Vietnam in December, region by region
On this page
Vietnam in December is the southern dry season at full strength and the northern winter arriving. The last two weeks carry the Christmas and New Year peak, which lands hardest on the islands.
What is the weather like in Vietnam in December?
December in the south is dry and warm, with daytime temperatures around 26 to 30°C and cooler evenings than any other month — Ho Chi Minh City averages about 26°C, its coolest of the year.
The north is cold and often grey, with the mountains dropping close to freezing at night and Sapa seeing frost.
The centre is shedding the last of the wet season: showers easing, sea still rough, cities perfectly visitable.
| Region | December | What it means |
|---|---|---|
| North | Cold, 15–20°C, grey spells | Jacket weather, thin crowds |
| Sapa and the highlands | 3–10°C, frost, occasional snow | Cold, clear on good days |
| Centre | Showers easing, rough sea | Cities yes, beaches no |
| South | 26–30°C, dry | Peak season and peak prices |
Where should you go in December?
Go south for the weather and north for the atmosphere. Phu Quoc, Con Dao and the Mekong Delta are at their best, and Ho Chi Minh City is warm without the April heat.
The northern mountains are cold and clear on a good day, and Sapa in December has frost, empty trails and occasional snow.
The centre is a city month: Hue and Hoi An work well for walking, food and the old town, with the beach written off until spring.
What should you skip in December?
Skip the islands over Christmas and New Year unless it is booked. Phu Quoc is the sharpest peak in the country over those two weeks, and prices double or worse.
Avoid a northern trip built around views. December cloud sits on Ha Long and the mountains for days at a time, and the Ha Giang page is clear about what that does to the ride.
Central beaches are out, and the sea stays rough into January.
How busy is December, and what does it cost?
December is quiet until about the twentieth and then it is the most expensive fortnight of the year in the south. Christmas and New Year fill the islands and the coastal resorts, and rates roughly double.
The north stays cheap, because nobody is choosing Hanoi in the cold, and the centre is at shoulder prices as the rain eases.
Booking the southern islands late in December is the single most expensive mistake available on the Vietnamese calendar, which the trip cost guide prices out.
What is on in December?
Christmas is not a public holiday, and 25 December is a normal working day. Ho Chi Minh City decorates heavily, the Catholic districts fill on Christmas Eve, and the shopping streets are lit through the month.
New Year's Eve is marked in the cities, and 1 January is the public holiday that follows.
Tet preparations begin in late December in years when the lunar new year falls in January, which the Tet guide covers.
What should you pack for December?
Pack two wardrobes again. A real jacket, long trousers and a warm layer for the north; light clothes and swimwear for the south; a shell for the centre.
Sapa in December needs proper cold-weather kit rather than a fleece, because the temperature runs 3 to 10°C and the wind is worse than the number.
The packing guide sets out the split in detail, and December is the month it matters most.
Is the sea swimmable in December?
The southern sea is warm and calm, and the islands are at their best all month. The centre is rough and cool, and the north is out of the question until spring.
December has the same swimmable map as January: everything below Nha Trang works, and nothing above it does. The beaches guide has the month-by-month version.
So is December a good time to visit Vietnam?
Vietnam in December is excellent for a southern trip and mixed for a full-country one. The south is dry and warm, the north is cold and grey, and the centre is a city month rather than a coast one.
Book the Christmas fortnight early or travel in the first three weeks, when the same weather costs half as much. The best time to visit guide puts December against January, which is the same trip without the holiday peak.
FAQ
Is December a good time to visit Vietnam?
December is excellent for the south, where the dry season is at full strength and the islands are at their best, and cold and grey in the north. The centre works as a city month rather than a beach one. The last two weeks carry the Christmas peak and the highest prices of the year.
What is the weather like in Vietnam in December?
The south sits at 26 to 30°C and dry, the north at 15 to 20°C with grey spells, and the mountains at 3 to 10°C with frost and occasional snow. Ho Chi Minh City averages about 26°C in December, its coolest month, which is why the south is at its peak.
Is Christmas a public holiday in Vietnam?
No. 25 December is a normal working day, though Ho Chi Minh City decorates heavily and the Catholic districts fill on Christmas Eve. The public holiday nearby is 1 January, and it lasts one day.
How expensive is Vietnam at Christmas?
The two weeks from about 20 December are the most expensive of the year in the south. Phu Quoc and the coastal resorts roughly double their rates and sell out, while the north stays cheap because few visitors want Hanoi in the cold.
Can you swim in Vietnam in December?
In the south, yes — the sea around Phu Quoc and Con Dao is warm and calm all month. The central coast is rough and cool and the north is out until about May, which gives December the same swimmable map as January.
