Please select your location:

Although the climate varies throughout Thailand, you can visit all year round. The best time to travel 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 favourable during the winter months, when diving and snorkelling 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.

Month-by-month guide to travelling in Thailand

Visiting Thailand in January

The weather is good throughout the country at this time of year. There is little chance of rain, while cooler temperatures in the north make conditions more comfortable and all the west coast beaches are likely to be bathed in sunshine.

Events & Festivals

  • Chinese New Year Festival (date varies): While this isn't a public holiday, it is celebrated across the country; particularly in Bangkok's Chinatown, which turns red and hosts exciting dragon parades, firecrackers and dancing in the streets.

What to do in Thailand: our highlights guide

To travel to Thailand and only see the beaches is to miss a magical and enthralling experience. This guide delves more deeply into what you can see and experience in this diverse country.

Thailand is another country with a distinct east versus west climate. The pick for us is either November, for the beautiful west coast beaches, or June, for beating the crowds and enjoying some of the country's cultural highlights with great weather.
