Recent forecast models from sources like the China Meteorological Administration and international ensembles point to Guangzhou experiencing partly cloudy to overcast conditions with scattered thunderstorms on July 20, keeping peak temperatures clustered around 32–34 °C under the influence of the East Asian monsoon trough and subtropical ridge positioning. High humidity (typically 70–80 %) and frequent afternoon convection limit insolation and evaporative cooling, narrowing the range between 32 °C (favored if storms develop early) and 34 °C (possible under brief clear spells). Historical July maxima average near 33 °C, but daily variability from steering flow and moisture convergence creates the tight market spread, with lower outcomes (≤31 °C) requiring stronger or more persistent rainfall that current guidance does not strongly support. Updated model runs and official briefings through July 19 will refine timing of any convective activity ahead of market resolution.

This market will resolve to the temperature range that contains the highest temperature recorded at the Guangzhou Baiyun International Airport Station in degrees Celsius on 20 Jul '26.
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Guangzhou Baiyun International Airport Station, available here: https://www.wunderground.com/history/daily/cn/guangzhou/ZGGG.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °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 forecast models from sources like the China Meteorological Administration and international ensembles point to Guangzhou experiencing partly cloudy to overcast conditions with scattered thunderstorms on July 20, keeping peak temperatures clustered around 32–34 °C under the influence of the East Asian monsoon trough and subtropical ridge positioning.
