Time your visit with the Seychelles' seasons
The Seychelles have a fabulous climate which is predominantly rules by two trade winds which hit the island each year. The northwest trade wind blows from November to March and the southeast wind from May to September. The best time to visit the islands is between April and May, or October and November - during the calmer period between the two trade winds.
Being close to the equator, the temperature in the Seychelles is roughly 30°C (86°F) year-round, with a mixture tropical showers, sun-filled days and sea breezes which help to alleviate the humidity. As the islands are so far away from any other land mass, it's very hard to predict the weather or rely on online forecasts.
The months of the year with best visibility for snorkelling and diving are April and October, with whale sharks most frequently seen between September to November, and turtle hatchling season from January to March.
