Recent forecasts from regional models show Chongqing's overnight low on September 30 likely reaching 21–23°C amid widespread cloud cover, light rain, and light northerly winds that limit radiative cooling. These conditions align with the seasonal shift from summer monsoon patterns, where historical September minima average near 22°C. Trader consensus favoring 22°C at roughly 50% implied probability reflects this model agreement, while elevated odds on 18°C or below capture potential for stronger cooling if showers intensify overnight. Upcoming updates from agencies like the China Meteorological Administration will refine steering patterns and precipitation timing ahead of resolution.
