Thailand: Weather & when to go: December

December Overview

For travellers looking for an end of the year getaway, December marks one of the most ideal times to visit Thailand. Rainfall is minimal across the country, temperatures are moderate and enjoyable, and sunshine can be found (almost) everywhere.

In the northern regions, Chiang Mai and Chiang Rai are in their winter months, where cool temperatures and low humidity are contrasted with sunny days. With temperatures hovering in the low to mid 20s, this is an ideal time for trekking experiences across the north. Further south in the country, Bangkok and the surrounding regions also experience ideal weather during December, which makes it a great time to visit.

For beach goers, the best of the year is coming back on the map again with ideal conditions spanning almost the entire region. Temperatures can reach as high as the low 30s and sunshine and blue skies are to be expected. Koh Kood, Koh Chang, Phuket, Krabi, Hua Hin and Cha Am are all ideal to visit during this time. Alternatively, the Gulf-destinations of Koh Samui and Koh Phangan are slowly moving out of their rainy season. While the occasional rain will pass through, sunny days slowly begin to offset the precipitation.
