When is the Best Time to Visit Thailand?

Thailand is a great year-round destination, but the best weather is usually between November and April. The climate varies between the east and the west coast. September brings the heaviest rainfall on the west coast, while the east coast gets its highest rainfall in November. Summer is from April to June, and the rainy season is from July to October in most of Thailand.

  • Best Time to Visit Thailand for Good Weather: Being a tropical country, Thailand is warm through the year, with winters having average highs of 26-28ºC, and summers, 32-40ºC. The north and west have their rainy season from June to October, and the east from November to March. The best weather is usually found in December, January, and February.
  • Best Time to Book Hotels for Thailand: The Best Hotels in Thailand get booked early – especially for the Chinese New Year, Kin Jay (vegetarian) festival, and the months of December and January. Try to reserve rooms at least 2-3 months in advance for peak season, and about 1-2 months in advance for the low and shoulder seasons.
  • Best Time for Surfing: The best time for surfing in Thailand depends on whether one is planning to go to the east coast or the west. Surfing is especially great for beginners and long boarders as the waves are smaller (about 3-10 feet). April to October is a great time to surf on the west coast, and October to December on the east coast. However, many islands have very shallow coastal reef in places, which can be dangerous below mid-tide.
  • Best Time for Snorkeling and Swimming: Great swimming and snorkeling is possible year-round in Thailand, except on days when there are thunderstorms during the rainy season. November to April is probably the best time, especially around the islands in the Andaman sea.
  • Best Time for Hiking: The cooler months of October to February are preferable for Thailand’s incredible hiking/trekking. Though hiking can be done year round, summers can get very hot here, so pack plenty of water, sunscreen, and mosquito repellent. Starting the hike early in the morning is advisable to beat the afternoon heat.
  • Best Time for Whale and Dolphin Watching: The Gulf of Thailand on the east coast is where whales mostly reside. Bryde’s whales come close to Bangkok’s shores between September and December to feed on the abundant anchovies. Irrawaddy (river) dolphins with rounded foreheads can also be seen splashing in the Chao Phraya river at this time.
  • Best Time for Fishing: One can fish in Thailand through the year, with different fish biting at different times around the large coastline and off the islands. Fishing in the rainy season is ideal. Thailand is especially known for its freshwater fish. Apart from the common species of fish, native species such as Giant Mekong Catfish, Barramundi, Siamese Carp, and Giant Snakehead are very popular. Fishing spots range from fishing parks to special resorts, ponds, lakes, dams, and rivers.
  • Best Time for Discounts: Booking early and catching mid-week flights would get the best discounts. Usually, the best rates for flights and hotels are during the rainy season. March to May, September, and October usually find great rates. The annual grand sales in the mega malls run from mid-June to mid-August, which is actually a busy travel season.
  • Best Time for Avoiding Crowds: The quietest months for tourists are April, May, September, and October. Late August is also fairly quiet except for European travelers.
  • Best Time for a Destination Wedding: With its tropical beaches and sunny weather, Thailand is a great year-round wedding destination, except during the peak rainy season. Rains tend to fall in short bursts that quickly dry up in the beginning and the end of the monsoon. November to February is the best (and safest) time to get married on the west coast, and June to September on the east coast.
  • Best Time for Inter-Island Cruises: September to December is the best times to spot whales off the sides of your ship, but November to January is also the most expensive time to visit. The start and end of the rainy season are the best time to get deals on cruises.
  • Best Time for Buying Airline Tickets: Airline ticket prices depend on the season, festivals, events, and trade fairs. Generally, booking one to three months in advance offers the best rates, with six weeks prior giving the optimum deals. Exceptions are when booking for Chinese New Year and December-January. For these periods, it’s best to book as early as possible.

When To Visit Thailand


The Best Time to Visit Bangkok

Bangkok is a great metropolis worth visiting year-round, except in September and October, when the rains are heaviest. However, November to February is a great time to visit as the rains have receded and the weather is cooler (average max temperature ranges between 27°C to 29°C). Visiting in the rainy season is a good idea to get excellent deals on hotel rooms and enjoying the many indoor activities that the city has to offer, in case it is pouring outside. The annual “Amazing Grand Sale” is held from mid-June to mid-August, and shoppers can find incredible deals, including discounts up to 80%, on clothes, electronics, jewelry, and more. April to June are the city’s hottest months, and July and August are the wettest; both periods seeing thinner crowds and lower airfare and accommodation rates. The high season also coincides with New Year’s Day as well as the Chinese New Year. The 9-day Kin Jay (Vegetarian) festival in September/October is also very popular, when all of Thailand observes the Chinese cleansing festival, and several stalls and restaurants put up yellow flags to announce their participation by serving only vegan food.

The Best Time to Visit Phuket

The best time to visit Phuket is from November to April, when the weather is cool and ideal for beach and water activities. Phuket’s daily highs range from the 31°C to 34°C year round, warmer in the summer and cooler in the winter, but only slightly. May through October is the monsoon season, with hotels offering excellent rates, though the water can be dangerous at times when the weather is stormy, especially on the west coast. The east coast is relatively calmer through the year. December through March is high season, with maximum occupancy and rates. The low season falls from May through October, when humidity is really high, leading to low room rates. September to December is the best time to catch whales in the Gulf of Thailand, off Phuket’s east coast.

Best Time to Visit Chiang Mai

The peak tourist season in Chiang Mai is from December to January, so the months before and after, i.e. November and February, are the best months to visit the hill station to enjoy the weather and avoid the crowds. The cool and pleasant weather is complemented by light breezes during these four months, which is perfect for all kinds of outdoor activities. Temperatures range between 10°C and 30°C during winter. Chiang Mai has three seasons: summer (March to May), monsoon (June to October), and winter (November to February). Temperatures can go up to 40°C in the summer, and it gets very hot and humid. The monsoon months are slightly cooler, and the short bursts of heavy rains can give a cool respite. However, the thin crowds and the freshly washed lush green vegetation make it a pleasant time to visit. Chiang Mai comes alive during Thai festivals, and especially during the Flower Festival (first weekend in February), Songkran (mid-April), and Loi Krathong (usually in November).

Best Time to Visit Krabi

Krabi is located in southern Thailand, and offers exceptional natural beauty—national parks, virgin beaches, islands that can only be reached by boat, and relatively less commercial tourism. November to March is the best time to visit Krabi, with the monsoon just over and the summer about to set in. Temperatures range between 22°C to 32°C. Unlike the rest of Thailand, Krabi has a more tropical climate which can be described as dry (December to April) or rainy (May to November), with the highest rainfall occurring in September and October. Compared to most places in Thailand, summers are not that hot in Krabi, with the highest average temperature seldom crossing 32°C. Traveling in the rainy season can either be a dampener with heavy showers, or one can get lucky and have a sunny day with cheap prices and an entire island to themselves. November to April is also the ideal time for water-sports like wind-surfing, kite surfing, and wake-boarding, while scuba diving, snorkeling, and swimming can be enjoyed through the year, whenever the waters are calm.

Thailand Travel Seasons

  • High Season (November-April): Late November to early April is Thailand’s high season, especially around the Christmas, New Year, and Chinese New Year holidays. Flights and hotels are usually the most expensive then. Hotels usually have stricter stay, deposit, and cancellation policies around these holidays. It is best to plan and book early for travel in the peak season.
  • Shoulder Season (April-May and September-October): The two shoulder season periods are an excellent time to visit Thailand, when the monsoon is either just setting in or leaving, and the temperature is not very hot. Prices are lower, and beaches and attractions are less crowded. The occasional short or heavy shower will cool the temperature, though the water will be off-limits if there is a storm. It’s also a great time to go surfing or diving on the west coast of Thailand.
  • Low Season (May to September): Summer in Thailand is very hot and humid (temperatures can go up to 45°C), but it’s still a great time to enjoy the huge selection of indoor activities the country has to offer. During the rainy season, it can rain virtually every day, and afternoons can get almost intolerable in the summer. The stormy weather can also hamper diving, surfing, and other water activities. However, it’s very cheap to travel during this time, bookings can be done last minute, and one can even negotiate prices at the hotel upon arrival. The empty beaches and public attractions allow tourists to have a more leisurely vacation.

Thailand Weather by Month

Temperatures in tropical Thailand are warm all year long. The rainy season varies in different parts of Thailand, with the rare big storm seen on the west coast in August-September. The north eastern rainy season is from November to April, and the south western, from May to October. Brief and light showers occur regularly everywhere. Southern Thailand gets the most rain, northernmost point gets the lowest, and central Thailand, including Bangkok, is usually the hottest.

  • Thailand Weather in January: January is one of the very few cool months in Thailand, with temperatures hovering between the low 20s (ºC) and low 30s (ºC) in most places, and Chiang Mai being the coldest with a minimum temperature of 10-15ºC. Rain is scarce. This is peak holiday season in the country, and everything is full. A light sweater or jacket is advisable in the evenings. (Average water temperature 28ºC.)
  • Thailand Weather in February: The average temperatures in February are similar to January, around 22-32ºC. The chances of rain in the north increase while they recede in the south. The weather is excellent in southeast and southwest Thailand, with lots of sunshine and temperatures in the mid-20s. (Average water temperature 28ºC.)
  • Thailand Weather in March: March is the precursor to summer in Thailand, and temperatures start rising rapidly. It is also the beginning of shoulder season, especially on the islands, so crowds start thinning out. It’s very dry, and a great time to scuba dive off the west coast. (Average temperature 26-31ºC, though it can go up to 35ºC in the daytime. Average water temperature 29ºC.)
  • Thailand Weather in April: Hot and oppressive due to the high humidity. The south and east coast could be a little cooler, and occasional showers on the west coast as monsoon approaches. (Average temperature 29-34ºC, but can go over 35ºC in several places. Average water temperature 30ºC.)
  • Thailand Weather in May: May can be slightly cooler, but just as oppressive, and strong bursts of rain increase humidity drastically. Crowds are thin despite plenty of bright, sunny days. Northern and eastern Thailand are almost dry. (Average temperature 28-34ºC, but can go over 35ºC in several places. Average water temperature 30ºC.)
  • Thailand Weather in June: The monsoon covers almost the entire country, with a high chance of rain on the west coast. Weather is otherwise similar to May’s. (Average temperature 28-34ºC, but can go over 34ºC in several places. Average water temperature 30ºC.)
  • Thailand Weather in July: Rains are heavier and the temperature dips slightly, with the west coast getting more showers than the east. (Average temperature 33ºC. Average water temperature 29ºC.)
  • Thailand Weather in August: North and west Thailand get their highest rainfall, while the east coast is relatively sunny and dry in August. Humidity levels are fairly high. (Average temperature 32ºC. Average water temperature 29ºC.)
  • Thailand Weather in September: Beach conditions are poor throughout the country due to heavy rains and stormy seas. Unsurprisingly, crowds are thin, and accommodations can be rented at a steal. (Average temperature 32ºC. Average water temperature 29ºC.)
  • Thailand Weather in October: Rains and humidity levels start decreasing, and northern Thailand starts feeling the cool impact of the onset of winter. The south is still relatively hot and humid. (Average temperature 30ºC. Average water temperature 29ºC.)
  • Thailand Weather in November: Eastern islands like Koh Samui and Koh Pha Ngan have their wettest month, but the rest of the country is pretty much dry and pleasant. This is also the start of the peak travel season in Thailand. (Average temperature 30ºC. Average water temperature 29ºC.)
  • Thailand Weather in December: December is one of the best months to visit Thailand, as rains are minimum and days are sunny and pleasant. The southeast experiences rainfall, but the west coast is ideal in this period. A light sweater might be advisable in the evenings in the north. (Average temperature 30ºC. Average water temperature 28ºC.)

4 Questions and Comments

If you have a hotel or travel question sign up for my newsletter and I'll give you directions on sending me questions.
  1. Thailand in October

    Hi would you not recommend Thailand in the first 2 weeks in October? I wanted to take my Hubby for his 50th birthday but not sure about the weather? Bangkok followed by Krabi. If not where would you recommend for that time of year?

    1. Santorini Dave The Hotel Expert

      You can have a great visit any time of year – certainly in Bangkok but even the beaches can get a nice string of pleasant weather in the rainy season. But would I recommend going in October? Not really. A better choice? Bali has good weather and cheap prices in October.

  2. Thailand for Family – When To Go?

    We are a family of 5 with kids aged 5, 6, and 10. When would you say is the best time for a family vacation in Thailand? We want to swim, spend time at the pool, and do a little sightseeing (but not too much).

    1. Santorini Dave The Hotel Expert

      January and February are the absolute best months but anytime between December and March is great. April and early May are good too as long as you can stand the heat. June through September are still fine but weather is better on east coast than west coast.
