Planning a trip to Thailand?

Thailand weather by month

Having experienced different seasons across the country, I can tell you that Thailand’s weather varies greatly. The country’s long shape means it’s not always as hot as you’d expect—I’ve experienced a surprising chill in the cool mountains of Chiang Mai, even while the rest of Thailand was sweltering.

And the rainy season doesn’t hit everywhere at the same time, which is something to keep in mind when choosing southern islands.

Whether you're after perfect weather or fewer crowds, the right timing can make all the difference.

Let’s break it down so you can plan your ideal trip!

Best Time to Visit Thailand

The best time to visit Thailand is generally between November and February, the cool season, when you’ll find cooler temperatures, less rain, and ideal conditions for sightseeing and outdoor activities.

However, be aware that this is also the peak season, so expect higher prices and larger crowds.
