Diving Seasons & Conditions in Seychelles
A paradise for divers, open to exploration all year round.
When to Dive
Diving in Seychelles is possible all year round but is governed by an island's position and the prevailing winds. The ideal months are March / April and October / November when the water temperature is perfect and visibility is good.The Islands
These islands are a beautiful scenery for sea lovers, they offer impressive granite cliffs, rock carved by the sea covered with coral, and sponges, the marine fauna is also alive and abundant thanks to the strict environmental protection measures in which we are very active.01 Marine Life
The marine flora and fauna of the neighboring islands reveal an abundance of fish also on the cliffs near the coast : butterfly fish, angel fish, emperors, soldier fish, squirrel fish, glass fish and parrot fish are just some of the species that can be admired in seabed. Among the most incredible species are the whale sharks that go around the islands from June to December, particularly September and October.

Peak sightings September – October
02 Dive Conditions
Generally speaking, the best conditions in both the Outer and Inner Islands are during the calm periods of April / May and October / November, when the water temperature can rise to 29°C and visibility often exceeds 30 metres on offshore sites. In December and January, the north-west winds blow but conditions remain much the same as during the calm periods. From May to September the winds are stronger and south-easterly. Visibility and temperature may drop during August and a wetsuit of at least 4mm is recommended.
03 Outer Islands
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 3mm shorty wetsuit is the minimum protection recommended for the Outer Islands. Islands with big drop-offs and walls often have marked thermoclines with temperatures ranging from 19 to 27°C, and a full suit is an advantage for most divers.
