**Official forecasts from the Hong Kong Observatory place the expected minimum temperature for September 28 at 28°C within a 28–33°C daily range under mainly fine, very hot conditions driven by a persistent high-pressure ridge over southeast China.** Southwest winds of force 3–4 and low rain probability support limited overnight cooling, keeping the low near this level. Recent model consensus and current observations align closely with this outcome, though minor variations from localized cloud cover or urban heat effects could allow a 27°C reading. A distant tropical cyclone and the approaching northeast monsoon are not expected to influence conditions until later in the week, leaving the market-implied 60% probability on 28°C as the consensus view ahead of tomorrow’s official minimum reading.
