We are asked this kind of question regularly …. “When is the best time to come to dive in Thailand?” or “Is July a good time to dive in Phuket?”. We get a lot of enquiries for the Similan Islands in the summer, when they are closed, and people wanting to dive Komodo in January which is the rainy season there, so it’s best to have a reference on the website, hopefully it will help people to plan a diving trip in Thailand or Indonesia. If you are a diver, find out first where the best diving is to be found at what time of year
Thailand Diving Season (Phuket / Similan Islands)
There are actually 2 main seasons in Thailand. We are located in Phuket, on the west coast, with the Andaman Sea as our playground. The Similan islands is the main liveaboard destination, though there are also liveaboards to Myanmar and also day trips and overnight trips around dive sites near Phuket and Phi Phi. The season for diving the Similan islands is November to April. The Similan islands national park is officially open from October 15th to May 15th. Some boats run trips only November to April, but there are liveaboards in late October and early May also. For local day trips around Phuket and Phi Phi, you can come year round. Generally the weather is better in the high season, but from May to October you get a lot of good weather mixed in with the wet days, and hotel prices are very low, and there are plenty of wet season diving options from Phuket.
Indonesia Diving Seasons
Indonesia is a big country so the weather is not the same everywhere. We offer liveaboard trips in two main areas, and they have different seasons. Komodo – there are trips from March to December with the best time being June to October – just the opposite of the Similan islands in Thailand. A Komodo trip can be combined with some relaxing in Bali, as the liveaboards depart either from Bali, or from Labuan Bajo, reached by a short domestic flight from Bali. And for Raja Ampat it’s the other way around – best time is November to April.
