Recent forecasts for Chengdu point to scattered showers and cloud cover on July 31 moderating daytime heating, with official guidance centering maximum temperatures near 27°C at the Shuangliu station. This aligns with the tight clustering of market-implied probabilities around 27–28°C. Key scientific variables include the strength and timing of monsoon-driven moisture influx, which increases low-level cloud fraction and reduces incoming solar radiation; subtle shifts in steering flow from the subtropical ridge that alter peak insolation windows by a few hours; and boundary-layer humidity amplifying or suppressing the diurnal temperature range. Model spread between ensembles, particularly in precipitation onset, accounts for the modest probability assigned to 29–30°C outcomes. Updated runs from global models over the next 48 hours will likely refine these odds ahead of resolution.
