Vietnam in January: Weather by Region and Where to Go

January is one of the most rewarding months to travel in Vietnam, but the country is long and the weather changes a lot from north to south. The south is in the middle of its dry, sunny season, the centre is drying out after the autumn rains, and the north is cool, grey and atmospheric. Here is what to expect in each region, where January works best, and how to plan around the Lunar New Year.

A quick word on Tet in 2027

Tet, the Lunar New Year, falls on 6 February 2027. The weeks before it are a lovely time to be in Vietnam, with flower markets, red decorations and a festive mood in every town. The flip side is that flights, trains and buses fill up fast in late January and early February as millions of people travel home, and some family-run shops and restaurants close for several days around the holiday itself. If your trip touches the last week of January, book transport and hotels early.

Northern Vietnam: Hanoi, Ha Long Bay, Ninh Binh and Sapa

January is the coolest month in the north. In Hanoi, daytime temperatures usually sit somewhere around the mid to high teens Celsius, often under overcast skies with light drizzle, and evenings feel chilly because most buildings have no heating. It is a great month for wandering the Old Quarter, sitting in warm cafes with egg coffee and eating steaming bowls of pho without breaking a sweat.

• Ha Long Bay: cruises run all winter, but expect cool air, mist and lower visibility. The upside is a moody, quiet bay. Swimming is not really an option.

• Ninh Binh: soft light and fewer crowds make it a good day trip from Hanoi. Bring a jacket for the boat ride.

• Sapa: genuinely cold, with nights that can drop close to freezing and the occasional frost. The rice terraces are bare and brown at this time of year, so come for the mountain villages and trekking rather than green fields.

Central Vietnam: Hue, Da Nang and Hoi An

The heavy autumn rains are mostly over by January, but the central coast is still in its transition period. Expect a mix of cloudy days, showers and pleasant sunny spells, with temperatures that are comfortable for sightseeing. Hue tends to be the wettest of the three, while Hoi An and Da Nang usually get more dry days as the month goes on. The sea is on the cool and choppy side, so think of this as a culture and food trip rather than a beach holiday. February onwards is usually better if beaches are your priority.

South-central coast and the highlands: Nha Trang, Mui Ne and Da Lat

• Nha Trang: the rainy season usually finishes by the end of December, so January is generally drier, though early-month showers are still possible.

• Mui Ne: dry and very windy, which makes it one of the best months for kitesurfing.

• Da Lat: clear, sunny days and cold nights. Pack a warm layer for the evenings.

Southern Vietnam: Ho Chi Minh City, the Mekong Delta and Phu Quoc

This is where January shines. Ho Chi Minh City and the Mekong Delta are in the heart of the dry season, with plenty of sunshine, low humidity by local standards and daytime temperatures typically around 30 to 32 degrees Celsius. It is ideal for Mekong boat trips, the Cu Chi Tunnels and long evenings of street food in Saigon.

Phu Quoc is at its best right now. The west coast is calm, the water is clear and the sunsets are spectacular, which is why the island gets busy in January. Book beachfront hotels well in advance.

Where to go in January: a sample two-week route

• Days 1 to 3: Hanoi, with a day trip to Ninh Binh.

• Days 4 to 5: an overnight cruise in Ha Long Bay or Lan Ha Bay.

• Days 6 to 8: fly to Da Nang and base yourself in Hoi An, with a morning at My Son Sanctuary.

• Days 9 to 11: fly to Ho Chi Minh City, with a day in the Mekong Delta.

• Days 12 to 14: finish with sun and sea on Phu Quoc.

Travelling north to south like this means you start with the cool weather and finish on the beach, and it keeps you out of the worst of the central coast showers by the time you reach Hoi An.

Practical tips for a January trip

• Pack for two climates: a warm jacket and layers for the north, light clothes and sunscreen for the south.

• Book early around Tet: flights and trains in the last days of January and the first week of February sell out.

• Expect closures over Tet itself: big attractions and hotels stay open, but many small local businesses close for a few days.

If you are travelling with children or older parents, pre-booked airport pickups and day trips save a lot of energy. A private driver service such as COA-LIMO can handle the longer road journeys, like Hanoi to Ninh Binh or Saigon to the Mekong Delta, so you only have to think about where to have lunch.

Whatever route you choose, January rewards a little flexibility. Keep one or two loose days in the plan, follow the sunshine south if the north turns grey, and enjoy the build-up to Vietnam's biggest celebration of the year.
