Recent forecasts from multiple meteorological services for Chengdu on October 1, 2026, indicate a daily high near 23–25°C under overcast skies, light variable winds, and moderate humidity in the Sichuan Basin. These conditions typically moderate daytime warming while limiting nocturnal cooling. Trader consensus heavily favoring 27°C at 81.5% implied probability likely reflects model runs emphasizing the upper end of the uncertainty range, historical October extremes, or expectations that official observatory readings (e.g., from the China Meteorological Administration) will register slightly above public point forecasts. Lower probabilities for 28°C+ or sub-26°C outcomes align with the narrow spread in current guidance and the absence of strong synoptic drivers for significant deviation. Updated model outputs and real-time observations near local noon will provide the clearest signals for resolution.
