Temperature in Hong Kong in December

The 6°C day-night temperature range is typical for continental climates: a light jacket in the morning that you shed by midday and need again after sunset. At 78% humidity, the 20°C daytime high feels 2-4°C warmer in practice: quick-dry fabrics and shade-seeking between noon and 3pm are the sensible response. The UV index of 3 is low, meaning sun exposure is minimal concern and sunscreen is largely optional. Wind averages 18 km/h, light enough to be refreshing on warm days but noticeable in open coastal areas or elevated viewpoints. In Fahrenheit: 68°F average high, 57°F overnight low.

Packing for Hong Kong in December means dressing for 20°C days and 14°C evenings. A light cotton tee with a casual overshirt works well at 20°C, the overshirt doubles as a layer for air-conditioned venues. Evening temperatures settle at 14°C, a modest 6°C drop that a light cardigan or denim jacket covers. Comfortable walking trainers are the versatile choice for both outdoor sightseeing and indoor venues. At 78% average humidity, quick-dry synthetic or bamboo fabrics dry overnight and stay comfortable longer than cotton.

💡

Local tip: Temple and religious site visits require covered shoulders and knees in most of Hong Kong's heritage areas. A lightweight scarf or sarong weighs almost nothing and solves the problem instantly.
