Traders assign the highest probabilities to minimum temperatures of 26–27°C on August 27, reflecting Hong Kong Observatory and model consensus for overnight lows near 26–28°C amid scattered showers and humid monsoon flow. Persistent cloud cover and elevated moisture limit nocturnal radiative cooling, while light southerly winds and typical urban heat-island effects keep readings from dropping further. Seasonal outlooks indicate normal to above-normal temperatures through late August, consistent with historical averages around 26–27°C for the period, though small variations in shower timing or wind could shift the exact minimum by 1–2°C. Updated HKO forecasts and observational data in the next 48 hours will refine these probabilities before resolution.
