Explore Surat Thani

In the Gulf of Thailand just south of Cambodia is the beautiful paradise region of Surat Thani, which is one of Thailand’s best diving hotspots. Consisting of 112 islands, all with seemingly infinite reefs and dramatic underwater topography, it’s no surprise that the region is often included in the world’s premier diving destinations. 

The most popular islands are the world-famous Koh Samui, Koh Tao and Koh Phangan, all of which are easily accessible by ferry from the mainland. Koh Ang Thong marine national park is also included in this area, which similarly boasts exceptional dive sites suitable for all skill levels. Whether you’re a diver or not, you’re bound to be engulfed by the islands’ white sandy beaches peppered with swaying palm trees, all surrounded by pristine waters overflowing with diverse marine life. Expect to see an array of species, from colorful hard and soft corals, macro critters like nudibranch and shrimp, tons of tropical reef fish, eels, stingrays and octopus, to bigger critters, like grouper, schools of barracuda, turtles, reef sharks, and even whale sharks.

The best Months to dive in Surat Thani

Diving is great all year round, with excellent visibility, averaging around 20–30 meters/66–98 feet. Weather is mostly hot and sunny year-round with water temperatures lingering around 28°C–30°C/82°F–86°F, though there are three distinguishable seasons involving hot, windy, and wet seasons. November is the rainy period, when overcast skies and storms occur, causing lesser visibility and choppier seas, but diving is still possible as some sites are sheltered from harsher conditions. May to September is the busiest season, when the weather and diving conditions are the most favourable.
