Recent model consensus for Guangzhou under subtropical monsoon flow supports a daytime maximum near 34–35°C, with scattered afternoon thunderstorms expected to curtail peak heating through reduced insolation and evaporative cooling. High boundary-layer moisture and urban heat-island effects from the Pearl River Delta sustain the central tendency while limiting excursions above 36°C, which would require suppressed convection and clearer skies. Ensemble guidance clusters outcomes tightly because typical August instability—driven by strong solar angles and regional moisture—produces modest variability of 1–2°C. Updated short-range forecasts and real-time observations will refine trader positioning ahead of the daily maximum.

This market will resolve based on the highest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section.
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 18 Aug '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.
