Traveling to Thailand in winter is ideal as the monsoon rain moves out and drier, pleasant weather returns. But better weather certainly draws bigger crowds. The busy season spins up for Thailand in winter and continues until the heat becomes nearly unbearable in late spring.

The Busy Season in Thailand

As with most countries that experience monsoon seasons, improving weather lures more and more travelers to enjoy sunny days.

Thailand can certainly still be enjoyed during the monsoon season (May to October), but the weather may be less predictable for taking advantage of the many outdoor activities.

Although Thailand is usually so busy with tourism that trends are becoming more blurred year after year, the high season begins to wind up in November. Popular destinations get busier as winter in Thailand proceeds. Cold weather in Western countries brings more people searching for sun in the beautiful Thai islands.

Christmas is a busy time in Thailand, but even more travelers turn up in January and February after holiday celebrations at home are finished.

The Weather for Thailand in Winter

Traveling to Thailand in winter is a great idea for enjoying the best weather of the year for the region. With rain from the monsoon season slowing around November, the country really dries out by January and February.

Temperatures climb steadily until reaching three-shower-a-day levels in April, the hottest month.

December, January, and February are typically the months with the best weather in Thailand.

Is Winter in Thailand Cold?

Not really. Nighttime temperatures in places such as Pai in the mountains of Northern Thailand can feel a bit chilly after hot afternoons, but temperatures never really dip below the mid 60s Fahrenheit. A light cover-up or thin jacket will suffice; you’ll want one anyway for the freezing temperatures on buses due to the drivers’ overuse of air conditioning!

Haze and Smoke in Thailand

Each year slash-and-burn agricultural practices start fires that burn out of control, primarily in Northern Thailand. The haze and smoke from these fires linger, causing respiratory issues and even occasionally prompting the shutdown of Chiang Mai’s international airport.

The haze really peaks in March and April, however, there’s a chance that some fires will already be burning in February or sooner. Travelers with asthma or other respiratory problems should check the particulate matter levels for Northern Thailand before traveling there.

Winter Festivals in Thailand

Most of Thailand’s biggest festivals, aside from Chinese New Year, tend to be in either spring or fall rather than winter. See a list of other winter festivals in Asia.

  • The King’s Birthday: December 5 is the King of Thailand’s Birthday, an event celebrated with pageantry, a candlelight vigil, and a rare motorcade appearance by the king himself when his health is good. Bangkok is the epicenter of the celebration.
  • Chinese New Year: Chinese New Year is observed in Thailand with lion dances, parades, stage shows, and lots of fireworks. The holiday can be a very busy time to travel in Bangkok and Asia in general. Prices for flights and accommodation sometimes spike as demand increases. Chinese New Year, usually in January or February, is based on a lunisolar calendar, so dates change each year.

    Christmas in Thailand

    Christmas is observed in big cities around Thailand, particularly Bangkok and Chiang Mai which large expat communities call home. The many malls in Bangkok’s Sukhumvit area will have Christmas trees and decorations in place, although not nearly as early as Western countries do. You may even see a Thai Santa Claus running around!

    The Christmas Full Moon Party at Haad Rin on the island of Koh Phangan is one of the largest of the year. More than 30,000 travelers will meet on the beach to party for Christmas and New Year’s Eve.
