Seasons

Heavy rains in December and March affect currents and visibility at certain sites. Terengganu's Pulau Redang and Pulau Perhentian as well as Pulau Tioman in Pahang are
the sites most affected. The atoll of Layang Layang in Sabah is closed from November to March due to high waves and torrential rain. The Sabahan islands of Mabul and Tunku Abdul Rahman Park remain open all year round as they are sheltered by the Bornean land mass. Water temperature here rarely fails below 27 degrees Celsius. Visibility seldom drops beyond 30 metres.
