January is a month of contrasts as Vietnam settles into its clearest seasonal divide: the north is cold and often grey, the south is deep into its dry season with reliable sunshine, and central Vietnam is emerging from its wettest period, though lingering showers are still possible. Tet preparations may begin building toward the end of the month depending on the lunar calendar.
Weather by Region
North (Hanoi, Ha Long, Sapa, Ninh Binh, Ha Giang, Mai Chau): Cold, dry, and often overcast, 10-18°C in Hanoi with damp, misty mornings; Sapa can approach freezing, especially at night.
Central (Hue, Da Nang, Hoi An, Nha Trang, Phong Nha, Quy Nhon, Da Lat): Tail end of the wet season, cooler and cloudier than peak summer, occasional rain lingering from the Oct-Nov peak; Da Lat stays cool and dry, 15-24°C.
South (Ho Chi Minh City, Mekong Delta, Phu Quoc, Mui Ne, Con Dao): Firmly in the dry season, hot and sunny with minimal rain, 25-34°C and comfortable humidity.
Where to Go in January
- Ho Chi Minh City, the Mekong Delta, and Phu Quoc for reliably dry, sunny days ideal for beaches and boat trips
- Mui Ne and Con Dao for calm seas and clear skies as the dry season firms up
- Da Lat for cool, crisp highland weather that’s pleasant year-round but especially fresh now
- Hoi An and Hue as rains ease, offering quieter streets before the spring crowds
Where to Avoid or Plan Around
Northern Vietnam is at its coldest and greyest this month — Hanoi and Sapa see limited sunshine and chilly, damp conditions, so pack accordingly or focus time further south. Central Vietnam can still see residual wet-season showers, so keep itineraries flexible.
Events & Festivals
Tet (Lunar New Year) typically falls in late January or February depending on the year — if travelling close to this period, expect transport and hotels to book up quickly, though flower markets and festive decorations make it a vivid time to be in the country.
Practical Tips for January
- Pack layers for the north (jacket, warm layers) but light, breathable clothing for the south
- Check the Tet dates for the year you’re travelling, as it can shift between January and February
- Book domestic flights and trains early if travelling around Tet
- Central Vietnam’s weather is transitional, so build a buffer day or two into coastal itineraries
