Dive season would be during the dry monsoon, from April to November. The waters are generally clear, and the reefs are generally shallow, good for snorkelling. Both Perhentian islands are located about 24km off shore at the northern most part of Terrenganu. You'd have to take the bus to Kuala Besut, and from there, take the ferry to Perhentian. Dive Sites There are plenty of corals here, especially the colourful soft corals, and gorgonian sea fans.
Marine life is abundant.
Don't be surprised when you see dolphins and Pilot Whales in July and August, during the peak of the dry season. A fairly short boat ride away. Easy to moderate. Depending on currents. Lots of pelagics.
