With its islands scattered across the Indian Ocean, Seychelles offers diverse and impressive diving opportunities. The “Inner Islands“ which are mostly Granitic Islands, rest on a shallow plateau with prolific marine life and excellent PADI diving facilities available to access a multitude of dive sites. |

The ‘Outer’ Islands to the south of the archipelago are all coralline or sand cays and mainly uninhabited, presenting the experienced diver with excellent opportunities to explore where few have gone before. Islands specialties Each island has its own special sites. All the northerly islands offer impressive granite reef locations where the sculptured rocks are covered with soft corals and sponges and fish life is prolific, due to the archipelago's isolation and also strict conservation rules. Diving in Seychelles is possible all year round but is governed by an island's position and the prevailing winds. In general the best conditions in both the Outer and Inner Islands are in the calm periods, April / May and October / November, when the water temperature can rise to 29ºC and visibility often over 30 meters on offshore sites. In December and January, the north-west winds blow but conditions remain much the same as in the calm periods. From May to September the winds are stronger and south-easterly. Visibility and temperature may drop during August and a wet suit of at least 4mm is necessary. The more southerly Outer Islands – some of which are in fact closer to mainland Africa than the Inner Islands – are near the cyclone belt and during December and January they can experience extremely rough conditions on occasion. A 4mm Shorty wetsuit is the minimum protection recommended for the outer islands. Islands with big drop-offs and walls often have marked thermo clines with temperatures ranging from 19 to 27ºC and a full suit is an advantage for most divers. Whale Sharks, those gentle giants of the ocean, are common visitors to Seychelles waters between October and April when it is often possible to swim with them. The Shark Research Institute runs a Whale Shark Monitoring Programs in conjunction with some local dive centers whereby clients can assist in ongoing research into the behavior of these spectacular creatures, swim and snorkel with the giants and participate in photo safaris and tagging exercises. |
