Vietnam in January, region by region
On this page
Vietnam in January splits the country in two more sharply than any other month. Saigon is dry and 28°C; Hanoi is grey, damp and cold enough to need a real jacket, and Sapa can freeze.
What is the weather like in Vietnam in January?
January in the north runs 13 to 17°C under low cloud, with drizzle that never quite becomes rain. Hanoi averages a high near 20°C and a low near 14°C, nights fall under 10°C, and humidity near 75 per cent makes the figures feel colder than they read.
The centre is still shedding the wet season. Hue and Hoi An get showers and grey days, the sea is rough, and the beaches are for walking rather than swimming.
The south is at its best. Ho Chi Minh City holds 26 to 28°C, the delta is dry, and the islands have their clearest water of the year.
| Region | January | What it means |
|---|---|---|
| North | 13–17°C, drizzle, fog | Jacket weather, poor visibility in the mountains |
| Sapa and the highlands | 3–10°C, frost some nights | Cold, and worth it for empty trails |
| Centre | Showers easing, rough sea | Cities yes, beaches no |
| South | 26–28°C, dry | Peak season, and it earns the name |
Where should you go in January?
South, and the further south the better. Phu Quoc and Con Dao are in their dry window, the Mekong Delta is easy travelling, and Ho Chi Minh City is warm without being punishing.
The north still works for cities and markets rather than for views. Hanoi in the cold is atmospheric, the mountain markets at Bac Ha run through the winter, and the crowds are thin.
What January does not suit is a trip built around the northern landscape. Cloud sits on Sapa and Ha Giang for days, and a pass with no view is a long cold ride.
What should you skip in January?
Central beaches, and any plan that depends on seeing the north from a height. The sea between Da Nang and Hue is cold and choppy, and the karst country is often inside a cloud.
Ha Long cruises still sail, and a grey bay is a different photograph from the one that sold the trip. Anybody going anyway should treat it as scenery in monochrome rather than a beach day.
Trekking in the far north is cold, wet underfoot and frequently fogged in. The trekking guide covers when those routes are at their best, which is not now.
How busy is January, and what does it cost?
The south is at its annual peak, and the islands are the sharp end of it. The first week carries the tail of the Christmas and New Year rush, and Phu Quoc resort prices stay high through the month.
Tet falls in late January in some years, which changes everything — fares triple, small businesses close and domestic travel surges. The Tet guide has the dates and what actually shuts.
The north is the cheap half of the country in January. Hotel rates in Hanoi, Sapa and Ninh Binh are at their lowest, and the trip cost guide shows what that is worth over a fortnight.
What is on in January?
The solar new year on 1 January is a public holiday, and the country takes one day. It is a smaller event than the lunar new year by a wide margin, which the public holidays guide sets out.
Preparations for Tet fill the last weeks of January whenever the lunar new year falls in early February. Hang Ma street in Hanoi turns red, kumquat trees appear on motorbikes, and the flower markets run at full volume.
In the north, January is also the quiet season for the ethnic markets, which trade weekly regardless of tourism and are better for it.
What should you pack for January?
Two wardrobes if the route crosses the country. A real jacket, long trousers and a warm layer for the north; light clothes and a swimsuit for the south; a rain shell for both.
The mistake is packing for the tropics because the country is tropical. January in Hanoi catches out more visitors than any other month, as the packing guide explains with the temperatures.
Add a scarf for the mountains and something with a hood for the drizzle. An umbrella is less use than a hood on a pavement full of parked scooters.
Is the sea swimmable in January?
In the south, yes. The water off Phu Quoc and Con Dao sits near 27°C and the sea is flat, which is why those islands charge their highest rates now.
In the centre, no. The swell is up, the water is cool and most beach clubs are closed or half-staffed.
In the north, the question does not arise. Nobody swims off Ha Long or Cat Ba in January, and the beaches guide sets out which coast works in which month.
So is January a good time to visit Vietnam?
Vietnam in January is the best month of the year for a southern trip. For a north-to-south run it is the hardest of the dry-season months, because half the route is grey.
The honest version: come in January for the delta, the islands and the cities, and accept that the mountains are a lottery. The best time to visit guide compares it with every other month.
FAQ
Is January a good time to visit Vietnam?
January is the best month of the year for the south and one of the weakest for the north. The delta and the islands are dry and warm, while Hanoi sits at 13 to 17°C under drizzle and the mountains are often inside cloud. A southern trip in January is excellent; a full north-to-south run is a compromise.
What is the weather like in Hanoi in January?
Cold and grey by Vietnamese standards: a high near 20°C, a low near 14°C, nights under 10°C and humidity around 75 per cent. Rain arrives as persistent drizzle rather than downpours, and fog sits on the lakes in the morning. It is jacket weather and it surprises most first-time visitors.
Is it raining in Ho Chi Minh City in January?
Barely. January is in the middle of the southern dry season, with daytime temperatures of 26 to 28°C and almost no rain. That reliability is why the south is at its annual peak in January and why island prices are at their highest.
Can you swim in Vietnam in January?
In the south, yes — the water off Phu Quoc and Con Dao is near 27°C and the sea is flat. In the centre the sea is cool and rough, and in the north nobody swims in January. The swimmable coast moves with the month rather than staying put.
Does Tet fall in January?
Sometimes. The lunar new year falls between late January and the middle of February and moves each year, so some Januaries carry it and others carry only the preparations. Check the date for your year before booking, because fares and closures change around it.
