Hong Kong in January

A dry month. After cold air arrives, a dry wind makes it chilly, so bring layers. Just before Lunar New Year, a flower and plant market is held in Victoria Park.

January was mild: 19°C by day, 15°C at night, the kind of range where you stop checking the thermometer. The gap between day and night was just 4°C, so it felt much the same around the clock. Rain was rare: 3 rain days on average. 3 of 20 years had a completely dry January, while 2016 reached 16 rain days.

Typhoons i No tropical storm passed within 300 km in this month over the last 20 years. Typhoons: April to December
