Current short-range forecasts for Chengdu point to scattered showers on August 6 moderating daytime heating in the Sichuan Basin, where surrounding mountains trap moisture and limit ventilation. This setup favors a maximum near 31°C under partly cloudy skies, though model spread on rain timing and coverage leaves room for 32–33°C if convection remains isolated or delayed. Historical August climatology shows typical highs of 30–34°C with frequent thundershowers that cap peaks through evaporative cooling and reduced solar insolation. Traders price 31–33°C outcomes highest because ensemble guidance clusters there, while probabilities decline sharply outside this range absent major forecast shifts before resolution.
