Recent forecasts for Chengdu indicate a likely overnight low in the low-to-mid 20s Celsius on August 29, driven by persistent high humidity, widespread cloud cover, and scattered rainfall that limits nighttime radiative cooling under the influence of the East Asian monsoon. Multiple model runs show minimum temperatures clustering near 22–24°C, with slight variations tied to the timing and intensity of showers that could either enhance or suppress cooling depending on wind patterns and dew points remaining elevated around 20–23°C. Trader sentiment reflects this tight spread, as small shifts in precipitation forecasts or boundary-layer moisture from upstream systems could easily tip the exact low between 22°C and 25°C. Historical August climatology for the region supports typical lows near 23°C, underscoring how current conditions align with seasonal norms but carry short-term uncertainty ahead of final model updates.
