Dive Site Overview
Twins provides a balanced environment for both dive training and recreational exploration, appealing to a wide range of certifications. Its topography features three main pinnacles running east to west, with two large boulder groups abundant in coral and further complemented by deeper rocks towards the west.
Diver experience levels are easily accommodated, as depths range from 6 m (20 ft) on the eastern side to a maximum depth of 18 m (59 ft) at the deeper western pinnacle. Being shielded by Koh Nangyuan island, the site consistently presents calm waters, fostering a rich environment where marine life thrives. This protection is a key factor in its suitability for training.
Adjacent to Twins, Buoyancy World serves as a dedicated training area. It incorporates structures explicitly designed to help divers refine buoyancy control, improve finning techniques, and practice precise underwater movements in a controlled setting.
This setup proves ideal for Open Water, Advanced Adventure, and Rescue Diver training, alongside providing enjoyable fun dives for certified individuals seeking relaxed exploration.

During these months, average air temperatures hover around 28.4°C (83°F) in March and climb to 29.5°C (85°F) in April, with minimal rainfall averaging 0.9 mm and 1.5 mm respectively. These conditions typically ensure good visibility and gentler currents, which varies depending on seasonal conditions. While the site generally provides shelter from wind and waves due to Koh Nangyuan's proximity, the transitional periods outside of these peak months still provide good diving, albeit with potentially higher wave heights or increased rainfall, particularly from June through November.
