Thailand is well-known for its scuba diving, in which hot, calm waters and plenty of amazing marine life result in spectacular dives. Thailand's scuba diving is also quite cheap compared to diving in other areas. To get the best out of diving in Thailand, then you need to understand when and where to go. Not all Thailand's scuba dive sites are accessible throughout the year, so it is good to do a little bit of planning. Here is a guide that can help you. 


The Similan Islands are known to be one of the best dive destinations. They are a group of uninhabited islands in the Andaman Sea, just off the western Thai shore. The Similans are often visited by live-aboard ships from Phuket and Khao Lak, where Australians eat, sleep and dive on the ship for several days. Normally the live-aboard lasts four days and four nights also lets the members get 14 dives. Be certain to ask your operator concerning the newness of their scuba gear as well as their staff credentials. The Similan Islands are just available to divers from October to May every year. The monsoon season arrives from June to September and leaves the seas too dangerous for safe diving. More adventure, see now at diving phuket.


There is a collection of dive sites further south in the Andaman Sea and accessible from Phuket, Krabi, Koh Lanta and Koh Phi Phi. They are typically seen on day trips from these destinations, but there a couple of liveaboards who see them. Koh Lanta specifically is a lovely Thai island which is not quite as active or pricey as Koh Phi Phi. Hin Daeng and Koh Ha will are open from October to May only. Koh Bida and Phi Phi possess a couple of flora which are available all year round if you are touring Koh Phi Phi. 


Koh Tao is a small island on the other, eastern shore of Thailand, above Koh Phangan. Koh Tao is a four-hour ferry ride from Surat Thani on the mainland. Koh Tao is a famous island for divers and lone relaxing, though popular, Koh Tao remains quite uncrowded. If you want to learn to dive but don't wish to devote to performing a live-aboard, Koh Tao is a great place to find out and enjoy the party landscape also. Koh Tao's monsoon season lasts from September to December. 


The best times of the year to dive in Thailand are October to May for the Similan Islands and Koh Ha or Hin Daeng and January to September for Koh Tao. When planning for your Thailand diving trip, think of what time of year you can go and then decide if you would like to do a live-aboard excursion or day trips and go back to the hotel every day. Ask the dive operators the available excursions and dive packages that are offered. The dive operator may also give you the very best advice of the way to get from where you live to your dive destination. Visit us at
