Northeast monsoon influence has established drier northerly flow over Hong Kong, producing clear to partly cloudy skies and a forecast minimum of 25°C for October 5 according to Hong Kong Observatory guidance. This aligns with the market's strong 66.5% implied probability for 25°C as the daily low, while the 32% chance assigned to 24°C reflects residual model spread on overnight radiative cooling under light winds. Historical October minima average near 23–24°C, but the current setup's stable high-pressure ridge and reduced humidity limit further drops, with official observations expected to confirm the threshold by evening.
