Widespread cloud cover and thunderstorms driven by a broad low-pressure trough across southern China are expected to limit solar heating and suppress the daily maximum in Guangzhou on August 30. Official guidance and ensemble models point to highs of 30–32 °C amid 80–95 % rain chances, light variable winds, and high humidity that reduces diurnal temperature range. Recent days reached 34–35 °C under clearer conditions, but the shift to unsettled monsoon flow has already cooled the outlook by several degrees. Trader consensus reflected in the closely matched 31–33 °C probabilities aligns with this forecast consensus while leaving room for model adjustments on exact storm timing or intensity.

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 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.
