Best Time to Visit Vietnam, Region by Region

Vietnam runs 1,650 km from the Chinese border to the Mekong Delta, so there is no single “best time to visit”. The country holds three separate climates at once, and the month that is perfect for Ha Long Bay can be the wettest week of the year in Hoi An. Here is what the weather actually does, region by region, and how we build itineraries around it.

Northern Vietnam — Hanoi, Ha Long Bay, Sapa, Ninh Binh

The north has four real seasons. October to April is the classic window: dry, clear air over the karsts of Ha Long and Bai Tu Long, and comfortable trekking weather in Sapa. December and January can drop to 10–14°C in Hanoi and near freezing on the Sapa ridges, so pack a proper jacket rather than a fleece.

March to April is our own favourite month range for photography: rice terraces are being flooded and the light is soft. May to September is hot and humid with afternoon downpours, and it is also typhoon season on the coast — cruises do occasionally get cancelled by the port authority in August and September, which is why we always keep a land-based alternative in the file.

Central Vietnam — Hue, Hoi An, Da Nang, Phong Nha

The centre is the region most travellers get wrong. Its rainy season arrives late: September to November brings the heaviest rain of the year and Hoi An’s old town floods most seasons. The reward window is February to May, when the beaches are usable, the heat has not peaked and the Hai Van pass is clear.

June to August is dry but very hot — 35°C plus — so we schedule Hue’s citadel and My Son early in the morning and keep the afternoon for the beach or a cooking class.

Southern Vietnam — Ho Chi Minh City, Mekong Delta, Phu Quoc

The south only has two seasons. December to April is dry and reliably sunny — the peak season for Phu Quoc and Con Dao. May to November is the green season: it rains hard for one or two hours in the afternoon, then clears. Delta water levels are higher and more atmospheric in September and October, and hotel rates are noticeably lower.

Putting a two-week trip together

• November to April — the only period when all three regions are broadly good. Best for a first, full-country trip. Book cruises and boutique hotels three to four months ahead.
• May to August — favour the north and the south, keep central Vietnam short, and build in beach days for the heat.
• September to October — excellent value and beautiful in the north and the delta; we usually reroute clients away from the central coast.

Public holidays worth knowing

Tet (Lunar New Year, late January or February) is the one date that changes everything: domestic transport sells out, many family-run restaurants close for a week and prices rise. It is a fascinating time to be in Vietnam if you accept the closures. Reunification Day (30 April) and National Day (2 September) fill the beaches with domestic travellers.
