Recent forecasts from multiple models indicate a daily minimum near 21–23°C for Chongqing on September 14, driven by increasing cloud cover and light rain associated with a passing weather system that reduces nocturnal radiative cooling. Subtropical humidity and light winds further moderate temperature drops, while model consensus on the exact timing and intensity of precipitation creates spread between outcomes above 25°C and those below 17°C. Traders weigh these variables against typical September baselines, where clear skies would allow greater cooling and higher uncertainty in short-range guidance keeps the 26°C-or-higher and 16°C-or-below brackets nearly tied. Updated model runs and official briefings over the next 48 hours will likely narrow the range.
