Southeast Asia
Southeast Asia Is Not One Trip, and the Monsoon Is Why
The region gets planned as though it were a country with a season. It is eleven countries sitting across the equator on at least three separate weather systems, which means there is no single best time to visit Southeast Asia, and anybody who gives you one has picked a favorite country and stopped thinking. Somewhere here is always dry. The skill is knowing where, in your month, then combining two or three places that reinforce each other. This page is about that decision. The individual guides carry the detail, best read once the shape is settled.
Know before you go
- The two hubs almost every itinerary starts or ends at Bangkok or Singapore. Both are worth three nights rather than a connection, and the wrong hub adds a day of backtracking.
- Trip length two countries need twelve to fourteen nights on the ground. Three need sixteen to eighteen. Anything shorter and you are buying internal flights rather than days.
- No regional season the mainland loop of Vietnam, Cambodia and Laos runs best from November to March. Bali is driest from roughly April to October, almost the opposite. Thailand's two coasts run on different rainfall calendars, which is why Phuket and Koh Samui are a choice rather than a pair.
- Vietnam is three climates the north around Hanoi is best from October to April, the center around Hoi An takes its rain from October into December, and the south around Ho Chi Minh City stays dry from November to April. Even inside one country the order matters.
- Entry is country by country there is no regional visa. Thailand admits United States passport holders without one but requires a digital arrival card filed shortly before you fly. Laos requires a visa, online or on arrival. Vietnam runs an electronic visa. Singapore wants an arrival card before you land.
- Laos sets the passport standard it is the strictest in the region on documents, wanting well over six months of validity and two genuinely blank visa pages. On a multi country trip that becomes the standard for the whole itinerary, so check passports at the planning stage rather than at the gate.
- Getting around short regional flights, not overland. Land borders cost entire days, and the low fare airlines connect almost everything. The exception is the Mekong, where the boat is the point.
- Money a different currency in every country, none worth carrying home. Cards work in cities, hotels and better restaurants. Cash rules markets, street food, temple donations, tuk tuks and tips, which is where the good part of the trip happens.
- Two dates to plan around Tet, the Vietnamese lunar new year in late January or February, closes shops and fills domestic flights for about a week. Songkran, Thai new year on 13 to 15 April, shuts much of Thailand down. Book either deliberately or route around them.
- Temple dress is a rule shoulders and knees covered, men and women alike, shoes off at the door, enforced by staff who turn people away. Pack for it rather than buying a cover up at the gate.
- The beach comes last finish on sand rather than starting there, and pick the coast by month rather than by name. Ending two temple heavy weeks on a beach works. Starting on one and then facing Angkor at dawn does not.
Which countries pair, and which quietly fight each other
The strongest pairings share a season and contrast in character. Thailand with Cambodia is the classic first trip: Bangkok for the city and the food, Chiang Mai for a different kingdom's architecture, Siem Reap for Angkor, then a Thai island. Vietnam with Cambodia works because Angkor sits naturally between the south of Vietnam and Bangkok. Laos belongs with either, and Luang Prabang is the quietest place in the region, which makes it the right third stop rather than the first. Malaysia and Singapore pair with each other and almost nothing else: Singapore, Kuala Lumpur and Langkawi make a neat ten day route entirely separate from the Indochina loop. What fights is Bali with the mainland. It sits on a different monsoon and a long flight away, and dropping it into a Vietnam itinerary costs two travel days.
The monsoon does the scheduling
Start with your month and let it choose the region. November to March is the reliable mainland window, when Vietnam, Cambodia, Laos and Thailand are all dry at once, and the only period when a three country loop needs no compromise. It is also the busy, expensive season, and December into January is held a long way ahead. April is the hottest month on the mainland and carries Songkran. May to October is the green season, which is underrated: rain arrives as heavy afternoon bursts rather than settled gray, Angkor is at its quietest and rates fall considerably. The exception is central Vietnam, which takes its heaviest rain from October into December. If your fixed month is European summer, the honest answer may be Bali or the Gulf coast rather than the mainland loop.
How long a first trip actually needs
Fourteen nights on the ground is the floor, and sixteen to eighteen is where it stops feeling like a schedule. A workable shape: three nights in Bangkok at the front, while jet lag has you awake at five and the temples are empty, three in Chiang Mai or straight on to Siem Reap for Angkor, three in Luang Prabang, then Vietnam north to south through Hanoi, Hoi An and Ho Chi Minh City, and four or five nights on a beach to finish. Note what it leaves out. Long haul arrival and departure days are not sightseeing days, and counting them as such is where most self built itineraries lose their margin.
The mistake is one country too many
It is always the same failure. Two weeks are planned, four countries go in because they look close on the map, and each gets three nights of which one is spent at an airport. The region punishes this because the flights are short but the airport time is not, and because the good part of every one of these places happens early in the morning after a night's sleep. Every country you add costs roughly a day and a half in movement before you have seen anything. The trip people remember is two done properly, or three with one given a long weekend by design rather than by accident.
Planning brief
A regional trip is built in one order: month, then countries, then sequence, then hotels. Reversing it is how itineraries fall apart.
- Best suited to: first trips to Asia; food and culture travelers; multi generation families using one hub; honeymooners wanting cities then a beach; repeat visitors going deeper.
- Decisions to settle early: the anchor month and therefore the region; two countries or three; which hub; where the beach goes and on which coast; whether Tet or Songkran falls inside the dates.
- Arrival and routing: a long haul into Bangkok or Singapore; regional flights rather than land borders; separate entry paperwork per country; passports checked against the Laos standard if Laos is in the route.
The month picks the countries, not the other way round
Give us the weeks you can travel, how long you have on the ground and what you want more of, temples, food, water or silence. Back comes a shortlist of countries that suit the month, the order they belong in, and an honest view on which to leave out.
Once the shape is agreed the country guides carry the detail, starting with Bangkok and Hanoi, and our luxury leisure travel planning coordinates the countries, flights, guides and pace as one journey.
Are private guides worth it here, or can we do it independently?
Take a guide for the historical days and travel independently the rest of the time. Angkor, the imperial city at Hue, the old quarters of Hanoi and Luang Prabang and the temple complexes in Bangkok all carry layers of religion, dynasty and reconstruction that are invisible without someone to read them, and the good guides also manage your timing against the coaches, which is worth as much as the interpretation. Markets, beaches and eating need nobody at all. Roughly one guided morning in every three days is the right rhythm, booked long before the hotels, because the strongest guides in each city are a short list.
Is Bali worth adding to a mainland itinerary?
Not to a first regional trip, and yes to a trip built around it. Bali sits on the opposite monsoon to Vietnam, Cambodia and Laos, so in the months when the mainland is at its best the island is in its wet half, and the flights across are long enough to cost two travel days each way. Dropped into two weeks it takes a week's worth of time and gives back three nights. Where it works is as the second half of an Indonesian trip, or paired with Singapore and a short Malaysian leg, which share its season and sit within a couple of hours of it.
Which two countries make the best first trip?
Thailand and Cambodia. Thailand gives you a great capital, a distinct northern kingdom in Chiang Mai and a beach on whichever coast suits your month, all with excellent infrastructure and the best hotel value in Asia. Cambodia gives you Angkor, which is the single most extraordinary thing in the region and needs two or three days rather than one. They share a season, the flights between them are short, and the contrast between them is real. Vietnam is the other strong first choice, but it is a country that wants ten days to itself rather than five, so it pairs better with a short Cambodian leg than with a full Thai one.
Is the green season a false economy?
No, and on the mainland it is one of the better trades in travel. From May to October the rain generally arrives as heavy afternoon bursts that clear within the hour rather than as all day gray, and the mornings, which is when temples and markets are best anyway, are frequently clear. Angkor is at its quietest, the landscape is at its greenest, rates fall considerably and restaurants and small hotels become bookable. The real caveat is central Vietnam, which takes its heaviest rain from October into December, so build a green season Vietnam trip early in the window and run it north to south.
When is the best time to visit Southeast Asia?
There is no single best time, because the region sits on at least three weather systems. The mainland loop of Vietnam, Cambodia and Laos runs best from November to March. Bali is driest from roughly April to October, almost the opposite. Somewhere is always dry, so pick places that suit your month. Start in Bangkok or Singapore.
