Recent forecast models from the Hong Kong Observatory and global ensembles indicate the October 6 overnight minimum will likely settle in the low 20s Celsius, driven by northeasterly monsoon flow advecting cooler, drier air over the region following recent rainfall. Clear to partly cloudy skies overnight will enhance radiative cooling from the surface, while light winds limit mixing and allow temperatures to drop toward 21–23 °C. Historical October averages near 23 °C provide context, but the current setup favors the lower end of the typical range. Updated model runs tonight and early-morning observations will refine the exact minimum before market resolution.
