The short answer
Best overall: November to April. The south and centre are dry; the north is cool and pleasant. Best for south (Ho Chi Minh City, Phu Quoc): November–April — dry season, warm, brilliant for beaches. Best for central (Hoi An, Da Nang, Hue): February–May — dry, warm, and the quietest stretch before the summer crowds. Best for north (Hanoi, Ha Long Bay, Sapa): October–December and March–April — crisp and clear. Avoid: September–November for central Vietnam (typhoon risk). Budget travellers: May–June in the south — just before peak, heat manageable, prices lower.
Why Vietnam's weather is complicated
Vietnam is a long, narrow country — stretching over 1,600 kilometres from the northern border with China to the southern tip near Cambodia. This shape, combined with a central mountain range (the Truong Son), creates three distinct climate zones that are often in completely different weather patterns at the same time. When Hanoi is shivering through January fog, Ho Chi Minh City is 30°C and sunny. When typhoons are lashing Hoi An in October, Sapa is glowing in autumn colour and the south is entering dry season.
The practical implication: there is no single "best time to visit Vietnam" for the whole country. Instead, there's a best time for each region — and for multi-week itineraries, the art is sequencing your trip to follow dry weather from one region to the next. The classic route: start in the south (November–December), move to the centre (January–March), then head north (March–April). This strategy keeps you largely in dry conditions throughout.
The three climate regions
| Region | Key destinations | Best months | Avoid |
|---|---|---|---|
| South | Ho Chi Minh City, Mekong Delta, Phu Quoc, Con Dao | November – April | May–October (monsoon) |
| Central | Hoi An, Da Nang, Hue, Nha Trang | February – May | September–November (typhoons) |
| North | Hanoi, Ha Long Bay, Sapa, Ninh Binh | October–December, March–April | June–August (hot/humid), Jan–Feb (cold fog) |
Month-by-month guide
Peak season in the south; cool and clear in the north
January is peak season for the south — Phu Quoc and Con Dao beaches are at their best, Ho Chi Minh City is warm and dry, and the Mekong Delta is accessible and lush. The north is cold by Vietnamese standards (12–18°C in Hanoi, colder in Sapa where snow occasionally falls on the mountain passes). Ha Long Bay is cool and misty — atmospheric, but bring layers. Central Vietnam is starting to dry out after the November–December rains; Hoi An is pleasant by late January.
Tet season — extraordinary or challenging depending on your plans
Tet (Lunar New Year) typically falls in late January or February. It is simultaneously the best and worst time to visit. The atmosphere is extraordinary — flower markets, dragon dances, fireworks over Hoan Kiem Lake in Hanoi, the Hoi An Lantern Festival at its most spectacular. But practically: trains and flights sell out weeks ahead, prices spike 50–100%, and many street food stalls and family restaurants close for 5–10 days. Travellers who plan meticulously and arrive a few days before Tet for the build-up often have transcendent experiences. Those who arrive mid-festival without bookings find a partially closed country.
The sweet spot begins — central Vietnam shines
March is one of the best months in the Vietnamese calendar for a multi-region trip. Hoi An is warm, dry, and not yet swamped by summer tourists — the old town glows in the lantern light and the beaches at An Bang are perfect. Hanoi is mild and pleasant; the cherry and plum blossoms in the northern hill stations (Ba Vi, Moc Chau) are in bloom. Sapa is still cold at altitude but crystal-clear days in the rice terraces. Ha Long Bay is excellent — calm seas, good visibility, and fewer boats than summer. The south is still in dry season.
Last chance before the heat — arguably the best month overall
Many seasoned Vietnam travellers consider April the finest month. The north is warm without being hot; Hanoi's tree-lined streets are at their most pleasant. Ha Long Bay and Ninh Binh are in peak condition. Central Vietnam (Hoi An, Hue, Da Nang) is warm, dry, and still manageable before the Easter and summer crowds descend. Phu Quoc in the south is approaching the end of dry season — the sea is at its clearest. Giong Festival and Hung King Festival (national holiday around April 21) create traffic and domestic travel demand — book transport ahead.
Heat rising; good value before the summer rush
May marks the transition. The south is entering monsoon season and Phu Quoc's sea turns choppy. Central Vietnam (Hoi An, Da Nang) is hot and dry — beach weather, but the midday heat (32–35°C) demands shade between noon and 3 PM. The north begins its hot-humid season with the first thunderstorms arriving. Budget travellers and heat-tolerant visitors do well in May: prices are lower than the April peak and crowds are thinner. Sapa's rice terraces are a vivid green from the first rains.
High season crowds and heat; north is wet, south is very wet
Summer is high season for beach destinations in central Vietnam — Da Nang and Hoi An are packed with domestic tourists and the beaches are at their most lively. The rest of the country is less appealing: Hanoi and Ho Chi Minh City are brutally hot and humid, with daily downpours (usually in the afternoon). The Mekong Delta floods beautifully in a photogenic way. Ha Long Bay is in its wet season but boats still run; sea mist creates a dramatic atmosphere. Sapa's rice terraces are intensely green and photogenic — the best time for landscape photography despite the heat and rain.
Typhoon risk in centre; north is stunning
September is the most dangerous month for central Vietnam: typhoon season peaks, and Hoi An and Da Nang have experienced devastating floods from late-season storms (most recently significant flooding in 2020 and 2022). Travel insurance covering cancellations is essential if visiting the coast in September–October. However, October is extraordinary in the north — Hanoi is golden with autumn light, Sapa's rice terraces are being harvested (the most photographic time of year), and Ha Long Bay has calm, clear conditions. The contrast is stark: avoid central Vietnam in this period but prioritise the north.
Dry season returns to south; pleasant across the country
November is one of the most balanced months to visit Vietnam. The south's dry season begins — Ho Chi Minh City, the Mekong Delta, and Phu Quoc all shift to clear, sunny conditions. The north cools into its most comfortable temperature range (15–22°C in Hanoi). Ha Long Bay enters what many boat captains consider its finest season: clear skies, flat seas, and cooler temperatures that make the caves and kayaking genuinely pleasant. Hoi An has the famous Full Moon Lantern Festival in November. December sees prices rising toward Christmas and New Year — book accommodation 4–6 weeks ahead for the period December 22–January 2.
Best time by what you want to do

The ideal Vietnam itinerary: how to chase dry weather
The most practical approach for a 2–4 week Vietnam trip is to sequence your regions by the weather calendar. The classic "dry weather route" runs north to south in spring (March–April) or south to north in autumn/winter (November–January).
South-to-north in November–January
Fly into Ho Chi Minh City in November — the dry season is just beginning, and the city's energy, street food scene, and nearby Mekong Delta are at their best. Spend 4–5 days, then take a night train or short flight north to Hoi An (central Vietnam, now transitioning out of its wet season — expect some showers but improving daily). Spend 4–5 days here, then continue to Hanoi for the old quarter, street food, and as a base for Ha Long Bay (2 nights on a boat) and a day trip to Ninh Binh. Finish in the north in late December or January.
North-to-south in March–April
Start in Hanoi — warm spring weather, spring festivals, and the most beautiful Ha Long Bay conditions of the year. Head to Sapa for a weekend (rice terraces just planted, vivid green). Return south to Hue and Hoi An — dry season, uncrowded beaches. End in Ho Chi Minh City in April before the south's dry season ends in May. This direction tends to have slightly better weather throughout.

Plan my Vietnam trip →Frequently asked questions
When is the best time to visit Vietnam overall?
November to April is the safest window for a multi-region Vietnam trip. The south and centre are dry and sunny; the north is cool and mostly dry. For the north specifically, March–April and October–November offer the most comfortable conditions. Avoid September–November if prioritising central Vietnam (Hoi An, Da Nang) — typhoon season peaks then.
What is the weather like in Vietnam in December?
December is one of the best months to visit Vietnam. The south (Ho Chi Minh City, Mekong Delta) is dry and warm at 27–30°C. Central Vietnam (Hoi An) is cooler at 20–24°C with occasional showers. The north (Hanoi, Ha Long Bay) is cool and dry at 15–20°C — bring a light jacket. Crowds are moderate; prices are mid-range before the Christmas–New Year peak.
Can you visit Vietnam during monsoon season?
Yes, but with caveats. When the south is in its wet season (May–October), the north is dry — and vice versa. A well-planned itinerary can chase dry weather year-round. Heavy downpours in the wet season are usually short but intense (1–2 hours in the afternoon), and many travellers find the lush green landscapes and lower prices worth the trade-off. Avoid the coast and Hoi An during typhoon season (September–November).
When is Tet (Lunar New Year) in Vietnam?
Tet falls in late January or February (the exact date shifts each year with the lunar calendar). It is the most important festival in Vietnam — extraordinary to witness but practically challenging for travellers. Domestic flights and trains book out weeks ahead, hotels double in price, and most family-run restaurants, street food stalls, and shops close for 5–10 days. Book everything well in advance or avoid the 10-day window around Tet entirely if flexibility matters.
Is Vietnam good in February?
February can be excellent or tricky depending on Tet timing (see above). Outside of Tet, weather is good across most regions: the south is in dry season, central Vietnam is warming up and mostly dry, and the north (while still cool) is pleasant for sightseeing. February is also when the Hoi An Lantern Festival is most atmospheric. If Tet doesn't fall in February, it's actually one of the quieter and more pleasant months to visit.
