Traders see the highest temperature in Chengdu on August 22 clustered around 32–34 °C because short-range ensemble forecasts from global and regional models show a typical late-summer monsoon pattern with daytime highs in the low-to-mid 30s, modulated by variable cloud cover and weak steering flow over the Sichuan Basin. Slight differences among these outcomes hinge on whether afternoon convection develops enough to cap temperatures near 32 °C or whether clearer skies and stronger insolation push readings to 34 °C; historical August maxima in Chengdu average near 32–33 °C, so the narrow spread reflects genuine uncertainty in boundary-layer moisture and local terrain effects rather than a strong consensus for any single value. The next CMA and ECMWF model cycles, plus updated observations from local stations, will likely tighten the range before resolution.
