North, centre or south? Vietnam has three climates in one country. Here is when to go, month by month, and how to plan one trip from Europe that gets good weather everywhere.
Quick answer: For a classic north-to-south trip, the best time to visit Vietnam is late October to April. If you can only travel in the European summer (July–August), focus on central Vietnam (Hoi An, Da Nang, Hue), which is sunny and dry exactly when the north and south are at their wettest.
Ask ten people in Vietnam about the weather and you will get ten different answers — and they will all be right. The country stretches about 1,650 km from the Chinese border to the Gulf of Thailand, so on the same January morning Hanoi can be a cool 16°C under grey skies while Ho Chi Minh City is a sticky 32°C in full sunshine.
That sounds complicated, but it is actually good news for European travellers. There is no single "bad" month for Vietnam. There is only a smarter route for the month you can travel. Below we explain the three weather zones, then go through the year month by month, with practical advice on school holidays, Tet and typhoon season.
Vietnam's three climate zones in plain words
Northern Vietnam: Hanoi, Ha Long Bay, Ninh Binh, Sapa
The north has four seasons, which surprises many visitors. Winter (December–February) is cool and often overcast: think 14–20°C in Hanoi, colder at night in Sapa, where frost is possible. Spring (March–April) and autumn (September–November) are the sweet spots — mild, mostly dry and clear. Summer (May–August) is hot and humid, around 32–35°C, with heavy but short tropical downpours.
Central Vietnam: Hue, Hoi An, Da Nang, Quy Nhon
The centre follows its own rhythm. It is sunny and dry from February to August, which is why Hoi An and the Da Nang beaches are perfect for a European summer holiday. The rainy season runs from September to December, with October and November bringing the heaviest rain, occasional flooding in Hoi An's old town and the risk of tropical storms.
Southern Vietnam: Ho Chi Minh City, Mekong Delta, Phu Quoc
The south is tropical and warm all year (27–35°C). The dry season runs from December to April. From May to November it rains most days, but usually as a strong afternoon shower rather than all-day rain — you can still travel comfortably, and prices on Phu Quoc are lower.
Vietnam month by month
| Month | North (Hanoi, Ha Long) | Centre (Hoi An, Hue) | South (Saigon, Phu Quoc) | Our verdict |
|---|---|---|---|---|
| January | Cool, grey, 15–20°C | Showers easing, mild | Dry, sunny, ideal | Great for south + centre |
| February | Cool, drizzle, Tet holiday | Dry season starts | Dry, hot | Good — check Tet dates |
| March | Warming, misty mornings | Dry, pleasant | Dry, hot | Excellent everywhere |
| April | Warm, mostly dry | Dry, warm | Hottest month | Excellent everywhere |
| May | Hot, first storms | Hot, dry, beach weather | Rains begin | Good for the centre |
| June–August | Hot, humid, showers | Peak beach season | Afternoon rain | Best for central Vietnam |
| September | Warm, fewer storms | Rains begin | Rainy | Good for the north |
| October | Dry, clear, 25°C | Heavy rain, storm risk | Rain easing | North yes, centre no |
| November | Dry, golden light | Wettest month | Dry season begins | North + south |
| December | Cool, dry | Rainy | Dry, sunny | North + south, festive |
Visiting Vietnam in the European winter (November–March)
This is the most popular time for European travellers, and for good reason: escaping a dark December in Hamburg or Tallinn for 30°C on a beach in Phu Quoc is hard to beat. The ideal winter route starts in the north while it is dry, moves through the centre once the rains ease (from mid-January), and ends in the sunny south.
- Pack a light jacket and a scarf for Hanoi and Ha Long Bay in December–February — evenings on deck can be chilly.
- Sapa can drop close to freezing in January. If you love trekking, March–May or September–November are more comfortable.
- Christmas and New Year are peak season for cruises and beach resorts. Book three to four months ahead.
Tet: Vietnamese New Year
Tet is the most important holiday of the year and falls in late January or February (in 2027 it is in early February). For a few days many family-run restaurants and shops close, domestic flights and trains are full, and hotel prices rise. It is also a beautiful time to see flower markets and family celebrations. If you travel during Tet, book transport early and keep the itinerary relaxed around the main holiday days.
Visiting Vietnam in the European summer (June–August)
Families tied to school holidays often worry that summer is "rainy season". In reality it depends where you go. Central Vietnam — Hoi An, Da Nang, Hue and the beaches of Quy Nhon — is at its sunniest. We usually suggest a summer plan like this:
- 3–4 nights in Hanoi and Ha Long Bay (hot, with short showers — still very enjoyable).
- 5–7 nights in Hoi An and Da Nang for culture, cooking classes and the beach.
- Optional 2–3 nights in Ho Chi Minh City and the Mekong Delta, with flexible afternoons for rain.
Typhoon season: what European travellers should know
Tropical storms can affect the central and northern coast between roughly August and November. Most trips are not affected at all, but Ha Long Bay cruises are occasionally suspended by the authorities for a day when a storm approaches. A good local operator will move your cruise or swap in an alternative, such as Ninh Binh. This is one of the clearest advantages of booking with a DMC that has its own team in Vietnam: decisions are made on the spot, not from a call centre.
Our recommended routes by travel month
- October–April: the classic north-to-south journey — see our Classic Vietnam: North to South itinerary.
- November–March, one week only: Hanoi, Ha Long Bay and Da Nang, as in our Magical Vietnam Winter Escape.
- May–August: Hanoi plus a longer stay in Hoi An and Da Nang.
- December–April beach holiday: Hoi An culture followed by Phu Quoc sunshine — ideal for honeymoons.
Festivals worth planning your trip around
Weather is only half of the story. Vietnam's festival calendar follows the lunar year, so the dates move every year, but a few events are worth knowing about when you choose your travel month:
- Tet (late January or February): peach and kumquat trees everywhere, flower markets in Hanoi and Saigon, and a rare chance to see family traditions. Expect closures on the first three days.
- Hoi An full-moon nights (monthly): on the 14th day of each lunar month the old town turns off its electric lights and lanterns take over.
- Hung Kings' Festival (spring): a national holiday honouring the legendary founders of Vietnam, with temple ceremonies north of Hanoi.
- Mid-Autumn Festival (September or October): the children's festival, with lion dances, mooncakes and lantern processions — magical in Hanoi's Old Quarter and Hoi An.
- Rice harvest in the north (September–October): the terraces around Sapa and Mu Cang Chai turn golden — a photographer's favourite.
Matching Vietnam to European holiday periods
Most of our guests travel within fixed holiday windows rather than choosing the "perfect" month. Here is how we usually advise them:
| Holiday window | Typical dates | What we suggest |
|---|---|---|
| Autumn half-term / Toussaint / Herfstvakantie | Late October – early November | North (Hanoi, Ha Long, Ninh Binh) + south (Saigon, Mekong, Phu Quoc) |
| Christmas & New Year | Late December – early January | North-to-south with a beach finish; book early |
| Carnival / ski holidays / February half-term | February | Centre and south; check the Tet dates |
| Easter | March – April | Everywhere — ideal for a full north-to-south route |
| Pentecost / Ascension long weekends | May – June | Centre and beaches; good value |
| Summer holidays | July – August | Hoi An, Da Nang, Hue, plus a short Hanoi stay |
What to pack for each season
Because the climate changes as you travel, layering is the secret. For a winter trip, bring a fleece or light down jacket for Hanoi and the cruise, plus summer clothes for the south. In summer, choose breathable linen and cotton, a compact umbrella and quick-dry shoes. In every season, pack a long-sleeved top and something to cover your knees for temple visits, a good sunscreen and insect repellent. Laundry services in Vietnam are fast and inexpensive, so you can travel light.
A note on climate and changing weather patterns
Like many places, Vietnam has seen more irregular weather in recent years — earlier or later rainy seasons and occasional unseasonal storms. That is another reason we build some flexibility into every itinerary: a spare afternoon in Hoi An, an alternative plan for a cruise day, and local staff who monitor forecasts daily.
Frequently asked questions
What is the cheapest time to visit Vietnam?
May, June and September are usually the best value. Flights from Europe are cheaper outside school holidays and Christmas, and hotels in the south and on Phu Quoc offer low-season rates.
Is Vietnam too hot in summer?
It is hot (32–35°C) and humid in Hanoi and Saigon, but very manageable with early starts, a long lunch break and air-conditioned transport. The central coast has a sea breeze and is ideal for beach time.
When is the best time for a Ha Long Bay cruise?
October to December and March to May offer the best combination of clear skies, calm water and comfortable temperatures.
Can I visit Vietnam in October?
Yes — the north is at its best in October. Simply avoid spending many nights in Hoi An and Hue, where October is the start of the heaviest rains.
Is December a good month for Vietnam?
Yes, for the north and south. Hanoi is cool and dry, Ha Long Bay is clear and the south is sunny. Central Vietnam can still be rainy in early December.
Is it worth visiting Vietnam during Tet?
It is a unique cultural experience, but plan carefully: book transport early and expect some closures during the first days of the holiday.
