Recent official forecasts from Chinese meteorological sources highlight increased cloud cover, moderate rain, and thunderstorms expected over Guangzhou on August 4, which limit solar heating and favor peak temperatures in the 29–32°C range rather than the typical August average near 33–34°C. Ensemble models show modest uncertainty around steering patterns and precipitation timing that could allow brief clearing and a higher reading near 33°C or suppress it further with sustained overcast conditions. Historical analogs from similar late-summer monsoon-influenced days underscore how convective activity often caps daily maxima by 2–4°C below clear-sky potential. Traders appear to weigh the balance between these near-term guidance shifts and climatological baselines as new CMA updates and refined model runs approach resolution.
