September weather and when to go
It can still be quite difficult to see the shells on the beaches off the south coast of Seychelles in September due to seaweed being blown in by the winds. However, there are plenty of other stunning beaches with fantastic snorkelling to visit at this time. The mercury generally sits at around 27 degrees making it the perfect temperature for lounging on the beach and wandering around the island in search of birdlife.
Manta rays still remain in the waters around the Maldives so you will be able to witness these magnificent creatures when snorkelling and perhaps even when out on boat excursions.
When not looking for rays there are some stunning species of coral to view from tree corals and sea fans to the peculiar bubble corals which look like fish eggs.
