Vietnam in December: Cool and Grey in the North, Dry and Sunny in the South

One country, three different Decembers

Vietnam stretches roughly 1,650 km from the Chinese border to the Mekong Delta, and in December that length matters more than in any other month. In Hanoi you wear a jumper and watch the sky stay pale grey for days. A two-hour flight south, in Ho Chi Minh City, you sweat through a hot, dry afternoon in a T-shirt and the evening air is warm enough for a rooftop drink. The two cities are about 1,100 km apart as the crow flies, and the weather could belong to different countries.

That contrast is the real story of the month. December is the first month of the northern winter, the tail end of the rains along the central coast, and the opening stretch of the southern dry season. There is no single answer to “is December a good month for Vietnam”, so this guide gives you one for each region, then helps you decide who should aim south and who can happily accept the north in winter.

If you are still choosing between months, the wider picture is in our best time to visit Vietnam guide, and the month before this one is covered in Vietnam in November.

December at a glance

Region	What December feels like	Verdict
North (Hanoi, Ha Long, Ninh Binh, Sapa, Ha Giang)	Cool, grey, often damp; cold in the mountains	Good for culture and food, weak for scenery
Centre (Hue, Da Nang, Hoi An, Nha Trang)	End of the rainy season; showers, swell, cloud	Mixed, improving through the month
Da Lat and the Highlands	Cool, fresh, usually dry-ish days	Pleasant
South (Ho Chi Minh City, Mekong Delta, Phu Quoc, Con Dao)	Dry season, 25 to 35 °C, sunny	Excellent

The north in December: winter begins

December opens the northern winter, which runs from December to February. In Hanoi expect roughly 13 to 20 °C, a low, pale sky and a fine dampness that gets into everything. It is not freezing, but because many homes, cafés and hotel rooms are not heated, the cold feels sharper than the thermometer suggests. Locals wear padded jackets and scarves, and you will see them in the street on a day that a visitor from northern Europe would call mild.

None of that makes Hanoi unattractive. A grey winter day suits the Old Quarter very well: bowls of pho taste better in the cold, egg coffee is at its best, and the lanes around Hoan Kiem Lake are far less sweaty than in summer. The Temple of Literature, the Imperial Citadel of Thang Long and the Ho Chi Minh Mausoleum area are all comfortable for long walks. If food is why you are going, a guided evening is a good use of a cool night, and a private street food walk through Hanoi’s Old Quarter is an easy way to get past the menus you cannot read.

Ha Long Bay and Lan Ha Bay in winter

Do not expect the sunny turquoise postcard. In December the bay is usually misty or overcast, the water looks grey-green and the limestone islands appear as soft silhouettes. Many visitors find that atmospheric, and the upside is real: there is no typhoon season to worry about, the sea is generally calm and the crowds are thinner than in autumn.

You will, however, be on a boat in cool air, so bring a windproof layer for the deck, and choose a cruise with a heated cabin. Lan Ha Bay, off Cat Ba Island, is quieter than the classic Ha Long route, and an overnight such as a five-star overnight cruise in Lan Ha Bay from Hanoi gives you the calm water and the empty feeling of the karst without the traffic. Our comparison of Ha Long Bay or Lan Ha Bay explains the difference in more detail.

Ninh Binh

Ninh Binh, roughly 100 km south of Hanoi, is a good winter choice. Trang An and Tam Coc are best on a still, grey day with little wind, and the rice fields around them are bare after the harvest, so the scenery is subtler than in the green or golden months. Bring a jacket for the boat rides. It pairs well with Hanoi as a one-night break.

Sapa and the mountains

The northern mountains are where December bites. Sapa, below Fansipan, is often shrouded in fog and cloud, with cold nights that can fall close to freezing and occasional frost on the high ground. Views can open for an hour and close again, so a trek is a gamble. Mu Cang Chai’s terraces were golden in September and October and are now harvested and bare.

The Ha Giang loop is still rideable, but mornings are cold and wet on a motorbike, and the pass roads can be slippery. If you want mountains in December, accept the cold, pack real warm clothing and give yourself a spare day. Read Sapa and Ha Giang before committing, and consider whether autumn would suit you better.

The centre in December: the end of the rains

The central coast has a rainy season that runs roughly from September to December, with typhoons and floods most likely in October and November. By December the worst is usually over, but the transition is not sharp: expect a month of showers, cloud, a rough sea and some days when the sun does not appear at all. Hoi An’s old town floods in some years, so check conditions before travelling. Our guide to Vietnam’s rainy season and typhoons explains how to read the forecast.

Nha Trang is on the same pattern, with its rains arriving a little later than Hue and Da Nang, roughly October to December, so early December there can still be wet and swell-affected, and its snorkelling boats may be cancelled. Da Lat, at roughly 1,500 m on the Lang Biang plateau, is cool all year and usually pleasant in December, with fresh mornings and sweater evenings.

What works in the centre

Rainy-season weather does not ruin everything. Hue is arguably more atmospheric in grey weather, and the Imperial City, the royal tombs and Thien Mu Pagoda suit a day of drizzle better than a day of fierce sun. A full-day trip to the Imperial City of Hue from Da Nang works if you have a base on the coast. Hoi An is lovely for tailors, cooking classes and lantern-lit evenings, but beach days at An Bang are a gamble. The Hai Van Pass can be misty, and the coast road between Hue and Da Nang is much less scenic in poor visibility.

If you can only visit the centre in December, plan your days around indoor activities and treat sunshine as a bonus. If you have flexibility, shift your centre time to spring or summer, and use December for the south.

The south in December: the dry season arrives

This is the reason to travel in the month. The south has two seasons rather than four: a wet season roughly from May to November and a dry season roughly from December to April. It is tropical all year at 25 to 35 °C, with no winter. In December the afternoon downpours of the wet months have largely stopped, humidity is lower than in the summer, the sky is blue and the nights are pleasant. The hottest weather comes later, in March and April.

Ho Chi Minh City

Ho Chi Minh City is at its most comfortable in December. You can walk around District 1 from Ben Thanh Market to the Reunification Palace and the War Remnants Museum without being caught by a storm, and the rooftop bars and the Nguyen Hue walking street are at their best. For a half-day outside the centre, the Cu Chi Tunnels, roughly 60 to 70 km north-west, are easier in dry weather because the trails are not muddy. A Cu Chi Tunnels trip combined with a speedboat ride turns the logistics into one outing.

The Mekong Delta

The Mekong Delta is also at its best in the dry season. Canals are navigable, the roads are dry and the heat is bearable at dawn, which is when the Cai Rang floating market at Can Tho does its trading. For a gentle evening on the water, the Mekong fireflies kayak and boat adventure is the sort of low-key activity that is easiest when it is not raining. Mui Ne and its dunes are not part of the delta, but they enjoy the same dry weather and make a good coastal stop on the way north-east.

Phu Quoc and Con Dao

Phu Quoc, in the Gulf of Thailand, is at the beginning of its best season, which runs roughly from November to April. The sea is calm, the water is clear and the west-coast beaches are suitable for swimming, in contrast with the rough conditions of the wet season. A day of four-island snorkelling with a beach barbecue is the classic way to use it. See Phu Quoc for where to base yourself. Because December brings Christmas and New Year, flights and beach hotels fill up, so reserve early.

Who should aim south, and who can accept the north

Choose the south, and stay mostly there, if:

• you want beaches, swimming and sunshine in your photographs
• you are travelling with young children, older parents or anyone who dislikes the cold
• you only have a week and want the highest chance of good weather
• you are escaping a northern-hemisphere winter and expect warmth

A week built around Ho Chi Minh City, the delta and Phu Quoc is the safest December plan. Our southern Vietnam in one week itinerary does exactly that.

Accept the north in winter, and enjoy it, if:

• your interest is culture, food, history and cities rather than views
• you are happy with layers and a damp, grey day
• you want quiet bays and fewer crowds than in autumn
• you are combining Hanoi with a southern beach later in the trip

A good compromise for a two-week trip is to spend the first days in Hanoi and Ninh Binh and then fly south, so that the warm weather arrives when you need it. Domestic flights are short: Hanoi to Ho Chi Minh City takes about two hours, and the full route is explained in our domestic flights in Vietnam guide. The Reunification Express takes more than thirty hours end to end, so it suits only a part of the journey. If you are still weighing up a split, read north or south Vietnam.

December is not a month to claim that the whole country is in good shape. If someone tells you that Vietnam is “perfect in December”, ask them which part they visited.

What to pack

The challenge is the range. A single trip may take you from 12 °C in Hanoi or the mountains to 33 °C in Saigon, so pack for both. A light down or fleece layer, a rain jacket and long trousers cover the north. Light cotton, a hat and sunscreen cover the south. Closed shoes for wet cities, sandals for the coast. Our Vietnam packing list has a longer checklist.

Remember that tap water is not drinkable anywhere in Vietnam, that cash still matters at markets and street stalls, and that rules on entry depend on your nationality, so check the official immigration portal or your government’s advice before you travel.

Dates, crowds and Tet

December is not Tet. The lunar new year falls between late January and mid-February, on a different date each year, and the weeks before it bring crowded transport and closed businesses. Our Tet in Vietnam guide covers that period. For December itself the busy dates are the Christmas and New Year weeks, when southern beaches, flights and rooms are tight. If you can, travel in the first half of the month for better availability, or look at Vietnam in January if you are flexible.

Practical tips for December

• Book Christmas and New Year early. Flights to Phu Quoc and the best beach rooms go first.
• Leave slack in the north. Fog can delay a cruise or a mountain transfer, so avoid an international flight the same evening.
• Check the centre’s forecast. Rainy days can disrupt boats to the Cham Islands or Nha Trang’s islands.
• Dress in layers in Hanoi. It is warmer at midday and colder after dark.
• Prices: quote them with the year. Exchange rates drift, and roughly 26,000 VND to 1 USD and 28,000 VND to 1 EUR is the 2026 ballpark.

Frequently asked questions about Vietnam in December

Is December a good time to visit Vietnam?

It is a very good month for the south and a mixed one for the rest. Ho Chi Minh City, the Mekong Delta and Phu Quoc are dry and sunny, while the north is cool and grey and the centre is finishing its rainy season. Choose your region first, then your dates.

How cold is Hanoi in December?

Typically 13 to 20 °C, grey and often damp, with an occasional colder spell. It feels colder than the figure suggests because buildings are rarely heated. Pack a warm layer and a light waterproof.

Can I see snow or frost in Sapa in December?

Nights in the mountains can fall close to freezing and frost is possible, but you should not count on snow. Fog and cloud are more common than clear views, so keep expectations flexible and bring proper warm clothing.

Is Ha Long Bay worth visiting in December?

Yes if you accept grey light and mist, because the bay is calmer and quieter than in summer and there is no typhoon season. Expect cool air on deck and do not count on postcard blue skies. Lan Ha Bay is a quieter alternative.

Is it still raining in central Vietnam in December?

The rainy season on the central coast runs roughly until December, so showers, grey days and a swollen sea are still common in Hue, Da Nang and Hoi An. Nha Trang’s rains also finish around then. Da Lat stays cool and fresher because of its altitude.

Where is the best weather in Vietnam in December?

The south. Ho Chi Minh City, the Mekong Delta and Phu Quoc are in their dry season, with 25 to 35 °C and much less rain than in the wet months. Phu Quoc’s best season runs roughly from November to April.

Is December busy and expensive in Vietnam?

Late December is a peak period for the southern beaches and for Christmas and New Year travel, so book flights and Phu Quoc rooms early. Tet comes later in winter, and its date changes each year, so check the Tet page before planning.
