Southeast Asia lies within the tropics, with southern areas close to the equator, and so it's warm all year round. Average temperatures are around 27°C (80°F).
The climate varies significantly across the region of Southeast Asia. This makes it a year-round travel destination. The best time to visit will really come down to which country you would like to visit and what you want to do.
Generally speaking, the best time to visit most places in Southeast Asia is from November to February when the weather is dry (driest) and warm (on average). Wet-season monsoon rains fall from June to October in most SE Asian countries.
Southeast Asia Weather Guide
Not all countries in Southeast Asia share the same seasons at the same time. There are some regional differences. They are roughly divided into two weather patterns.
There are three main seasons in Thailand, Laos, Vietnam, Cambodia, Myanmar, and the Philippines:
- Dry season: November to February
- Hot season: March to May
- Rainy season: June to October
There are two main seasons in Malaysia, Indonesia (Bali), and Singapore:
- Dry season: April to September
- Rainy season: October to March
Most travelers choose to visit mainland Southeast Asia during its dry season as it's not so hot with little rain. During this time, go to the busy places as early or late in the peak season as you cann to avoid the crowds, such as the Grand Palace in Thailand and Angkor Wat in Cambodia.
The weather in the hot season, consistently getting to around 38°C (100°F). But it is a good time for the water fun at the beach.
The rainy season is not so good, but you will find fewer crowds and lower prices for flights and accommodation. Travel to Southeast Asia in Summer: Places to Go, Costs, Weather

Best Times for Beaches in Southeast Asia
- Thailand and Vietnam: November to early April
- Indonesia and Malaysia: April to October
Phu Quoc Island in VietnamIf you hope to enjoy sunbathing and swimming in the sea, generally speaking, the best time to visit Southeast Asia's beaches is from November through early April when the weather is usually sunny and dry, and it's not too hot or too cool. The beaches in many countries, such as Thailand and Vietnam, are at their best during this period.
But if you would like to enjoy your beach vacation in Indonesia (like in Bali) or Malaysia's east coast (like on the Perhentian Islands or Tioman Island), the best time to go is between April and October.
If you're traveling to the beaches during the wet season, you should expect some rainy days, but there will also be days where it only rains for a short while and then the sun comes out. You'll find that hotel and resort prices are considerably cheaper during the rainy season.
Worst Times to Visit Southeast Asia
June to October is the rainy season and is generally considered to be the worst time to visit Southeast Asia. There will be some discomfort or inconvenience if you travel during these months.
However, these worst times for the travel trade have benefits. You can enjoy very reasonable price and less-crowded beaches and temples. In addition, as the rain in Southeast Asia is so predictable (it usually rains in the afternoon and at night), it's easy to plan around the weather. This means there's not so much of a problem in traveling to Southeast Asia during the off-season, as long as you know what to expect and plan well.
If you are visiting northern Southeast Asia (Thailand, Laos, Vietnam, Cambodia, Myanmar, and Philippines) and particularly concerned about the weather, we would like to suggest you avoid April (the hottest month) and September (the wettest month). For dry experiences, you could visit Singapore and Bali instead, which enjoy the best time from April to October.
