Vietnam in January: Weather, Where to Go and What the Tet Season Changes

Why January is a month of the south, not the north

Vietnam stretches roughly 1,650 km from the Chinese border to the Mekong Delta, and in January those 1,650 km have almost nothing in common. The country has three weather systems, and in this month they point in three different directions. The north is in the middle of its cool, grey winter. The centre is at the end of its rainy season, with the sea still unsettled. The south is in the heart of its dry season, with blue skies and no winter at all.

That is why a single verdict for “Vietnam in January” would mislead you. The honest summary is that January is a month for the south and the islands: Ho Chi Minh City, the Mekong Delta and Phu Quoc are at their most comfortable, while the north is at its least photogenic. The centre sits in between and rewards travellers who go for culture and food rather than beaches.

The other fact that shapes the month is Tet, the lunar new year. It falls between late January and mid-February, on a different date every year, and it reorganises the whole country’s calendar for a week or more. Depending on the year, it may sit well after your trip, or it may swallow the last days of it. We come back to it below.

January weather at a glance

Region	Typical January weather	Verdict
North: Hanoi, Ha Long, Ninh Binh	Cool and grey, 13 to 20 °C in Hanoi, drizzle and low cloud	Fine for city culture, poor for cruises and views
North mountains: Sapa, Ha Giang	Cold, often misty, near freezing at times in Sapa	Hard going for treks and motorbike loops
Centre: Hue, Da Nang, Hoi An	End of the rainy season, cool, showers likely, sea often rough	Good for heritage and food, unreliable for beaches
Da Lat and the Central Highlands	Cool all year because of altitude, fresh mornings	Pleasant, as it is in any month
South: Ho Chi Minh City, Mekong Delta	Dry, sunny, 25 to 35 °C, little rain	Excellent
Islands: Phu Quoc, Con Dao	Dry season, calm seas	Excellent for beaches and snorkelling

These are ranges, not promises. A cold front can bring a few days of unusually chilly weather in the north, and a late shower can still catch you in the south, but the pattern above is what you should plan around.

The south in January: the reason to come

If you only have one region for this month, make it the south. The dry season runs roughly from December to April, and January sits comfortably inside it: the heat is real but not yet the punishing peak of March and April, and the short, heavy afternoon downpours of the wet season are gone.

Ho Chi Minh City

Ho Chi Minh City is the country’s largest city and economic centre, still widely called Saigon. It is not the capital, which is Hanoi. In January its dry streets are at their best for walking: District 1 with Ben Thanh Market, the Reunification Palace, the War Remnants Museum and the Central Post Office, then on to the Nguyen Hue walking street in the evening. The metro’s Line 1 from Ben Thanh to Suoi Tien, which opened in December 2024, makes the eastern edge easier to reach, though most visitors still rely on ride-hailing apps such as Grab, Be and Xanh SM.

Keep your phone away from the kerb. Bag and phone snatching from passing motorbikes is the most common real nuisance in the city, and it is easily avoided by carrying things on the side away from traffic.

One practical point: the Cu Chi Tunnels, about 60 to 70 km north-west of the city, are far more comfortable in January than in the humid months, because crawling through a narrow passage in 35 °C wet heat is a very different experience. If you want to arrive in style, there is even a half-day option that combines the tunnels with a luxury speedboat ride along the river.

The Mekong Delta

The Mekong Delta is at its easiest in the dry season. Canals are navigable, roads are dry, and the light is good for the orchards and waterways around My Tho, Ben Tre, Cai Be and Vinh Long. For a first visit, one or two nights are more rewarding than a rushed day trip, because the best moments are early and late: boats at first light, quiet canals at dusk.

Plan a night in Can Tho, about 170 km from Ho Chi Minh City, if you want the Cai Rang floating market. It trades at dawn, so the evening before is the time to be there, and the market is at Can Tho, not at My Tho. For something more atmospheric than a standard cruise, a small-boat option such as a kayak and boat trip in search of fireflies and wildlife works well in the dry months, when the channels are calm.

Mui Ne and Phan Thiet, with their sand dunes about 200 km north-east of the city on the coast, are often grouped with the delta on itineraries, but they are a separate area. January is a pleasant time for the dunes, with dry weather though the wind can be strong for kitesurfers and less pleasant for sunbathers.

Phu Quoc

Phu Quoc is Vietnam’s largest island, in the Gulf of Thailand off the Cambodian coast, and its best season runs roughly from November to April. January falls squarely in it: calm water on the west coast, clear days, and warm sea. It has its own international airport, so you can fly in directly or connect from Ho Chi Minh City in about an hour.

This is the month for a boat day. A typical outing takes you to several small islands in the south of Phu Quoc for snorkelling, lunch and beach time, and a well-run one such as the four-island snorkelling trip with a beach barbecue gives you the best of the sea at its calmest. Because January is popular, book hotels and flights early, and earlier still if your dates run close to Tet.

Con Dao, further out and reached by air or fast ferry only, is quieter and wilder, and is also good in the dry months for those who want a smaller, slower island.

The centre in January: wetter, cooler, still rewarding

Central Vietnam is where January needs honesty. The rainy season there runs roughly from September to December, with typhoons and floods most likely in October and November. By January the worst is usually behind it, but the weather does not suddenly become reliable. Expect cool days, grey skies, drizzle that comes and goes, and a sea that is often too rough for comfortable swimming.

For the right traveller, that is not a disaster. Hue suits cooler, softer weather better than almost anywhere else: walking the Imperial City, visiting the royal tombs of Tu Duc, Minh Mang and Khai Dinh and the Thien Mu Pagoda on the Perfume River are all more pleasant when it is not 35 °C. The imperial cooking, including bun bo Hue and banh beo, is also better with a little chill in the air. If you are staying in Da Nang, a guided option such as a full-day tour of the Hue Imperial City from Da Nang makes the trip over the Hai Van Pass easy to organise, though in rain or mist the pass views can disappoint.

Da Nang and Hoi An work too, provided you treat beach time as a bonus rather than the plan. Hoi An’s old town is a UNESCO World Heritage Site, and its lantern-lit lanes are lovely on a cool evening. The tailors are busy, and January is a sensible month to order something made while you eat cao lau and mi quang. Pack a light rain jacket, and keep an afternoon flexible so a shower does not ruin a day.

Nha Trang’s rains come later than those of Hue and Hoi An, roughly October to December, so January is generally a little more settled on that stretch of coast, though still not as dependable as the south. Da Lat, at roughly 1,500 m on the Lang Biang plateau, is cool all year, so January there feels like any other month: fresh mornings, pine-scented air and a good place to wear a sweater. See Da Lat if you want a break from the heat.

The north in January: what to expect, and what to skip

Northern Vietnam has four seasons, and January is the heart of winter. Hanoi runs about 13 to 20 °C, often under a low, white sky, with drizzle and a damp cold that gets into your clothes. It is not unpleasant for a city break: egg coffee and pho taste better in this weather, the Old Quarter is lively, and sights such as the Temple of Literature and the Imperial Citadel of Thang Long are quiet. But do not expect crisp, sunny winter days.

The real cost of January in the north falls on outdoor plans:

• Ha Long Bay and Lan Ha Bay: mist and low cloud are common, so the limestone karst can vanish into grey. A cruise is still possible, but the views are the reason people go, and January often takes them away. If you do go, choose a cruise with a comfortable, heated cabin, such as a five-star overnight cruise on Lan Ha Bay, and expect cold decks in the evening.
• Sapa and the northern mountains: very cold, sometimes close to freezing in Sapa, with fog that hides Fansipan and the valleys. Treks become damp, slippery and cold, and the rice terraces are bare, since they are green from about June and golden around September and October.
• The Ha Giang loop: cold, foggy mountain roads on a motorbike are tiring and more dangerous than in the dry autumn.
• Ninh Binh: a gentler option. Trang An and Tam Coc work in cool weather, but expect a muted palette rather than the bright green of summer.

If the north is a must, the best advice is to reserve it for autumn, when October and November are its best season. January is the month to see the cities, not the landscapes.

Tet: what it changes, without a fixed date

Tet is the lunar new year, and the most important holiday in the country. It falls between late January and mid-February, on a different date each year, so never rely on a date remembered from a previous trip. Depending on the year, it may arrive at the very end of your January trip, or it may fall in February and leave January untouched.

What changes around it is practical rather than mysterious:

• Businesses close: many shops, restaurants and small hotels shut for several days, and some for longer, as families return to their home villages.
• Transport is full: trains, buses and flights are heavily booked in the days before and after, and prices rise sharply. Booking late can mean no seat at all.
• Prices rise: hotels, tours and some transport cost more, especially in tourist destinations.
• The atmosphere changes: the cities empty and go quiet on the main days, then become festive, with flowers and decorations in the lead-up.

For a traveller, the sensible rule is simple. Check this year’s Tet dates before you fix any booking, and either finish your trip well before the holiday or deliberately plan around it. The full explanation, including how to enjoy it, lives in our guide to Tet in Vietnam, and the neighbouring month is covered in Vietnam in February.

A realistic January route: south first, then the centre

The most sensible way to use January is to start in the warm south and finish in the centre, with a flight rather than a long road or rail journey between them. Vietnam is far longer than it looks on a map: Hanoi to Ho Chi Minh City is about two hours by air or more than thirty hours on the Reunification Express, so a domestic flight is the logical choice. Our guide to domestic flights in Vietnam covers the main airlines and the practical details.

A relaxed ten to twelve days might look like this:

Days	Where	What to do
1 to 3	Ho Chi Minh City	District 1, the markets, a day at the Cu Chi Tunnels, evenings on Nguyen Hue
4 to 5	Mekong Delta and Can Tho	Boats and canals, dawn at the Cai Rang floating market
6 to 9	Phu Quoc	Beach time, a snorkelling boat day, sunsets on the west coast
10 to 12	Da Nang, Hoi An and Hue	Fly in from Ho Chi Minh City, then heritage, food and a day in Hue

Why this order? The sunniest, driest days go to the stops that need them most, and you finish in the centre when you are ready for slower, cultural sightseeing. A flight from Ho Chi Minh City or Phu Quoc to Da Nang saves a long day on the road and puts you close to Hoi An, which is about 45 minutes from the Da Nang airport.

If you have only a week, drop the centre and stay south; Southern Vietnam in one week gives a ready-made version. If you want to extend into the centre, keep it short and flexible, and avoid scheduling anything that depends on a clear sky.

If you prefer to see Vietnam’s culture and food rather than beaches, a very good option is a hands-on session such as a cooking tour in Hoi An, which includes a market visit and works well on a grey or showery day.

Practical tips for January

• Pack for two climates. Light, breathable clothing and sun protection for the south, plus a warm layer and a light rain jacket for the centre and the north. Our packing list has the detail.
• Book early. January is popular with travellers escaping northern winters, and Tet adds pressure on flights and hotels in the second half of the month.
• Check the rain. If you need a better picture of what rain means in the centre, our guide to the rainy season and typhoons explains how the pattern works.
• Carry some cash. Street food, markets and small cafés still prefer cash in dong; hotels, cruises and tours accept cards. At the time of writing in 2026, a euro is worth roughly 28,000 VND.
• Drink bottled or filtered water. Tap water is not drinkable anywhere in Vietnam.
• Check entry rules. Visa exemptions and e-visa rules depend on your nationality and change, so confirm them with the official immigration portal or your government’s travel advice before you book.

Is January the right month for you?

January is the right month if you want sun and beaches, if you are happy to concentrate on the south and perhaps the central coast, and if you can be flexible about the Tet holiday. It is the wrong month if your priorities are Ha Long Bay views, trekking in the northern mountains or the Ha Giang loop; those are far better in autumn.

For a wider comparison, see our guide to the best time to visit Vietnam, which sets each region against the calendar. If you only need a rule of thumb, here it is: in January, go south and fly.

Vietnam in January: your questions answered

Is January a good month for Vietnam as a whole?

Not for the whole country at once. It is an excellent month for the south and islands such as Phu Quoc, an unsettled one for the centre, and a cool, grey one for the north. Build the trip around the south and the central coast rather than trying to cover Hanoi, Ha Long and Sapa as well.

How cold does it get in Hanoi and Sapa in January?

Hanoi usually sits between 13 and 20 °C with grey skies and drizzle, which feels colder than the number suggests because most buildings are unheated. In the mountains around Sapa it is much colder, and temperatures can come close to freezing, so bring proper layers if you go.

Is it the rainy season in central Vietnam in January?

The central rainy season runs roughly from September to December, so January is its tail end. Rain is less likely than in October and November, but showers, cool spells and rough seas are still common around Hue, Da Nang and Hoi An. Treat it as a month for culture and food rather than beach days.

When is Tet and how does it affect a January trip?

Tet follows the lunar calendar and falls between late January and mid-February, on a different date each year. In the days around it many shops and restaurants close, trains, buses and flights are fully booked, and prices rise. If your dates are close to it, read the dedicated Tet guide and book transport early.

Is Phu Quoc good in January?

Yes. Phu Quoc’s best season runs roughly from November to April, so January brings calm seas, sunshine and good snorkelling conditions. It is also popular, so book flights and beachfront hotels well ahead, especially near the Tet holiday.

Should I fly or take the train between regions in January?

Fly. Vietnam is about 1,650 km long, and the Reunification Express takes more than thirty hours from Hanoi to Saigon. A domestic flight is under two hours between the main cities, which leaves more of a short holiday for the places you actually came to see.

What should I pack for January in Vietnam?

Pack for two climates: light, breathable clothes and sun protection for the south, plus a warm layer and a light rain jacket for Hue, Da Nang and any northern stop. Bring an adapter if you come from the UK or US, since sockets are mainly Type A and Type C.
