Phuket diving weather in January

January is usually a great month for diving Phuket and Khao Lak or anywhere else along Thailand’s Andaman sea west coast.

The weather should get better and better towards the latter part of the month.

It’s a dry month with a slight breeze from the south west.

Seas should be flat, the temperature is hot and dry with hardly a cloud in the sky.

Tourist areas are busy and dive boats are full.
