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.

Best Times to Visit Thailand
Generally, the most popular time to visit Thailand is between November and early April when it is the cool and dry season. The best time to visit Southern Thailand depends on which coast you're heading to.

- East Coast (Koh Samui, Koh Phangan, Koh Tao): The best weather lasts from January to September, with the driest months between February and August. The monsoon season hits hardest in October to December.
If you're only visiting Thailand once, make it November for the Yi Peng Festival, the world's most breathtaking lantern release. Watching thousands of lanterns illuminate the sky is a magical, once-in-a-lifetime experience you won't want to miss!

Best Times to Visit Singapore
Singapore is a wonderful year-round destination with good weather. Unlike many destinations in Southeast Asia, there isn't that much of a difference between the wet season (October to March) and the slightly drier summer season (April to September).
You might find it strange that the peak season is from November to early January even though there is some rain and it is a little wet. Singapore is crowded with travelers, particularly during Chinese New Year.

Best Times to Visit Cambodia
Weather-wise, the best time to go to Cambodia is between November and April when it is sunny and dry. It is perfect if you are going to spend some time on a beach or hike through the jungles of Cambodia.
If you want to experience the country's fresh and lush greenery and quiet temples, the wet season (May to October) can be a good time. Heavy rains can occur but they only last for 1 or 2 hours in the afternoon.
Best Times to Visit Myanmar (Burma)
The best time to visit most of Myanmar is from November to February when there are warm and dry days.
If you intend to visit areas in and around Mandalay and Bagan, which are the hottest and driest regions of Myanmar, you'd better avoid March to May as temperatures can rise to over 40°C/104°F. The wet season from June to October is considered a good season even though there is a bit of rain and it is good to avoid the winter crowds.
Best Time to Visit Laos
Laos, a small and landlocked country in Southeast Asia, has a dry season (October to late April) and a wet season (May to late September).
If you are looking for warm and dry weather and want to enjoy outdoor activities, the ideal months to travel in Laos are from November to January, with temperatures ranging from 14–26°C (57°–79°F). This is also an excellent time for exploring the Mekong River.
Best Times to Visit Malaysia
Malaysia has a classic equatorial climate with plenty of sunshine, high temperatures, and wet months throughout the year.
The best month to visit Malaysia depends on which side of the country you are going to visit. The seasons on each side of the peninsula are different.
The best time to visit the western islands is from December to February, while the perfect time to visit the east coast is from June to August.
Best Times to Visit Indonesia
Indonesia is a year-round destination with warm tropical temperatures averaging 28°C/82°F throughout the year. The dry season in Indonesia spans from May to September and the wet season is between October and April.
If you plan to dive off the coast of Bali, Lombok, and Komodo National Park or want to plan to climb one of Indonesia's many volcanoes, the dry months from April to September are a great time.
If you are looking for good weather as well as fewer crowds, you can visit Indonesia in May, June, and September.
