While staying at Cousine Island, you will not only have the opportunity to explore the Inner Islands and their dive spots, but can also venture onwards for a Seychelles Outer Island Diving excursion. With steep wall drops, you can expect dramatic temperature changes in the water when enjoying a Seychelles Outer Island Diving excursion. It is as such recommended that you dive with a suit of minimum 4 mm thick and thicker. Although you will be able to dive from May –September, there are strong winds, with temperature drops and limited visibility. The best time for Seychelles Outer Island Diving will be before May and After September. December to January can also be characterized by strong turbulent conditions not suited for beginner divers. If you want to see whale sharks you should visit between October and April.
