Bangkok, Phuket & Krabi
Best months: November-March
For central and southern Thailand such as Bangkok, Pattaya, Phuket, and Krabi, November to March brings in the cool and dry season, and it even sometimes extends to April. It’s ideal for exploring beaches and cities with temperatures from around 29°C-34°C.
And if you’re looking for things to do in Bangkok, we’ve got you sorted with 50 different ideas to choose from.

It goes without saying, but you’d want to avoid going to beach destinations like Phuket and Krabi during the rainy season, lest you end up having to spend your vacation indoors. Additionally, monsoon season can result in choppy seas. Not to mention, potential flooding can also happen in some areas.
Chiang Mai, Chiang Rai & Pai
Best months: November-February
Northern Thailand is one of the coldest places near Singapore, especially from November to February. Temperatures in the day range from around 23°C-28°C, and nights can drop to as low as 10°C – so don’t forget to pack a jacket if you’re going there.
Worst months: February-April
However, keep in mind that the season right after that is the burning season, where farmers in Northern Thailand and Laos use a traditional practice to cut down and burn their remaining vegetation from the previous harvest.
