Diving in Koh Lanta
Koh Lanta offers all kinds of diving adventures for all skill levels. The beautiful, shallow reef and lagoon dives around Koh Lanta, Koh Haa and the Phi Phi Islands will mesmerize even seasoned divers.
Underwater pinnacles like Hin Daeng and Muang attract pelagics like manta rays and whale sharks, while sites around Lanta, Koh Haa, Koh Rok, and the Phi Phi Islands boast plunging walls and drop-offs covered in life.
There are also some exciting cave diving opportunities for experienced divers, such as those at Koh Haa, in particular, The Cathedral dive site, which is unmissable.
Many dive sites in this region are relatively shallow, though there are some deep diving possibilities, particularly at deeper open ocean sites.
Wreck diving is also possible at the Kled Gaeow shipwreck, which was a Royal Thai Navy vessel that was sunk purposely in 2014 to serve as a diving attraction. Plus, there’s the world-famous King Cruiser Wreck, which was a passenger ferry that sank in 1997 and is now home to a wealth of critters.
The best Months to dive in Koh Lanta
Koh Lanta boasts fantastic diving year-round, thanks to its welcoming tropical climate, with water temperatures averaging between 28-30C. November to April is the high season and the best time to dive, as the weather is usually dry and sunny, and sea conditions are the most favourable. In this season, the ocean is normally calm and visibility at its highest, although dive sites can be more crowded. Furthermore, this is the only time to dive at Hin Daeng and Hin Muang, due to favourable surface conditions.
From around May to the end of September, it’s the rainy season, although downpours are typically short and refreshing. Clear days still occur, and diving is still possible at sites that aren’t exposed to wind. Dive sites are way less crowded, and you’ll likely find deals on accommodation and diving in the low season.
In any season, the best time to dive is always just after the half moon period, when minimal tidal variation results in better visibility and next to zero current.
