Best time to visit Southeast Asia: A country-by-country guide
Mainland Southeast Asia peaks November–February; Indonesia and Malaysia’s east coast run opposite, May–September. Plan your visit here.
The best time to visit mainland Southeast Asia is the dry season, November to February. Temperatures are cooler and humidity is low across Thailand, Vietnam, Cambodia, Laos, and Myanmar.
But the region does not follow one weather pattern. Indonesia and Malaysia’s east coast run on the opposite schedule, with their best months falling between May and September.
That means it is always dry season somewhere in Southeast Asia. To stay connected throughout your trip, consider an eSIM for Southeast Asia from Holafly for unlimited data and seamless coverage. This guide breaks down when to visit each part of the region, month by month.

Best time to visit mainland Southeast Asia
Mainland Southeast Asia covers Thailand, Vietnam, Cambodia, Laos, and Myanmar. All five share broadly the same seasonal pattern.
Best months: November to February.
This is the dry season. You get clear blue skies, comfortable temperatures, and the easiest conditions for temple visits and outdoor exploring.
The drawback: this is peak tourist season. Expect larger crowds and higher prices, especially around the December holidays. Before you pack your bags for the Southeast Asia trip, here is what to expect.
Country-specific timing on the mainland
- Thailand: dry season November to April. The rainy season runs May to October.
- Vietnam: a southwest monsoon May to September and a northeast monsoon October to April. It is almost always dry season at one end of the country.
- Cambodia: dry season November to April, monsoon May to October.
- Laos: dry season November to April, wet season May to October.
- Myanmar: dry season November to May, monsoon June to October.
For a full breakdown of Thai seasons, see our guide to the best time to visit Thailand. For Vietnam specifically, our guide to the best time to visit Vietnam covers each region in detail.
Tip: Vietnam is long enough to span two climates at once. If the north is wet, the south is usually dry. Check the specific region you are visiting rather than the country as a whole.
Best time to visit Indonesia and the islands
Indonesia runs opposite to the mainland. Bali and Lombok are best from May to September.
This is Indonesia’s dry season. You get sunny days and low humidity while much of the rest of the region is under monsoon rain.
The drawback: July and August bring peak international crowds and higher accommodation costs.
Indonesia’s wet season runs November to March. Rain tends to come in short heavy bursts rather than all-day downpours, so travel is still viable.
To ensure you stay connected throughout your trip, an eSIM for Indonesia is a must have. For a deeper look at the best time to visit Bali, look for festival calendars.
Tip: May and September are the sweet spot for Bali. You get dry season weather without the July and August crowds or peak pricing.
Best time to visit Malaysia: east coast vs west coast
Malaysia is the one country where the coast you pick matters more than the month.
The two coasts run on opposite monsoon schedules. That means there is good beach weather somewhere in Malaysia during almost any month of the year.
West coast: November to March
This covers Langkawi and Penang. The west coast faces the Strait of Malacca and stays sheltered during the northeast monsoon.
East coast: May to September
This covers the Perhentian Islands and Tioman. The east coast faces the South China Sea and is best in the middle of the year.
Many east coast island resorts close entirely between November and February, when the northeast monsoon hits hardest. Check before booking.
Tip: If your dates are fixed, pick your Malaysian coast to match. Travelling in January? Head to Langkawi. Travelling in July? The Perhentians will be at their best.
Southeast Asia weather by month
Here is where to go in Southeast Asia for each month of the year, based on where the dry season falls.
| Month | Where to go | Why |
|---|---|---|
| January | Vietnam | Dry across the country. Tet festival falls late January or early February. |
| February | Malaysia (west coast) | Peak dry season in Langkawi and Penang. |
| March | Thailand, Cambodia | Last of the dry season before the April heat. |
| April | Indonesia | Dry season begins in Bali. Songkran runs April 13-15 in Thailand. |
| May | Indonesia, Malaysia (east) | Both enter dry season. Good value before peak crowds. |
| June | Bali, Perhentian Islands | Reliable dry weather, before July and August crowds. |
| July | Indonesia, east coast Malaysia | Peak dry season, but also peak international crowds. |
| August | Bali, Lombok | Still dry. Hungry Ghost Festival falls August or September. |
| September | Indonesia, Malaysia (east) | Dry season ending. Fewer crowds, lower prices. |
| October | Myanmar | Monsoon ending. Thadingyut Festival of Lights. |
| November | Laos, Thailand, Vietnam | Mainland dry season begins. Excellent conditions. |
| December | Cambodia, Thailand | Peak mainland dry season. Book early for the holidays. |
Tip: If your dates are already fixed, work backwards from this table. There is a good destination in Southeast Asia for every month of the year.
Worst time to visit Southeast Asia
There is no single bad month for the whole region. But there are periods worth planning around for specific countries.
March to April: mainland heat
The weeks before the rains arrive are the hottest of the year across the mainland. Temperatures and humidity both spike, which makes long days of sightseeing hard work.
May to October: monsoon season
This is the rainy season across most of the mainland. Showers are often short and heavy rather than constant.
It is not a reason to cancel. Landscapes turn bright green, crowds drop significantly, and prices fall. For budget travellers, this is often the best value window of the year.
Typhoon season in the Philippines and Vietnam
The Philippines has a typhoon season running June to November, with the peak from July to October. Northern and eastern Luzon, Bicol, and Eastern Visayas are the most exposed regions.
Vietnam’s typhoon season runs June to November, peaking August to October. Storms tend to hit the north earlier in the season, shifting toward the central coast around Hue, Da Nang, and Hoi An later on.
Southern Vietnam and the Mekong Delta stay less exposed. In the Philippines, Palawan and the western Visayas tend to stay drier and more sheltered.
December holidays: crowds and pricing
Late December is the busiest and most expensive period across the mainland. If you are travelling then, book accommodation and internal flights well in advance.
Tip: Travelling during typhoon season is still workable with planning. Build in buffer days, choose flexible fares, and pick sheltered regions rather than exposed coastlines.
Best time to visit Southeast Asia for festivals
Southeast Asia has some of the most distinctive festivals in the world. Several are worth planning a trip around.
Tet Nguyen Dan — Vietnam, late January or early February
Vietnam’s lunar new year. Expect dragon and lion dances, fireworks, decorations, traditional rice cakes, and visits to religious sites.
Nyepi — Bali, March
A day of complete silence. For 24 hours all businesses shut, lights go off, traffic stops, and access to internet, radio, and TV is halted across the island.
The Melasti and Bhuta Yajna rituals lead up to it. There is nothing else like it anywhere in the world.
Songkran — Thailand, April 13-15
The Thai New Year, best known for nationwide water fights. Water guns, buckets, and even elephants with water cannons get involved. It symbolises washing away the past year’s misfortunes. If you’re planning to join the festivities, make sure to stay connected with an eSIM for Thailand.
Pahiyas — Philippines, May
A harvest festival in Lucban. Locals decorate their houses with fruit, vegetables, and rice, accompanied by traditional Filipino music and dance.
Hungry Ghost Festival — regional, August or September
Celebrated across Southeast Asia. Offerings are made to spirits, and lotus lanterns are lit on rivers through the night to guide them home.
Thadingyut — Myanmar, October
The Festival of Lights. Three days marking the end of Buddhist Lent, with homes, streets, and pagodas lit by traditional lanterns and oil lamps.
Which country to visit in Southeast Asia
If your dates are flexible, pick the country first. If your dates are fixed, pick the country that suits the season.
- First-time visitors: Thailand. The easiest country to travel in, with the best tourist infrastructure in the region.
- Beaches: Indonesia or Malaysia, depending on the month. The Philippines for island hopping outside typhoon season.
- History and temples: Cambodia for Angkor, Myanmar for Bagan.
- Quieter travel: Laos. Less developed for tourism, and all the better for it.
- Food: Vietnam and Thailand are the two standouts.
Is Thailand or Vietnam cheaper?
Vietnam is generally cheaper than Thailand for accommodation, food, and transport. Both are affordable by regional standards.
Laos and Cambodia sit at the cheaper end of the region. Singapore and Brunei are significantly more expensive than everywhere else in Southeast Asia.
What is the prettiest country in Southeast Asia?
It depends what you are looking for. Vietnam has the most dramatic landscapes, from Ha Long Bay to the northern mountains.
The Philippines has the best beaches and island scenery. Laos offers the most unspoiled river and mountain country in the region.
