Official forecasts from the Hong Kong Observatory indicate a minimum temperature of 27°C on October 16 under a fresh easterly airstream, with sunny periods, humidity of 65-85%, and low rain probability. Trader consensus heavily favors 26°C as the recorded low, reflecting model runs that incorporate overnight radiative cooling under partly cloudy skies and recent regional observations showing minima near or slightly below 27°C. Light easterly winds of force 4-5 may limit mixing, while any evening cloud cover or brief showers could further suppress temperatures by a degree. Updated HKO guidance and overnight station readings ahead of market resolution remain the key near-term drivers.
