There are three main types of dive sites:
* On coral reefs inside the atolls - These are 'house reefs' around resort islands; or steep sided underwater hills called 'thilas' and 'giris', which rise from the bottom of lagoons. Reefs inside Maldivian atolls are notable for the huge number and variety of tropical fish. |

* A channel between islands on the outer edges of an atoll is called a 'kandu', and funnels water between the lagoon and the open sea. Kandus are ideal for drift dives, and often attract large marine animals that come to feed on the plankton-rich waters flowing out of the lagoons. * A reef on the outer edge of an atoll is a 'maa kandu', and usually has less current, greater depth and excellent visibility; whale sharks, mantas and turtles often cruise the outer reef slopes. Though the hard coral in the Maldives was badly damaged by 'coral bleaching' associated with the 1998 El Niño event, there are still impressive growths of soft coral, and the hard corals are recovering. The amazing fish life of the Maldives is as prolific as ever - over three-quarters of the world's reef species are found here. It's worth getting one of the marine field guides that will help you to identify the many types. To help plan your trip, and to get some inspiration, check out one of the published dive guides to the Maldives. "Dive Maldives" by Tim Godfrey is recommended, and widely available in the country or from the internet. | |

The Maldives year has two main seasons - the north-east monsoon, from December to April, and the south-west monsoon, from May to November, which is the wet season. The ocean currents flowing through the Maldives follow the direction of the monsoon winds, and have a big effect on diving conditions.

Generally, January to April are excellent months for diving, with clear weather, low humidity and visibility averaging about 120 feet. In April, during the transition to the south-west monsoon a plankton bloom will often occur on the eastern side of the atolls - this attracts mantas and whale sharks to feed in the channels (though it may reduce visibility down to around 70 feet).
Winds strengthen during May, and the months from June to September have monsoon rains and strong winds. November sees the transition to the north-east monsoon, with winds moderating and shifting. Plankton blooms can occur, attracting mantas and other big pelagic species to channels on the west side of the atolls. The temperatures are very consistent all year round, with daily maximums averaging about 30-32°C (85-89°F). Water temperatures range from 26-28°C (78-82°F). | |

It's best to bring your own mask, snorkel and fins - you'll always have them handy for spontaneous snorkelling and you'll know they fit you and suit your needs. It's a good idea to bring a 3mm wetsuit too. Most dive centres have some wetsuits to rent, but they may not be available in exactly your size. Regulator, BCDs, and dive computers are available at all resorts, and on safari boats by prior arrangement. For drift dives, a safety sausage or 'parachute' is an essential piece of safety equipment.
