The best time to visit the Seychelles is during the dry season between May and September when the tropical high temperatures are cooled by sea breezes. The seasonal transition months of April and October can also be good months to visit.
The Seychelles remain a year-round destination despite rain showers, which generally fall as sudden, heavy downpours that quickly clear leaving sunny, blue skies.
The Seychelles experiences a tropical climate governed by the trade winds with an annual temperature range between a high of 30°C (86°F) and a low of 23°C (73°F), with humidity around 80 per cent.
The pre-southeast monsoon period of April is usually calm and virtually windless with an average temperature of 28°C (82°F) peaking at 31°C (88°F) with a low of 25°C (75°F).
From May to October, the southeast trades bring cooler, drier weather that is also quite windy. From June, the average daily temperature drops to 26°C (79°F) peaking at 28°C (82°F) with a low of 23°C (73°F). July and August are the driest months.
The pre-northwest monsoon period of November is usually the onset of the rainy season with light winds and an average temperature of 27°C (80°F) peaking at 29°C (84°F) with a low of 23°C (73°F).
The hottest time of year is between November and April with the arrival of the northwest trades, which bring wet and warm airstreams and an average high around 30°C (86°F) with a low of 24°C (75°F). March and April are the hottest months.
The rainy season lasts from November to March, and while downpours can be heavy, they rarely last long. The wettest months are December and January.
High season: Typically, the peak season runs from mid-December to mid-January, the Easter holidays and from July to August.
Tip: Plan your trip around what you want to do. Hiking, surfing and windsurfing are best at the start and end of the trade winds, usually around April and October; while diving, swimming and snorkelling are best during April/May and October/November when the water temperature averages 28°C (82°F) and visibility is often more than 30m.
Bird watching is best in April during the breeding season, between May and September for the nesting of sooty terns, and in October during migration. Game fishing is best between October and April.
