns add uncertainty around exact maxima, with resolution depending on official station observations of the daily high.

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.
