December is the least humid month of the year at 68% with mostly clear skies, and transitions to the mild winter with a gradual drop in temperatures. Average high temperatures are mild 20°C (68°F), while average low temperatures drop to a comfortable 15.6°C (60.1°F).
The sun is visible in its full splendor for 6 hours a day as the days become short and the nights are prone to cool temperatures. The winter sun, with an ultraviolet index of 7 suggests precautionary measures during outdoor explorations.
Be warned that early morning photography is a little tricky with the presence of fog, especially at high altitudes like the Victoria Peak for a spectacular view of the skyscrapers, the glittering harbor and the green terrain of the far-off New Territories.
Rain is of little consequence in December, but it never hurts to carry warm clothes and protective rain gear as Hong Kong weather is never truly dry.
