Persistent high-pressure aloft has maintained stable subtropical conditions over Hong Kong, limiting overnight radiative cooling and supporting a minimum temperature near 28°C on September 29. Official Hong Kong Observatory guidance and multiple forecast models project a daily range of 28–33°C under light southwest winds and low precipitation probability, consistent with late-September climatology where typical minima hover around 24–26°C but current warmth elevates the floor. Trader consensus at 99% implied probability for 28°C reflects this strong model agreement and absence of disruptive weather systems. A localized heavy downpour or unexpected wind shift could enhance evaporative cooling enough to dip briefly to 27°C or lower, though such outcomes remain low-probability given the entrenched anticyclonic regime.
