Best time to visit Vietnam: weather and seasons by month

Vietnam runs on three weather systems, not one. The north has four seasons, the centre has a monsoon that arrives when the south is dry, and the south is hot all year with a wet afternoon season from May to November. That is why the useful question is not "when is Vietnam good?" but "which region am I going to?"

Use the table as a filter, then read the region notes below it. If you only have one window and want the classic Hanoi–Hội An–Ho Chi Minh City route, February to April is the safest bet.

North — Hanoi, Hạ Long, Ninh Bình, Sa Pa. October and November are the pick: dry, clear and cool enough to walk all day. April is the second window. December to March is grey and damp rather than cold, but Sa Pa can drop to around 0 °C, so pack a real jacket. July to September is hot, humid and storm-prone, and Hạ Long overnight cruises are the first thing cancelled when a warning goes out.

Centre — Huế, Đà Nẵng, Hội An, Quy Nhơn. March to May is the beach window, with warm water and low rain. The monsoon runs September to February, the opposite of the south, and Hội An's old town floods in most Octobers and Novembers. If Hội An is the point of the trip, keep dates loose or move the visit to spring.

South — Ho Chi Minh City, the Mekong, Phú Quốc. December to April is dry and hot. May to November is the wet season, but it usually means a heavy one-to-two-hour afternoon downpour rather than a washed-out day; mornings stay usable. Phú Quốc is at its best in the same December-to-April window.

October and November are the cheapest months on the country page — low crowds, low prices — but that is also the central flood peak, so the saving only makes sense if you are staying north or south. February is the opposite: Tết (Lunar New Year, 6 February 2027) closes many restaurants and shops for three to seven days and sells out trains, buses and flights a week either side.

The other dates that move prices are the 30 April–1 May long weekend, when beach towns and Hạ Long fill completely, and Christmas to New Year, which lifts coastal hotel rates. National Day on 2 September is a two-day domestic travel peak, and Hùng Kings' Day in April adds a long weekend. Vietnam Culture Day, a new paid public holiday on 24 November from 2026, may close offices and some museums — check the 2027 arrangement.

For budgeting by month, see the cost page; the spread between low and high season is mostly accommodation and domestic flights, not food.

A north-to-south trip in February to April crosses three climates in one itinerary: a light jacket and long sleeves for Hanoi mornings, beach clothes for the centre, and hot-weather kit for the south. In the wet months, add a compact rain shell and dry-bag or zip pouches for electronics, and expect ferries and cruises to be the first services delayed.

For the north in December to March, layers matter more than a heavy coat in the cities, but Sa Pa and Ha Giang nights need a proper warm jacket. In the centre's monsoon, shoes that dry fast beat waterproof boots.

Fix the region first, then the month. If you want one trip covering the whole country, take February to April and accept that the centre's beaches are warm rather than perfect. If you can travel in October or November and are happy to stay north and south, you get the best weather and the lowest prices of the year.

If your dates are locked by work or school, do not force the classic route: in July, go north-coast islands and the centre; in October, go north and south and skip Hội An; in February, book Tết transport weeks ahead or shift by a week.
