Best time of year to go to Myanmar

Some of the activities are good all year round, no matter how the weather is. Below is the list of some highlighted things to do that you should not miss when visiting Myanmar and the best time for it.

Shwedagon Pagoda

• Type: Classic visit
• Best time: November to April

No visit to Yangon is complete without a visit to one of the most famous pagodas in the world. It is like the Eiffel Tower of Yangon—Yangon being the main commercial city of Myanmar. This massive golden icon can be seen from most rooftops in the city. In fact, many clubs and bars seek out prime rental spaces and shell out extra money for a view of this place. It is a symbol of pride for the people of Myanmar.

A visit here is absolutely breathtaking and magical. There are four entrances, each leading up a flight of steps to the pagoda’s platform. There are also eight planetary posts, one for each day of the week (Wednesday is split in two). Burmese Buddhists will go pray at the respective post where they were born. Each planetary post is ruled by an animal - garuda for Sunday, tiger for Monday, lion for Tuesday, tusked elephant for Wednesday morning, tuskless elephant for Wednesday afternoons, mouse for Thursday, guinea pig for Friday and naga for Saturday. The price for the pagoda is 8,000 kyats (US$6) for foreigners, and opening hours are 04:00 – 22:00 hrs (seven days a week).

Exploring the famous Inle Lake

• Type: nature and culture
• Best time: whole year

The leg-rowers of Inle Lake will bring joy to any traveler. Riding in a long, skinny boat powered by an engine and boat driver at one end, tour-participants on this ecologically rich lake will go to silversmiths, silk weavers, and pagodas at Indein. Visitors find this idyllic place to be a sanctuary after long days of traveling and trekking around Myanmar. Stay in a hotel on stilts or in the nearby town Nyaungshwe for access to delicious local and international restaurants.

Diving in the Myeik Archipelago

• Type: adventure
• Best time: November to April (peak around December to February)

This stretch of land around Myeik is surrounded by unexplored corals, fish and sea life. Several diving companies feature liveaboards where tourists can island hop, snorkel, and scuba dive to their heart’s content. Cruises and tour packages are available, since getting around isn’t easy.

Take a ride in a hot air balloon

• Type: Adventure
• Best time: Whole year in Inle Lake, November to February for Bagan

Go up in a basket and float into the sky. See the pagodas below. Not for those with a fear of heights or backpackers on a budget, because these rides don’t come cheap. But if you have money to spend, a hot air balloon ride over Bagan (or Inle Lake) is as mystical and wonderful as it sounds. Prices for these rides range from U$300–U$400.

Trek in Kalaw

• Type: Adventure
• Best time: Whole year

Typical treks through Kalaw, the hill station in Shan State just minutes from Inle Lake, run from two days to a week. They work with local families to arrange homestays, which includes home-cooked local meals. Trekkers will see lots of green and see a completely different side of Myanmar, away from pagodas and dust. Multiple trekking companies arrange tours that are relatively inexpensive.

Some of the festivals do not wait until the good weather to come, and you need to come for it. Let’s check more detail below.

Myanmar Harvest Festival (February)

Held during the eleventh month of the Burmese calendar on the day of a full moon, this festival celebrates the beginning of the harvest season with glutinous rice specialties prepared and enjoyed throughout the country with families and friends gathering together.

Myanmar Shinbyu Ceremony (March or April)

During the school holidays between March and April young boys from villages and towns across Myanmar will dress as princes and walk to their local monastery where they will spend a short time studying the Dhamma - the truth taught by the Buddha. Villagers join the colourful procession and communal feasts are prepared.

Myanmar Thingyan Festival – Myanmar New Year (mid-April)

The traditional new year festival is one of Myanmar’s best-known celebrations. Most restaurants, shops, and business will be closed, and transportation and hotels will be harder to come by and raise prices. However, visiting during Thingyan is a once-in-a-lifetime experience.

Over a range of 4-5 days, music, dance, and the game of water-throwing can be seen everywhere, especially on the second day (akya nei). Villagers celebrate casually with family, while those in cities deal with heavy traffic to come together in large, bustling crowds.

If you’re a thrill seeker, nothing can compare to the water throwing in Kandawgyi Park, Yangon. In the largest game in the country, young people spray each other with hoses as music blasts throughout the city. Even if you choose to celebrate in Bagan, Mandalay or Inle, be prepared as children everywhere get involved in the game and you’re bound to get soaked! If someone pours water on you, the best thing to do is pour water on them in return in order to return the favor of “washing their soul” for the new year.

Shwedagon Pagoda Festival (late February until early March)

This five-day event leads up to the full moon with people from all over Myanmar visiting the Shwedagon Pagoda in Mandalay with offerings of water, candles and flowers.

Phaung Daw Oo Pagoda Festival (October)

The splendid pagoda next to Inle Lake contains five sacred images of the Buddha. During this festival, decorated royal barges carry four of the images and circle across the lake as pilgrims gather to celebrate. One image remains, as it was once lost in the lake and thought to have brought about bad luck. Boat races also occur, with up to 50 rowers competing at once. If you are interested in Burmese culture and religion, you will surely be in for a treat at Phaung Daw Oo Pagoda.

Tazaungdaing Light Festival (November)

One of the largest and oldest festivals in Myanmar, Tazaungdiang (Tazaungmon full moon) can last up to 18 days. Buildings all over Myanmar are lit up and decorated. Some locations will have their own special customs that are definitely worth experiencing. At Shwedagon Pagoda, yellow monk’s robes are woven and worn. At Taunggyi, hot air balloons in all shapes and sizes are released at night to the melodies of traditional Shan music.

Taunggyi Balloon Festival (around mid-November)

The capital of the Shan State is home to an annual balloon festival with dozens of decorated paper balloons are released into the sky. The balloons can reach 15-20 feet in height with lanterns inside so that they glow at night. Firecrackers are also attached to the balloons for a noisy spectacle.

Now, we will come to more detail about Myanmar weather

In general, Myanmar is a tropical country in Southeast Asia, whose climate is affected by the annual patterns of the monsoon. Temperatures and rainfall levels depend on the season, and also differ between highland and lowland locations. On average, the northern, mountainous region is the coolest, while the delta and coastal regions are the wettest.

Despite being off the radar for most tourists, Myanmar has a fairly steady climate. As in many other equatorial Asian countries, Myanmar has two broad seasons: the dry season and the rainy season. (The dry season can then be further divided into the cool and hot seasons for a total of three distinct seasons.)

With pleasant temperatures, less rainfall, and several festivals, the dry season is a great time to visit anywhere in Myanmar. Bagan, Mandalay, and other central plains regions will rarely see rain. If you plan to visit multiple regions, the consistency of the dry season will make travel easier.

The cool season in Myanmar is the most comfortable, with mild temperatures ranging from 70-80℉ (20-30℃) depending on the region. Overlapping with the winter holiday season, this is one of Myanmar’s busiest times for tourism. We recommend planning your trip in advance during these months to ensure you get the hotels of your choice. Despite Myanmar’s overall warm weather, bringing a few extra layers for the evenings or sunrise watching is highly recommended. Some areas, especially in the central plains (Bagan) and the eastern region (Inle Lake area), can dip down to 50℉ (10℃) at night and through the early morning.

As the cold and dry season ends at the end of February, temperatures start to climb. The heat reaches the central plains region first, which can result in highs up to a scorching 100℉ (40℃) at this time. In addition, the continuing dryness combines with warm air to create clouds of dust. If you visit Myanmar during the hot season, going to any of the numerous beaches is a good idea.

From June to October, Myanmar is wet and humid. The beginning of the season will see some of the highest temperatures of the year: average highs in Mandalay and surrounding upper interior regions remain around 95℉ (35℃). Precipitation is common, especially in the coasts, delta, and mountains outside the central plains.

Downpours often occur, especially at the height of the season from July to September. Roads can sometimes become washed out, making travel difficult and inconvenient. Although rare, there also exists the risk of larger flash floods. It’s good to check on these conditions before traveling to Myanmar during these months.

That being said, you can still have an enjoyable experience visiting Myanmar in the rainy season if you plan well. First off, know what places will be worth your time. Beaches like Ngwe Saung and Ngapali will be closed at this time, as will most southern resorts and activities. Heavy downpours hit hard in Dawei, Kyeik, and Kawthaung, while Hpa An, Mawlamyine, and Golden Rock will see slightly less intense but still ever-present rainfall. Instead, visit the temples of Bagan, Mandalay, Inle, and other interior central regions.

Monsoon rains also revitalize flora and fauna, and miles of green landscape cover the countryside. This means that if you manage to come across a drier day or are willing to handle slippery routes, trekking can be a great option to explore the surrounding nature.

Second, arrange most of your activities in the morning, when rain is less common and the weather is more pleasant. The end of the rainy season will see cooler temperatures and less rain, as well. If you’re able to visit in October, conditions will usually be much more in control and you will avoid peak season crowds.

The country is on the path of typhoons and tropical storms and is particularly affected between mid-July and mid-October. With the modernization of infrastructure and weather alerts, there is no major danger.

Do not forget that the rainy season does not mean it is raining all day and contrary to what we believe, these rains are nourishing and bring life in Myanmar!

January

This is peak season for travelling to Myanmar. The weather is hot and dry, making for lovely conditions throughout the country. River levels are still high enough for boat travel and the beaches of Nagapali enjoy hours of sunshine, while the chill in the foothills begins to lessen.

March

Temperatures in the country continue to rise and it is often best to keep mid-afternoon exploration to a minimum. Rainfall is still non-existent, and accommodation still fills up quickly, so again it is best to book far in advance.

April

April brings with it some of the hottest temperatures of the year, reaching over 40°C in some regions, and crowds flock to the country as it celebrates its New Year in the middle of the month. Rainfall is still at a minimum and it is advisable to book far in advance.

Events & Festivals

May

The searing temperatures continue for much of May, but begin to return to normal towards the end of the month as breezes and rain showers set in. There are fewer crowds at this time, and although you may experience the odd shower, this can be an excellent time to visit Myanmar. You may also be able to take advantage of shoulder season hotel offers.

Events & Festivals

• Full Moon Day of Kasone/Buddha Day (between mid-April and early May): Celebrates the birth and enlightenment of Buddha at the foot of a banyan tree. People pour water individually and collectively on this day in recognition of the banyan tree's preservation.
• Shit-Thaung Pagoda Festival - Mrauk U (May): An eight day festival held at the pagoda, featuring boat racing, traditional wrestling and water splashing in Mrauk U's canal on the full moon day.

June

Visitor numbers continue to reduce and temperatures hover around the 30°C mark; although it can still be hotter in the central plains to the south of Mandalay. Weather can be unpredictable at this time of year, but showers are usually short-lived and shouldn't impact on your overall experience. However, most beach resorts close by mid-June in preparation for the unfavourable weather expected in the coming months.

Events & Festivals

• Thiho Shin Pagoda Festival - Pakokku (June): A typical Upper Myanmar festival, with traditional plays and dancing entertaining locals and visitors alike. Local products such as tobacco and Thanaka logs are also sold at the event.

July

Rains begin to hit Myanmar's southern coast and the beaches at Nagapali are now closed up. Better weather can be found in the northeast of Myanmar, where low visitor numbers and stunning scenery can be massively rewarding. This is peak time for cruising along the Chindwin River, but road travel across much of the country becomes difficult.

Events & Festivals

• Chinlone (Cane Ball) Festival - Mandalay (June to July): Lasting for almost a month, this festival sees hundreds of chinlone teams compete in the traditional sport of Burma to live music.
• Full Moon Day of Waso - start of Buddhist Lent (July): During the month of Waso, Buddhist monks are forbidden from making a journey lasting more than one day, instead devoting more time to Buddha's teachings. Locals offer robes and alms to monks to gain favour.

August

You should be prepared for heavy rain throughout the country and road travel to rural locations continues to be slow. If you are lucky enough to find a window of good weather, trekking can be extremely rewarding and presents wonderful opportunities for photography, as it is at this time of year that Myanmar's landscape is at its most beautiful.

Events & Festivals

• Taungbyone Nat Festival - from Mandalay (August): A major gathering place for spiritual mediums, this festival attracts pilgrims and visitors in their thousands to make offerings and enjoy dances and other celebrations in honour of two famous Nats.

Rainfall will start to reduce; especially towards the end of the month, and temperatures drop to the high 20°Cs. This can be a wonderful time to see Myanmar, with fewer visitors and lush green landscapes. However, beaches remain closed and some areas can be difficult to reach by road.

Events & Festivals

• Bo Bo Gyi Nat Festival - Amarapura (late September or early October): A ten day festival attracting large numbers of pilgrims to the pagoda on the shores of Taungthaman Lake, next to U Bein Bridge.

Events & Festivals

Temperatures begin to rise and the country sees very little rainfall at this time of year; although in the highlands and foothills to the east, temperatures are at their lowest, with average highs of 25°C. While not as busy as January to March, this is the beginning of the high season and it is advisable to book far in advance.

Events & Festivals

Mandalay

Due to its location, even in the cool season, Mandalay’s temperatures still remain to be quite hot. According to us, try to plan a trip here from November-January in order to avoid the intense heat. Average temperature during this time is around 27°C. 
In fact, even in the peak of rainy season, Mandalay only receives an average of about 9 days of rain. It is therefore not a bad idea to visit this region during the wet season just to avoid the intense heat from February to April. Moreover, traveling during monsoon means less tourists and lower prices.

Below is the current weather of Mandalay and the 7-day forecast:

MANDALAY WEATHER

Bagan

Bagan have pretty much similar weather conditions as Mandalay. As mentioned during the months of February to April, the temperatures in these regions can become unbearable, especially if you are walking around from temple to temple. If you can, avoid these months and head here in December or January. Otherwise, consider doing all of your temple touring early in the morning or during sunset.

Below is the current weather of Bagan and the 7-day forecast:

BAGAN WEATHER

Yangon

Yangon is best visited from November to April during the time it experiences little rain. Compared to Mandalay, the temperature here is not as hot with an average of 24°C. Although with that being said, the humidity here is higher so similar to Bagan, it is best to do your sightseeing during early morning and sunset.

Insider tip: These times make for the best photos anyways!

Below is the current weather of Yangon and the 7-day forecast:

YANGON WEATHER

Inle Lake

As Inle Lake is located in a relatively higher altitude, even during the peak of summer, the average temperature is around 30°C while during the cooler months, temperatures can drop to 10°C at night. 

If you plan on heading here during the cooler months and hike around, we definitely recommend bringing a light jacket. For more info, you can check our article about packing & clothing in Myanmar.

Mergui Archipelago 

As with much of the rest of Myanmar, November to April is the high season for visiting the Myeik Archipelago. December to February offers the most beautiful and comfortable weather conditions – with warm, sunny weather, steady winds, and calm seas. There is less wind and higher temperatures in March and April, which also makes for clearer waters and the best time for diving and snorkeling.

From May to July there are strong onshore winds and a larger swell (with occasional hurricanes) and the rainy season is from June to October; cruises of the Archipelago do not operate from the beginning of May until the beginning of October. If storms do arrive during the monsoon, the region has numerous large islands which provide protected anchorages at any time of year – and in general the area provides safe sailing, with few dangerous reefs or obstacles. 

Below is the current weather of Mergui Archipelago and the 7-day forecast:

MERGUI ARCHIPELAGO WEATHER

Vietnam

The best time of year to visit the whole Vietnam is spring (February to April) and autumn (September to November). The temperatures are more moderate, and rainfall is lighter. In spring, March and April have the lowest rainfall across all destinations and temperatures are pleasant, though still cool in the far north.

It is the fact that Vietnam is a year-round destination. Every time of year, you can always find the sun somewhere (more or less).

In the broadest sense, the best time to visit Vietnam and Myanmar is from November to February. This is because temperatures and humidity falls across central and northern Vietnam and rainfall becomes less frequent in both Vietnam and Myanmar.

Here is more detail about where and when to visit Vietnam throughout the year.

Thailand

Although the climate varies throughout Thailand, you can visit all year round. The best time to visit Thailand is during the cool and dry season between November and early April. In the south, the climate differs between the eastern and western coasts. 

The west coast is more favorable during the winter months, when diving and snorkeling will be at its best. The weather on the east coast is good for most of the year, with the lowest rainfall in January and February and the highest in November.

In case you want to combine Myanmar and Thailand, the best time to do so is from November to February since it has perfect weather throughout all the countries.

Here is more detail about where and when to visit Thailand throughout the year.

Cambodia

Cambodia is a year-round destination, so the best time to visit the country depending on what you’re looking for. 

Most travelers visit Cambodia from November to March. If you prefer to dodge the crowds and go when prices are lower, the best time to visit Cambodia is from May to early October.

Cambodia is warm year-round with temperatures rarely dipping below 68°F (20°C), wherever you go. Seasons are broken into wet and dry season. Wet season, from May to October, is usually marked by a brief downpour in the afternoon. This rarely affects travel plans and still includes many hours of bright sunshine. It is known locally as green season as the countryside springs to life. 
Travel in the dry season, from November to March, is marked by hot dry days. 

The best time to combine the two country is no doubt around November to February

Here is more detail about where and when to visit Cambodia throughout the year.

Laos

The small, landlocked country of Laos is best visited between late October and early April, when the weather’s warm and dry throughout.

River travel is best between November and January, when high water levels make passage easy along Laos’ main waterway, the Mekong River. Visiting the Bolaven Plateau is also pleasant at this time of year.

Laos’ geography plays a major part in shaping its climate, and cool temperatures can still be found in the highlands, which lie mainly in northern, eastern and central regions.

The ‘green season’ falls between late May and October, when the rains return to the country.

However, showers are usually short and sharp, having little impact on your exploration. At this time of year, the country comes to life, with waterfalls beginning to flow once more and the lush scenery attracting a variety of wildlife.

If you plan to visit the two countries, the months from November to February are the best for you. With very similar climates, and only a few differences in the seasonal changes, deciding when to visit both places together can be a lot easier.  

Here is more detail about where and when to visit Laos throughout the year.

What is the best month to visit Myanmar?

The best time to visit most of Myanmar is from November to February as it is neither too hot to walk around due to the cool breeze that blows in. 

What is the worst month to visit Myanmar?

In a nutshell, although you can visit Myanmar all year round, due to its tropical climate. However, as a general rule, try to avoid visiting Myanmar from June to September. During this time (especially from July to September), the wet season is in full swing. Places like Ngapali Beach during this time even closes due to inaccessible roads.

What is the cheapest month to fly to Myanmar?

Logically, the cheapest time to fly to Laos is during the off-season from April until October. As there are not many tourists visiting the country, the airlines and hotels seem to offer promotion to attract more tourist and try to fill-up the plane. If you are ok with the heat and some sudden rain, this is the time for you.

According to cheapflights.com.au, the cheapest flights to Laos are usually found when departing on a Monday. The departure day with the highest cost is usually on a Friday.

Moreover, Myanmar flights can be made cheaper if you choose a flight at noon. Booking a flight in the morning will likely mean higher prices.

Simply follow this, sometimes you can have the promotion of 40-50% discount.

When is the low season in Myanmar?

The low season in Myanmar is the same as the off-tourist season. It starts from April when the country is heated up until the late October when then intense rain is going to stop

When is the rainy season in Myanmar?

The rainy season in Myanmar starts from June until October.  The rainiest months are almost everywhere June, July and August, and on the two coasts, being exposed to the west, the rains are plentiful; in fact, some areas receive more than 1,200 mm (47 in) of rain in a month! Yangon is a bit less rainy because it's located in the area of the mouths of the Irrawaddy River, which are exposed to the south, and receives about 500/600 mm (20/23.5 in) of rain per month during this period, while the central area where Mandalay is located receives only 100/150 mm (4/6 in) of rain per month.
