Cheapest Time to Visit Vietnam

September and October are the cheapest months to visit Vietnam, with flights and rooms 30 to 40% below December. May is the runner-up and has much better weather. What you give up in September and October is central Vietnam: it is the wettest period of the year there, and river tours and coastal beach days are the first things to go. Prices checked September 2026.

The saving is real and it is not evenly spread. Flights and beds drop hard. Guided tours, entrance fees and food barely move. So the cheapest trip is not the one taken in the cheapest month, it is the one where the expensive lines happen to be the ones that fall.

The cheapest months to visit Vietnam

Sources disagree on which wins, and the disagreement is the useful part. Airfare data puts October lowest, because it is the only month rated low season from all five major origin regions at once. Hotel data favours June to September, when coastal rooms bottom out. If you are flying long-haul the flight decides it, and October wins. If you are already in Asia, the rooms decide it.

Mid-November is the answer for most people, and it is the one this article would actually recommend. It is past the central-coast typhoon peak and before the Christmas spike, the weather works in all three regions, and you still pay 20 to 30% less than January. It is a smaller saving for a much better trip.

At Tet the whole country travels home at once, and domestic fares run two to three times off-peak.

How much you save in Vietnam low season

Across a two-week trip that is roughly 300 to 600 US dollars per person on beds and internal flights alone, before the long-haul ticket.

The budget Vietnam itinerary assumes low-season pricing throughout, and affordable Vietnam islands is where the green-season resort discounts bite hardest.

The cheapest fortnight of the year and the most expensive fortnight of the year are about six weeks apart. Everything turns on Tet. Land on the wrong side of it and a room that was twelve dollars is forty, with worse availability.

The weeks that cost double

Three periods break the pattern and you should plan around them rather than through them.

A bowl of pho costs 26,000 to 52,000 dong in every month of the year.

Tet. Lunar New Year falls on Saturday 6 February 2027, with the statutory holiday running 5 to 9 February and the practical national shutdown stretching from around 5 to 13 February. Hotels take 50 to 80% premiums, tours and cruises add 40 to 60%, and domestic air runs two to three times off-peak because the entire country is travelling home at once. Flights, trains and buses sell out months ahead. Tet 2027 covers what actually stays open, which is the question that matters more than the price.

Christmas and New Year. Late December is the annual maximum for hotel rates nationally, on top of the dry-season peak in the south.

Dong Hoi averages 650mm of rain in October against 40mm in February.

June to August, if you are flying from Europe or Australia. Hotels are cheap and the long-haul ticket is not, because it is the northern summer holiday. This is the trap in the "June to September is cheapest" advice: it is true on the ground and false in the air.

What never gets cheaper in Vietnam

This is the part budget guides leave out, and it changes how you plan.

• Guided tours. A guide, a porter and a safety team cost the same in October as in April. Expedition prices do not have a low season, because the cost is people, not beds.
• National park entrance fees. Set by the provincial tourism authority and fixed year-round. Phong Nha Cave is 150,000 dong whatever the month.
• Food. A bowl of pho is 26,000 to 52,000 dong in every month of the year.
• Visas. The e-visa is 25 USD in every month, and free year-round for the 23 visa-exempt nationalities.

There is one real exception. The Dark Cave package drops from 450,000 dong to roughly 250,000 to 270,000 once the mud bath and water activities close for the season, which is a genuine low-season discount and also a smaller day out. Dark Cave explains what is left when the water sections stop.

Small independent places are where the low-season price actually drops.

When to book flights and rooms for Vietnam

Six to seven weeks ahead saves 20 to 23% against booking last minute on long-haul routes to Vietnam. Booking much earlier rarely helps.

Cave tours run whatever the weather is doing above ground.

Tet is the exception in both directions. Book Tet flights when the sales open, which is September or October of the year before, because the cheapest buckets on the peak dates sell first and never return. For accommodation over Tet, November and December are the last useful moments.

Making the cheap months work

The honest problem with September and October is that they save you money by taking central Vietnam away. Dong Hoi averages 650mm of rain in October against 40mm in February, so beaches are out and boat trips are unreliable.

The exception is underground. Across September, October and November, Jungle Boss closes exactly three tours, Bach Ma Discovery and the two Do Quyen Waterfall trips, and reopens them on 1 December. Everything else runs all year, including every multi-day expedition, because a cave is the same temperature and the same dryness in October as in April. Budget Phong Nha tours start at the cheap end of that list.

So the low-season trip that works is north for landscape, centre for caves rather than coast, south for the dry end of its season. Where to stay in Phong Nha and Phong Nha restaurants both run at low-season rates from September, and Hanoi to Phong Nha on a budget is the cheapest way in.

For which month suits the weather rather than the wallet, the best time to visit Vietnam answers a different question and gives a different month.
