Hong Kong records 17.5°C on coolest morning of autumn; warm-up ahead, highs of 29°C next week

Hong Kong recorded its coolest morning of the autumn so far on Tuesday (10 November), with the Observatory logging a minimum of 17.5°C as a northeast monsoon brought cooler weather and northerly winds to the city. Parts of the New Territories were cooler still. The cool spell is expected to be short-lived, with daytime highs forecast to return to 28°C to 29°C early next week.

Weak cold air behind the swings

Acting senior scientific officer Lam Hok-yin told a radio programme that the recent temperature swings could be related to the limited strength of cold air affecting southern China in autumn. Wednesday morning, 11 November, was expected to remain relatively cool, with temperatures around 18°C in urban areas and at least one or two degrees lower in the New Territories.
