Recent forecasts from the Hong Kong Observatory and supporting models indicate a minimum temperature near 27°C on August 30 amid persistent southwest flow and a broad low-pressure trough driving scattered showers and thunderstorms. High relative humidity (75–95%) combined with extensive cloud cover and overnight rainfall limits radiational cooling, keeping the overnight low tightly clustered around the 26–28°C range reflected in current market-implied odds. Minor differences among leading outcomes hinge on exact shower timing, localized wind shifts, and model spread in boundary-layer moisture, with any clearer intervals potentially allowing a dip toward 26°C while heavier or earlier rain could hold readings near 28°C. Updated HKO guidance and refined model runs overnight will likely narrow this uncertainty before resolution.
