As the Seychelles islands are blessed with a year-long warm, tropical climate, it’s always a good time to visit, although different times of year may be better suited to your particular interests.
Two opposing trade winds generally govern the weather pattern: the north-westerly trades blow from October to March when wind speeds average from 8 to 12 knots; and the brisker south-easterly trades blow from May to September with winds of between 10 to 20 knots, bringing the cooler and windier conditions ideal for sailing.
The periods of calm between the trades produce fairly warm and wind-free conditions throughout April and also in October. Conditions for swimming, snorkelling and especially diving are superb during April/May and October/November when the water temperature sometimes reaches 29ºC and visibility is often 30 metres plus.
The ‘SUBIOS Underwater Festival’, showcases Seychelles’ extraordinary underwater world through a series of film shows, talks and competitions, while the 'Festival Kreol' (a week-long celebration of Creole heritage and traditions) is held in October of each year.
The Seychelles Sailing Cup, an international sailing event, is held in January and the International Fishing Competition in November. Further local fishing competitions are held throughout the year.
The table below summarises the best times to visit Seychelles for different types of activities.
