Recent official forecasts from the Hong Kong Observatory indicate a minimum temperature near 27°C on September 7 under mostly cloudy skies with isolated showers and light winds, consistent with late-summer patterns where overnight lows typically range 25–27°C amid high humidity. Cloud cover and scattered rainfall from lingering tropical moisture can limit radiative cooling, keeping minima from dropping toward the 22–24°C thresholds priced at lower probabilities, while any clearer spells or stronger northeasterly flow could allow modest cooling. Broader seasonal context includes an emerging El Niño contributing to above-normal warmth overall, though short-term model consensus shows limited day-to-day variability in the minimum ahead of the market close.
