The Best Time to Visit Southeast Asia — Climate Planner
We’re often asked, “What’s the best time to visit Southeast Asia?”
While the answer can be somewhat nuanced, the good news is that there’s no bad time. Southeast Asia benefits from a tropical climate — the entire region is within the tropical and subtropical climatic zones.
While it can and does rain, there is no wrong time to visit. Beautiful beaches, pounding parties, epic jungle treks, and jaw-dropping mountain vistas await whenever you plan your trip.
This climate guide to Southeast Asia breaks down each country, season by season, allowing you to pick the best time for your backpacking adventure!

Southeast Asian Climate — Season by Season 📅
While large areas of Southeast Asia tend to follow similar weather patterns, there are some unusual microclimates and alternative rainy seasons to watch out for. Don’t worry, we’ll point those out!
The following table provides a rough guide to climates across Southeast Asia. It has been designed as a quick visual aid – please bear in mind that there is more nuance than we can depict in a table.
Key:
- Wet season: 🌧️
- Dry season: ☀️
- Burning season: 🔥
- Peak season: ✅
As a general rule, Thailand, Laos, Cambodia, Vietnam, Myanmar and the Philippines experience three seasons a year:
- Dry season – November to February
- Hot season – March to May
- Wet season – June to October
Malaysia, Indonesia, Singapore and Brunei tend to only have two seasons, lasting around half the year each:
- Wet season – October to March
- Dry season – April to September
Rainy Season In Southeast Asia ⛈️
When planning for your first trip to Southeast Asia, it’s easy to panic about monsoon season. But honestly, you don’t need to worry about it too much. Sure, the rain can be heavy (and we mean really heavy at times) but across most of the region, the rainy season doesn’t mean constant rain for weeks on end.
Contrary to common belief, the wet season can be an excellent time to travel! The rain tends to fall predictably for a few hours at a time, leaving the rest of the day bright and fresh. The rainy season is generally cheaper, there are fewer people and you still get hours of cracking weather each day — just remember to carry a poncho in case you get caught out!
A Changing Climate 🌡️
It’s worth noting that due to climate change and the unpredictable El Niño and La Niña cycle, weather patterns across Southeast Asia are becoming less predictable. The information in this article is based on typical weather across the region, however the once-consistent cycle is changing. With the world likely to continue warming until at least 2050, this is only going to get worse.
Best Time To Visit Brunei
Brunei sits close to the equator and enjoys year-round warm temperatures, hovering around 30°C. Humidity levels also remain high throughout the year.
October to February
During Brunei’s rainy season thunderstorms are common and some flooding occurs. While this isn’t a bad time to visit the city it’s not the best time for wildlife-spotting in Brunei’s sprawling jungle.
March to September
March brings fewer showers and the start of the dry season. These months are great for jungle trekking and wildlife experiences. May and June are the height of fruiting season and the best time to see orangutans in the wild. 15 July marks the Sultan’s birthday, celebrated with two weeks of festivities.

Best Time To Visit Cambodia
November to February
Dry season in Cambodia is the most comfortable time for tourists. It’s the driest and least humid time of year with temperatures rarely exceeding 30°C. Visit early in the season to see Tonlé Sap — the largest freshwater lake in Southeast Asia — at its fullest.
March to May
Temperatures rise across the country, often reaching 35°C. You can still expect to see a lot of tourists, especially around famous sites like Angkor Wat. If it’s within your budget, rooms with air conditioning will ensure you can sleep through the sweltering nights.
The Buddhist New Year is celebrated in April and is marked by a huge water fight — the perfect way to cool down!
June to October
Traditionally, Cambodia’s rainy season starts in June but more recently, the shifting climate has brought rain to Cambodia as early as May. Temperatures reach a low of 20-25°C, and the country bursts with greenery.
Hostels and other accommodation options tend to be cheaper during the wet season. There are also much smaller crowds and some less popular spots will be almost deserted. Note that September and October are the wettest months and the rains can cause floods and landslides making getting around more tricky.

Best Time To Visit Indonesia
A nation made up of islands, Indonesia covers a massive area. Each island experiences slightly different seasons. This guide is an overview so you should check with local sources if you’re travelling near the beginning or end of a season.
Almost all of Indonesia is on, or near the equator. This means it’s pretty much always warm at sea level. At higher elevations, you can expect the temperature to drop.
October to March
Sumatra, Java, Bali, Lombok and the Gili Islands are most affected by the wet season, with the heaviest rains falling in January and February. Boat trips and dive excursions are often cancelled due to rough seas. For safety reasons, the popular Lombok to Flores boat trip doesn’t run between December and March.
Accommodation and tour prices are often lower during the wet season. It rarely rains all day, and you can still expect to catch a few hours of sunshine between showers.
April to September
Dry season in Indonesia is the best time for water-based activities like diving, boat trips and surfing. It’s also an excellent time of year for trekking. Wildlife is easier to spot during this period, and orangutans tend to venture to the edge of the forests.
July and August are the busiest months, and accommodation can get booked up in advance. It’s worth planning ahead if you’re travelling during these months.

Best Time To Visit Laos
November to February
With temperatures around the mid to high 20s, dry season is the most comfortable time to visit Laos. It coincides with European winter so you’ll cross paths with plenty of tourists looking to escape the cold back home. Boat travel is excellent during this time as the rivers are full but not gushing. Trekking is popular, especially in the north.
March to May
Temperatures consistently reach 35°C or higher during March, April and May, the hottest and most humid months of the year in Laos. Physical activity can be hard due to the heat – we definitely recommend getting a room with air-con! Temperatures are generally lower at higher elevations so this is an excellent time to visit the Bolaven Plateau.
Slash and burn farming (burning season) is in full swing during the hot season so prepare for reduced air quality during this time. Northern Laos is best avoided during the burning season.
June to October
The rainy season can arrive as early as mid-May but traditionally doesn’t start until June. The rains in Laos tend to be short and sharp, especially at the beginning of the wet season. Around August the rains reach their most intense and little of the country is spared. Expect temperatures to drop to the low 20s or lower at higher elevations. October is the best time of year for budget backpackers who want to avoid most of the rain but still travel on a shoestring!

Best Time To Visit Malaysia
Malaysia experiences different weather patterns and the best time to go will depend on where you visit.
November to March
Malaysia’s capital, Kuala Lumpur, and the west coast experiences excellent weather during this period. Temperatures hover around 30°C and tourists head to Penang and Langkawi.
It’s a different story on the east coast, which is battered by the Eastern Monsoon during this period. The popular Perhentian Islands are effectively off-limits to travellers from November to February. Boats stop running during this time as the seas are rough and dangerous. Most accommodation options and dive schools close during this time too.
March sees the weather improve on the east coast with islands like the Perhentians and Tioman opening up again.
April to October
The weather is excellent across Malaysia from April through August. Snorkelling and diving trips begin in earnest by May and the east coast is a hive of tourist activity. July and August see prices rise throughout the country as this time coincides with school holidays.
September and October bring some rains to KL and the west coast but temperatures remain pleasant. These months also coincide with burning season and aren’t the best time to visit this region of the country.
Malaysian Borneo
Malaysian Borneo, or East Malaysia, has a different high season, with April to October being the dry season. This is the best time to visit Borneo if you want to see wildlife, including orangutans who venture out of the jungle around this time, making them easier to spot. 🦧 The two states of Sabah and Sarawak vary in weather again, with Sarawak being the wettest of the two. Make sure you bring a rain jacket if you are visiting during rainy season!

Best Time To Visit Myanmar
November to February
As with much of Southeast Asia, Myanmar’s dry season is the most popular time for tourism. Temperatures are a comfortable 25°C in the highlands but can exceed 30°C in other parts of the country. Water levels remain high from the rainy season so this is an excellent time of year for river travel in Myanmar. Expect to see plenty of European travellers escaping the bleak winter back home.
March to May
This is the hottest time of year in Myanmar, with temperatures regularly exceeding 40°C in some areas. There are a ton of festivals throughout this period so booking accommodation in advance is recommended. You won’t find many Western travellers in Myanmar at this time but domestic tourism is huge!
June to October
By mid-June, most beach resorts in Myanmar begin shutting up for the wet season. Temperatures hover around 30°C but as the rains arrive, road travel becomes challenging across much of the country. As the roads become impassable, rivers become the most effective way to travel. By the end of the season, temperatures can drop as low as the mid-20s making for a comfortable travel experience.
Rainy Season in Myanmar 🌧️
Rainy season in Myanmar can get particularly intense, especially in the south of the country with huge downpours, the threat of typhoons and many roads being flooded. We would probably avoid travelling to the south of Myanmar during rainy season as it’s not a very pleasant time to travel and mosquitos are at their worst during this time.

Best Time To Visit The Philippines
You can’t talk about the weather in the Philippines without mentioning everyone’s go-to fact: The Philippines is made up of over 7000 islands! This means weather varies across the country, and shoulder seasons can be unpredictable. The following seasons are the general rule of thumb but be prepared to check locally for more exact information.
November to February
As with most of Southeast Asia, the dry season is considered the best time to visit the Philippines. The weather is at its coolest, hovering around the mid to low 20s across most of the country. This is a great time for beach lovers as the rains are few and far between. This is also a good time to surf in the Philippines.
Be prepared for a ton of local festivals and celebrations stretching from January through May. You may need to book accommodation in advance to ensure your bed.
March to May
The Philippines can be scorching this time of year. Average temperatures range between 28-33°C across most of the country. Higher elevations and coastal areas receive some respite from the worst of the heat.
Holy Week takes place around Easter. This is one of the Philippines’ largest celebrations with accommodation and transport being booked up far in advance. This can be both a good and bad time to travel. Cultural immersion will be at its best but travelling on public transport and finding a bed can be hard.
June to October
For the early part of the wet season, rain is intermittent, and there are still plenty of sunny days to be found — this is especially true in the southern regions where beach holidays are still possible.
Typhoon season starts in earnest from August through October. It’s not advisable to travel around the Philippines during this time as disruptions to roads and boats are common. If you are travelling, keep an eye on local news for information on delays and disruptions.
Good to Know! 🏝️
The far southeast of the Philippines experiences a different weather pattern to the rest of the country. This means that the popular island of Siargao has a different wet season — a fact that catches many visitors out! The rainy season here runs from around October until February and dry season is March to September, the opposite to most of the rest of the country.

Best Time To Visit Singapore
Being a mere stone’s throw from the equator, Singapore never gets cold. Temperatures float between 24-32°C all year. Humidity tends to be around 70% all year too.
November to January
This is when the weather is at its wettest and it’s well worth carrying an umbrella or poncho. Thankfully, Singapore is so well constructed that there are rarely disruptions in the city.
Chinese New Year falls during these months (usually late Jan/early Feb). Expect some markets and shops to be shut — especially in Chinatown — but most tourist attractions will still be open.
February to August
As the rains start to recede and the temperatures begin to rise, tourists flock to the city. The dry season is one of the busiest times in Singapore (February is peak month).
Rains are still possible until April, but they’re generally predictable, with afternoon thunderstorms.
September to October
Formula 1 tends to take place in September which can make Singapore unbearably busy — and even more pricey — if you’re a fan of the sport, this could be a once-in-a-lifetime trip. If not, avoid it! September also sees some major Singaporean festivals. Temperatures tend to hover around the low 30s. The shoulder months of September and October also coincide with the burning season in this part of Southeast Asia and smoke and haze from slash-and-burn farming in Sumatra, Indonesia, can cause a significant drop in Singapore’s air quality.

Best Time To Visit Timor-Leste
Coastal areas in Timor-Leste are hot year round with temperatures around 25-30°C, but the mountainous regions can be considerably cooler.
December to May
The rainy season in Timor-Leste can cause flooding and road closures making travel tricky. Water visibility is also affected so it’s not the best time for snorkelling and diving. Culture vultures and foodies will enjoy the Festival of Culture and Food in March showcasing the country’s culture and cuisine.
June to November
Timor-Leste’s dry season starts slightly later than that of its Southeast Asian neighbours. The hot, dry days are the ideal time for exploring on land. These months are also the best time for underwater adventures off the coast of the capital Dili and diving the coral reefs around Atauro Island. The annual coffee festival creates a buzz around September or October.

Best Time To Visit Thailand
November to February
Peak travel season in Thailand once again coincides with the European winter and Christmas period. Travelling during this time means rubbing shoulders with a ton of other travellers.
Temperatures are cooler than during the hot season but they still regularly reach 34°C. Thailand’s west coast gets more than its fair share of sun, making this an excellent time for beach lovers. However, Koh Samui and other nearby coastal spots can experience high levels of rainfall during this period.
March to May
Temperatures regularly make their way up to 40°C during the hot season. Physical activity can be challenging and air conditioning is recommended if it’s within your budget!
Songkran and Chinese New Year take place during these months. It’s worth paying attention to when these are, as accommodation and transport often need to be booked in advance during this time.
June to October
The start of June still tends to deliver glorious sunshine to most of the country, but by the end of the month marks the start of the rainy season across most of Thailand.
Beach resorts, coastal hostels and tour providers start to close around August as the north of Thailand begins to experience heavy rain. However, cast coast spots and the Gulf Islands, like Koh Samui, still offer a dose of vitamin D for sun worshippers — just be prepared to dodge the odd shower!
This rain continues throughout September and into October, which can make travel less enjoyable. On the other hand, the weather means fewer tourists and less competition. You can find some really good bargains during these months.
Rainy Season in The Gulf of Thailand 🌦️
The islands of Koh Phangan, Koh Tao and Koh Samui have their own rainy season from October to December. During this time, it is still hot with long downpours, but transport can be disrupted, and power cuts are not uncommon. This is not a great time to visit these islands if you want to dive as underwater visibility will be at its worst.

Best Time To Visit Vietnam
Due to the shape and topography of Vietnam, you’ll find differing weather patterns depending on the region you visit.
December to February
Mainland Southeast Asia’s traditional dry season sees most of Vietnam experiencing dry conditions but the central region experiences heavy showers. Typhoons are not uncommon around Hoi An during this time.
It’s warm in the south and beaches are busy. This is also a great time to visit the Mekong Delta. However, temperatures in Northern Vietnam are much lower (rarely exceeding 20°C) and can even drop into single figures at night so pack a jumper!
March to May
Rains across the country disperse, and Vietnam sees an explosion in tourism. Beaches across the nation welcome visitors and Halong Bay is at its most appealing with clear blue skies and very little haze.
It’s hot season in the south and the northern regions warm up with temperatures reaching the low-to-mid-20s. This is an ideal time for trekking in Sapa or taking on the Ha Giang Loop!
By the end of May, it’s common for areas in the north and south to experience predictable afternoon showers.
June to August
While the rainy season begins to batter the north and south of Vietnam, it’s generally dry and sunny in the central region. Rainfall is almost non-existent, and temperatures float between the mid-20s and low-30s. However, the central highlands can still experience some extreme weather so trekking in the mountains isn’t recommended.
September to November
The rains return to the central region; storms are frequent, and transport can be disrupted. It remains wet in the South through October and there’s a risk of flooding in the Mekong Delta. The north sees a great improvement in the weather and these are great months for trekking.
