Recent forecasts from Chinese meteorological sources and international models indicate a frontal system bringing clouds and scattered rain to Beijing on September 26, with daytime highs near 25–28°C but overnight lows potentially dipping toward 17–20°C depending on timing of precipitation and wind shifts. This creates substantial uncertainty in the daily minimum, as increased cloud cover and moisture can suppress radiative cooling while variable steering flows influence exact arrival of cooler air. Trader sentiment reflects this model spread, balancing elevated odds for sub-14°C readings against warmer scenarios above 22°C, consistent with typical late-September variability where small changes in boundary-layer conditions alter the low by several degrees. Updated runs from the China Meteorological Administration and global ensembles will likely refine the minimum before resolution.
