Forecast models from agencies including the China Meteorological Administration show Guangzhou's August 29 high clustered near 35–37 °C under lingering monsoon moisture and scattered convection. Variable cloud cover and thunderstorm timing create the tight market spread between 35 °C and 38 °C, as afternoon heating competes with rain-cooled boundary layers. Recent heavy rainfall on August 27 has elevated soil moisture, which may temper peak temperatures unless stronger subsidence develops. Updated ECMWF and GFS runs over the next 48 hours, plus official CMA guidance, will likely shift implied probabilities as steering patterns and instability indices evolve.

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.
