Destinations to explore
Vietnam stretches 1,600 km from north to south — the weather in the north and south is often reversed. The right month depends on your itinerary as much as your preferences.

Vietnam is the only country in Southeast Asia where the answer to "when to go" is really complicated. The country is 1,650 km from north to south and crosses several climate zones. When the weather is nice in Hanoi, it often rains in Ho Chi Minh City — and vice versa.
The rule of thumb: there is always a part of Vietnam at its best. The question is which part you want to see, and when.
The North (Hanoi, Sapa, Halong Bay) has a real cold season. December-February: 15 to 20°C during the day, cool at night. July-August: hot and humid, typhoons possible. The best period: March-April (30°C, dry) and October-November (pleasant, autumn light).
The Centre (Hội An, Huế, Da Nang) follows a reverse schedule. The rains fall from October to January — the floods in Hoi An are real in November. The best time: February-August, with a peak quality in March-May (before the heavy heat of summer).
The South (Ho Chi Minh City, Mekong, Phu Quoc) has two distinct seasons: dry (November-April) and wet (May-October). The southern monsoon does not make the journey impossible — the showers are short and violent, the sun returns quickly. But the roads of the Mekong can be flooded. Best time: November-March.
January-February: excellent in the South and in Hoi An. The North is cold but clear. Tet (Lunar New Year, late January or early February) closes many shops and transport for 3 to 5 days — plan or avoid depending on preference.
March-April: the best window for a complete North-Centre-South tour. The North is warming up, the Centre is ideal, the South remains dry. Book early: April is the high season.
May-June: the south enters the monsoon. The north and centre remain good. Sapa in May: the rice fields are starting to green up, the terraces of rice in water are photogenic.
July-August: typhoons threaten the North. The Centre is hot and humid. The South is in the middle of the monsoon. Avoid for a complete tour, but possible for Ho Chi Minh City and the southern beaches if you accept the showers.
September-October: the north is back in good conditions. Sapa in September-October: the rice terraces of Mù Cang Chải are intense gold — the most famous photos of the region date from this period. The center is to be watched (typhoons in October-November).
November-December: excellent in the South, risky in the Centre (floods in Hoi An). Hanoi in November: bright, mild, few people.

Halong Bay: March-May and September-November. The January mists create a special atmosphere. Avoid July-August (typhoons and overcrowding).
Sapa and the rice terraces: September-October (golden rice at harvest) and May-June (rice in water, bright green). December-January: permanent fog and temperatures close to 0°C at night.
Hội An: February-August. Avoid October-November absolutely (possible flooding in the old city).
Ho Chi Minh City: November-April. The city is liveable all year round, but the monsoon in May-October adds heavy humidity.
Phu Quoc: November-April. The best water for snorkeling and beaches. May-October: rough seas, some water activities closed.
10 days: Choose a zone. North (Hanoi + Halong + Sapa): March-April or October. South (HCMC + Mekong + Phu Quoc): November-March. Central (Hoi An + Huế + Da Nang): March-June.
15-21 days: North-Centre-South circuit possible. The ideal window is March-April, the only period when all three zones are simultaneously in good conditions.
