Recent forecasts from the Hong Kong Observatory highlight a dry northeast monsoon advecting cooler continental air over the region, producing clear to partly cloudy skies and radiative cooling overnight that positions the October 7 minimum near 23°C in urban areas, with New Territories sites potentially 2–3°C lower. Model consensus and climatological normals for early October support this range, with limited cloud cover and moderate humidity reducing the chance of warmer overnight lows or sharper drops below 22°C. Trader emphasis on 23–24°C outcomes reflects these stable atmospheric conditions and the short two-day horizon to resolution, though any late shift in monsoon strength or local wind patterns could adjust final readings.
