January is the coldest and driest month in Hong Kong with an average low temperature of 14.4°C (57.9°F). Average high temperatures are pleasant 18.3°C (64.9°F) accompanied by a few days of rain in the form of drizzle as the highs seldom rise above 21.1°C (70°F).
The daily sunshine drops to 5 hours due to cloudy skies, but a light sweater is sufficient to take care of the cold that rarely drops below 10°C (50°F) except during a cold wave. Extreme cold temperatures are unknown, and the authentic Chinese cuisine in downtown is an unbeatable dinner option in the cozy evenings.
Tourists from mainland China mainly prefer Hong Kong for the mild winter to celebrate the New Year and the Chinese New Year - it is, however, advisable to avoid the rush and peak season rates as a visit during the spring or autumn is more pleasant. Carry a light jacket to counter the drizzle and watch the symphony of lights, a spectacular show of lights and sounds that set the harbor alight every night!
