Recent official forecasts from the Chengdu Meteorological Bureau and international models indicate a high of 31–33°C for August 28 amid increasing cloud cover and scattered to moderate rain, including afternoon thunderstorms. These conditions reduce incoming solar radiation and enhance evaporative cooling, limiting daytime heating compared to the recent 35–39°C peaks. Variability in rainfall timing, intensity, and localized convection introduces the main uncertainty, potentially shifting the maximum by 2–4°C depending on whether storms develop early or late. Traders weigh historical August baselines near 31°C against current model consensus showing suppressed highs from monsoon moisture and frontal influences.
