Traveller notes on Perhentian Islands in December
Other months in Perhentian Islands
Perhentian Islands' forum is candid that March is a coin flip — some years it's calm, clear-water conditions perfect for the beach, others it's still catching the tail end of the monsoon with rough, murky seas. Regulars say the north-east monsoon usually eases by mid-March but doesn't stick to a schedule, so it's worth playing it by ear rather than booking too far ahead.

Islands shut for the monsoon
1 Nov – 28 Feb · usuallyAlmost every resort closes and boat services stop for the season, which is a state-wide pattern across the Terengganu islands rather than a decision by any one operator. Plan around it, not through it. Source ↗
