When to visit Thailand: Seasonal Overview

Spring in Thailand — November to March

This place receives the minimum rainfall, meaning it has the most favorable weather in all of Thailand.
Accompanied by favorable weather and an interesting beach-vibe, Koh Samet is where to head when in Thailand.

After the monsoon season, the sun returns to the country during these months. The weather in Thailand becomes dry and warm, making this the ideal season for some beach fun. There is little rain throughout the season (most of the rainfall happens in November). This is the high season, so there will be a lot of tourists around, especially during Christmas time. It is highly recommended that you book your tickets well in advance, as there will be a sharp rise due to the high season.

  • Avg. Temperature: 92 – 98° F / 33 – 39° C (in Bangkok)
  • Rainfall: 5 – 115 mm
  • Season: Spring
  • Highlights: These are the best months to visit Thailand for some premium beach fun. Head over to Krabi, Khao Lak, Ko Samui, and Phuket, where you can enjoy the warm waters, and the crisp breeze. If you travel towards the beginning or end of the season, you can escape the tourist crowd as well. There are a couple of festivals for you to enjoy during this season as well, including Loy Krathong, a local Thai festival celebrated in November; the Chinese New Year celebrated in January/February; and the one of a kind Chiang Mai flower festival in February.

Summer in Thailand — April to June

The weather in Thailand in these months is pleasant, but it slowly starts to heat up. The summer heat begins to rise, especially towards the end of April, and it will be quite hot inland. Towards the coastal regions, the ocean breeze will keep the climate in check. This is the shoulder season following a peak season, so you will be able to get good discounts, and enjoy the country bereft of tourists.

  • Avg. Temperature: 98 – 101° F / 37 – 38° C (in Bangkok)
  • Rainfall: 10 – 81 mm
  • Season: Summer
  • Highlights: This is the best time to visit Bangkok, Chiang Mai, Phuket, etc., as the crowds would have reduced, making the stay and tickets cheaper. The dry weather makes this the ideal time to explore Ayutthaya, the Khmer ruins, etc. as you will be able to walk without having to worry about the rains! If you’re in Thailand during this period, you can enjoy the beautiful New Year’s celebrations from the 13th to the 5th of April, also known as Songkran.

Monsoon in Thailand — July to August

Ko Samui, Thailand’s second largest island, lies in the Gulf of Thailand off the east coast of the Kra Isthmus.

This is the low season in Thailand, as the incessant rains drives tourists away. The summer temperatures wane, and the rainfall starts to increase. August experiences the heaviest rainfall of the year, especially in the Golden Triangle, and Chiang Mai. There will be lots of rainfall in the islands and the southern beaches as well. This is a low season, so you can enjoy good discounts on accommodation and travel prices.

  • Avg. Temperature: 95 – 96° F / 35 – 37° C (in Bangkok)
  • Rainfall: 71 – 87 mm
  • Season: Monsoon
  • Highlights: This is the best time to travel to Thailand, if you know which parts of the country to visit. The east coast beaches (like Koh Samui, Khanom) will be dry during this season, and enjoy a lot of sunshine, so you can head to these beaches, and enjoy a much cheaper vacation. You can even go diving at Koh Tao - and this is the high season for that! You can also explore the less known parts of Hua Hin, Cha Am, etc.

Fall in Thailand — September to October

Thailand promises endless adventure and exploration in a still relatively tourist-friendly atmosphere. It is hard to go wrong here — the food is excellent, the beaches are stunning and the people are very friendly.

September and October are still wet months, but in different parts of the country. Now, the monsoons shift to the east, making Koh - Samui and the south-east coast rather wet. Phuket, Krabi, etc. also experience a lot of rainfall during this period. This season is much better in North and the gulf coast - so if you want to head to Chiang Mai, now is the time!

  • Avg. Temperature: 93 – 94° F / 34 – 34° C (in Bangkok)
  • Rainfall: 179 – 247 mm
  • Season: Spring
  • Highlights: This is when to visit Thailand for vegetarians - as the 9 day long Vegetarian Festival in Phuket takes place in October! This is also a wonderful time to visit Khao Sok National Park, where there will be a lot of rain, but the entire area will look lush and green, giving you a splendid view. Wildlife enthusiasts will have a greater chance of spotting wildlife during this period as well!

Thailand is a year-long holiday destination, hence best time to visit Thailand depends on what you’re looking for in your journey. No matter when you plan your trip to Thailand, this beautiful country promises unforgettable experiences, from vibrant festivals to serene beaches and lush jungles.
