Recent forecasts from multiple models indicate a highest temperature in Guangzhou on August 22 most likely between 31–34°C, driven by persistent subtropical monsoon moisture and scattered thunderstorms that promote cloud cover and reduce peak solar heating. Ensemble guidance shows modest uncertainty in the exact timing and coverage of convection, allowing a realistic path to 35–36°C if skies clear earlier in the day or if steering patterns limit rainfall. Persistent high humidity near 80% and typical August climatology (daily highs averaging 32–33°C) further anchor expectations, while any stronger afternoon storms would favor the lower end of the distribution. Updated short-range runs from the China Meteorological Administration and global models over the next 48 hours will refine these variables ahead of market resolution.
