Like many Asian countries, Thailand also has a tropical climate. The best time to visit Thailand depends on what you are looking for during your trip. One wants sun, sea, and beach while the other wants to walk through a green environment. Whatever you are going to do; one thing is certain; with an average of around 27 degrees Celsius (around 80°F), Thailand is a great place to stay all year round.
Best Time to Visit Thailand
One of the reasons that many people visit Thailand is a wonderful climate. With an average of around 27 degrees Celsius (around 80 °F), that is not surprising. The weather in Thailand can be divided into 3 seasons; the rainy season (June-October), the cool season (November-February) and the hot season (March-May).
It’s always a great idea to check the best time to visit Thailand when you go on holiday/journey. This prevents you from experiencing rain on a tropical island or feeling the extreme heat when you go hiking.
TIP – The cool season is the best time to visit Thailand. These are the months of November to March.

The Seasons of Thailand
As discussed earlier, Thailand’s seasons can be divided into the cool season (high season), the rainy season (low season), and the hot season (in-between season). This is not only due to the weather but also to the crowds and prices of accommodation or highlights. Consider well in advance in which season you want to travel.
November to March
The months of November to March are the best time to visit Thailand. Many people come in this period because it hardly rains and the temperature is pleasant. Prices for accommodations and highlights do rise during this period, especially during Christmas and New Year’s Eve.
March to June
March to June is the hottest period in Thailand and also quite dry. Temperatures rise above 30 degrees Celcius which makes it less suitable for hiking and activities. September and October are ideal months for the north and the Gulf coast of Thailand.
Low Season (Rainy Season)
June to October
These months are the rainy season. The rain showers are often heavy but last no longer than an hour and the weather is good and sunny between the showers. Some islands will be off limits because of the rough sea. Please note that floods can occur.
Thailand Average Weather by Month
Although we have a lot of experience with traveling in Thailand, it is difficult to predict exactly what the best time to travel is, regardless of which country you visit. In addition, the weather can never be fully predicted. To hopefully give you a good idea about the best time to visit Thailand, we have listed the average weather for each month.
This is one of the best (and most popular) months of the year to visit Thailand. There will be favorable weather conditions throughout the country with a pleasant temperature and little rain. Northern Thailand is cool and dry: perfect conditions for hiking. In the south, the weather is often good, and on the west coast, rainfall will be rare. The east coast, such as Koh Samui and Koh Phangan, can have small showers, especially at the beginning of the month.
Places like Chiang Mai, Chiang Rai, and much of northern Thailand are cool and dry, with little chance of rain and temperatures around 25°C (77°F). This makes February an ideal month for outdoor activities that the north is famous for. It also provides a welcome break from the heat in the south. Expect dry weather in Bangkok with high temperatures. In the south, there’s dry and sunny weather with blue skies and little chance of rain. Average temperatures are around 30°C (86°F).
The temperature is starting to rise throughout Thailand. This is especially noticeable in the north where the colder winter months give way to the summer and temperatures can reach up to 35°C (95°F). In Bangkok and the central part of Thailand, you can expect high temperatures and little rain. Visiting the different highlights of Thailand means sweating a lot. In the south, it is dry and sunny. The temperature varies from 25 to 30°C (77 to 86°F). The west coast with Phuket and Krabi is slightly warmer than the east coast.
April can be summarized as hot, with an average temperature above 35°C (95°F). The heat in Bangkok and central Thailand (around Kanchanaburi) can be particularly depressing, making sightseeing difficult. Schedule shorter visits instead of entire days in the sun. Head south to avoid the heat, where the temperatures are slightly lower (30-35°C, 86-95°F). The east coast is best in April as the west coast will suffer from occasional showers.
The best time to visit Thailand runs until April with May being a bit of a transition month. The temperature drops in May. Most (not all) regions experience an increase in rainfall, albeit small and sporadic showers. Khao Sok is warm and wet with high humidity. The islands of Koh Chang and Koh Kood are particularly wet and there is a high chance of rain on the beaches on the west coast. For sunshine, you have to go to Hua Hin and the beaches of Koh Samui and Koh Phangan on the east coast. Despite the chance of rain, May is a great month with lots of sun and low visitor numbers.
Nothing is certain in life, but you have a great chance of rain throughout Thailand in June. Often the rain comes in the form of short showers with periods of good weather during the rest of the day. The advantage of the rain is that nature in the north and central regions is starting to turn green. Khao Sok is hot and wet, Koh Chang and Koh Kood are very wet. There is a high chance of rain on the beaches of the west coast. For sun you have to be on Hua Hin and the beaches of Koh Samui and Koh Phangan on the east coast.
As the month progresses the rainfall increases with short daily showers. There’s a chance for the heaviest rainfall of the year. Hiking is more difficult in the north. The landscape is green and lush, and the rivers and waterfalls are at full strength. The islands of Koh Chang and Koh Kood are very wet. Further south the sea becomes rougher. The west coast also has more chance of heavy rain showers. The east coast is drier and enjoys long sunny periods. July is a popular month for diving around Koh Tao.
The rain reaches its peak in August, with the heaviest rainfall of the year in the north. You can expect rain almost every day on the islands of Koh Chang and Koh Kood, and the beaches on the west coast such as Phuket and Krabi. This is the wettest month of the year for the west coast. Hua Hin and the islands on the east coast such as Koh Samui and Koh Phangan have drier weather conditions with lots of sunshine.
In August there is a lot of rain in the north. But in September there is perhaps the most rain throughout all of Thailand with rain in all corners of the country. Temperatures drop to 25°C (77 °F) and thunderstorms are not uncommon. It is not beach weather in September with heavy rain and a rough sea on the west coast (Phuket, Koh Phi Phi, Krabi, etc.) and increasing rainfall in Koh Samui and Koh Phangan. It is much quieter and cheaper than in the previous months.
In October the weather starts to change, although you can never fully predict it. The rain starts to decrease. In the north, it is “winter” with temperatures of 24 to 27°C (75 to 80°F). When it comes to the beaches in Thailand, the islands of Koh Chang and Koh Kood are the wettest, although rainfall is considerably less than in the previous months. There is still a lot of rain on the west and east coast. However, there are drier days and blue skies in Phuket, Koh Phi Phi and Krabi on the west coast.
In November the rain has almost disappeared, especially later in the month. It is a good month to visit Chiang Mai, Pai, and the north of Thailand with dry, sunny days and pleasant temperatures. In the evening the temperatures in the north can drop. Beach lovers should go to Koh Chang and Koh Kood, with little rain. Hua Hin also has a lot of sunshine and little rainfall. The south and east coast with Koh Samui and Koh Phangan are still in the middle of the wet season, so you better head to the west coast.
Just like January, December is one of the best months to visit Thailand. There’s little rain, favorable temperatures, and lots of sunshine. An average temperature of 25 °C (77 °F) in Bangkok and central Thailand. Hiking in the north of the country is easy to do in these weather conditions. Beach lovers can choose from almost all beaches in December. High temperatures and blue skies are standard. The only region with a lot of rainfall is the southeast (Koh Samui, Koh Tao). The west coast around Phuket, Koh Phi Phi, and Krabi is ideal for diving.
Thailand’s Rainy Season
The rainy season (June to October) is the least predictable season. It is never the case that the sky just breaks open in June and only closes in October. There will be rain on most days, but often only for a few hours in the afternoon or at night. The rain usually gets stronger between June and August, with a peak in September and October, when unpaved roads are turned into mud roads.
Everything in Bloom
The rainy season in Thailand does not necessarily have to be a negative thing. More rain also means that nature turns beautifully green and lush. The months of November and December are highly recommended because the landscape is still green and the waterfalls large due to rainfall in the previous months.

Another advantage of the rainy season in Thailand is that prices drop. Because fewer people come, many accommodations have trouble filling up their rooms. This means you can easily negotiate the price. Sometimes you can even save more than half!
A Change in the Weather
The best time to visit Thailand is never easy to determine. Certainly in recent years there have been more and more changes in the weather. Where in the “past” you were almost certain of having nice weather in the cooler months (November to February) and it rained in the rainy months; that is no longer the case. Heavy rainfall and floods can, unfortunately, occur throughout the year nowadays. It is no longer that easy to predict.
Therefore, always check the weather forecasts before you go anywhere. The cool, dry season is no longer always cool and dry, and the rainy season doesn’t just mean rain.
North, Central, and South Thailand
Thailand is, just like Vietnam, a vast country. The best time to visit Thailand can be split into north, central, and southern Thailand. Transport in Thailand is well organized so there is a good chance that you will see a lot of Thailand during your trip. If you know the best time to travel per region, you can adjust your travel route accordingly.
Best Time to Visit Northern Thailand
The higher altitude, less humid north, experiences the biggest difference in temperatures. At night the temperature can drop to 0 degrees Celsius (32°F) in the cool season while the region is often warmer than the rest of the country between March and May.
The north of Thailand with its special nature and culture is certainly worth a visit. The cities of Chiang Mai, Pai, and Chiang Rai are the main attractions. If you don’t like rain you should avoid northern Thailand in the months of June, July, and August.
Green and Lush Environment
Keep in mind that the environment is not at its best in the dry, cool months (November to February) because less rain has fallen. The north is beautiful when nature is green and that is usually during or just after the rainy season.

TIP – The highest chance of beautiful weather and the least amount of rain in northern Thailand is from November to January.
Best Time to Visit Central Thailand
Central Thailand is referred to as part of the land that lies between Cambodia and Myanmar. The best time to travel through central Thailand is from November to April. If you go later you have a greater chance of a heavy rain shower. Bangkok has been troubled by flooding during the rainy season in recent years.
Try to plan in advance where you want to go and in which season. Walking through flooded alleys with a backpack on your back is no fun; we speak from experience. The average temperature and rainfall in central Thailand are:

Best Time to Visit Southern Thailand
The south of Thailand has a more stable climate. This means that it is warm almost all year round. This is alternated by more rainfall than in the rest of Thailand. Rainfall starts in the south around April and continues until November.
The best time to travel through southern Thailand is from December to March. Especially December is recommended because nature is still beautifully green from the rainfall in the months before. The average temperature and rainfall in southern Thailand is as follows;

Different For Every Traveler
The best time to travel Thailand does not necessarily have to be the month in which the least rain falls. On a holiday or during your trip through Thailand you may prefer no rain, but the advantage of rain is that nature is at its best. Rice fields are greener, waterfalls are wider, and mountains and forests look more beautiful.
Especially in the north of Thailand, it is advisable to travel precisely after or during the rainy season. If you are more of the island hopping and partying type, you better go in the dry season.
