The
Weather and Diving conditions in Thailand
This Thailand weather guide should
give you and indication on the underwater and surface conditions of the main
dive sites here in Thailand from Koh Tao to Phuket and Koh Chang to the Andaman
sea. The weather is hard to predict but the rain, surface conditions, underwater
conditions, waves and winds documented below have been based on many years of
experience of dive shop owners here in Thailand. You will find that Pattaya
boasts an all year round diving season and is great for training. For any
further weather condition reports please feel free to contact
