Recent forecast models from agencies like the China Meteorological Administration point to persistent cloud cover, high humidity, and scattered showers or thunderstorms over Guangzhou through August 4, which typically cap daytime heating and limit peak temperatures. Subtropical monsoon patterns and urban influences create narrow margins between 31–33 °C outcomes, with any earlier or more intense rainfall favoring the lower end while clearer breaks could push toward 33 °C. This genuine variability in short-term model runs explains the tight market clustering around those values, as traders weigh ensemble guidance against historical August baselines near 32–34 °C highs. Updated model runs and official briefings in the next 48 hours will likely refine the range.
