Forecast models from agencies including the China Meteorological Administration indicate a high of 27–30°C for Chengdu on August 29 amid increasing cloud cover, scattered thunderstorms, and moderate northerly winds that limit daytime heating. Persistent humidity above 70% and expected rainfall—following the end of the “dog days” period—suppress peak temperatures relative to mid-August readings that reached 34–39°C. Model consensus highlights variability in storm timing and intensity as the main source of uncertainty, producing closely matched market-implied probabilities for 28°C, 29°C, and 30°C. Historical late-August baselines for the Sichuan Basin average near 29–31°C, but current steering patterns favor earlier convective cooling. Updated numerical weather prediction runs and official briefings on precipitation amounts will likely refine these ranges ahead of resolution.
