Southeast Asia is one of the world’s great travel regions, but its weather is anything but uniform, and getting the timing wrong can mean weeks of rain. The best time to visit Southeast Asia in 2026 depends heavily on which countries you plan to see, because the dry and monsoon seasons shift across the region and even flip between coasts of the same country. This guide breaks down the ideal window country by country, so you travel in sunshine and skip the worst of the rain and crowds.
As a broad rule, the November to March dry season is the safest bet for most of the region, while the shoulder months offer fewer crowds and lower prices.

The quick answer: best overall window
For a first trip covering the mainland, November to February is the sweet spot: dry, cooler and comfortable across Thailand, Vietnam, Cambodia and Laos. March and April get very hot and hazy inland, and May to October brings the southwest monsoon to much of the region, though it rarely rains all day and travel is cheaper and quieter then.
Thailand
Thailand is at its best from November to March, when the whole country is dry, sunny and pleasantly warm. April is the hottest month, peaking with the Songkran water festival, and the rains arrive from May. Note the coasts differ: the Andaman side, including Phuket and Krabi, is driest November to April, while the Gulf islands like Koh Samui stay drier a little later into the year.

Vietnam
Vietnam is long and thin, so there is no single best time. For the north (Hanoi, Sapa, Ha Long Bay), aim for October to April. Central Vietnam (Hoi An, Da Nang) is driest February to May. The south (Ho Chi Minh City, the Mekong) is dry December to April. If you are traveling the whole country, spring around February to April gives you the best overall balance.
Bali and Indonesia
Bali and much of Indonesia enjoy their dry season from May to September, the opposite of the mainland, which makes it a perfect wet-season escape from countries like Thailand. April and October are excellent shoulder months with good weather and fewer crowds. Avoid January and February if you want reliable sun, as these are the wettest months. Find stays in Bali on Agoda.
Malaysia and Singapore
Malaysia and Singapore are hot and humid year-round with no true dry season, but the west coast (Kuala Lumpur, Penang, Langkawi) is driest from December to February and June to August. The east coast and Borneo are best March to October, as they catch heavy rain late in the year. These make handy hubs you can visit almost anytime.
Cambodia and Laos
Cambodia and Laos follow the mainland pattern: November to February is dry and cooler and ideal for temples like Angkor Wat. March to May is intensely hot, and the rains from June to October turn the landscape lush and green while keeping crowds low. Early in the dry season, around November, offers greenery without the rain.
Philippines
The Philippines is best from December to May, its dry season, with March and April ideal for island-hopping around Palawan and Cebu. The typhoon season runs roughly June to November and mainly affects the east, so travel is still possible with flexible plans, especially in the west and south.
