Seychelles in May: Weather, Crowds & What to Expect

Mahé - Victoria, Beau Vallon and West Coast

The southeast trade winds start to build through May and the west coast becomes pleasantly breezy and drier, with highs around 27-29°C. Beau Vallon and northwestern bays are sheltered from the winds, making them prime for swimming, paddleboarding and sunset strolls while the east coast feels windier and rougher. Hotel rates typically ease off after the peak season; bring a light windbreaker for breezy evenings and a larger reef mask for clearer water along the sheltered west coast.

Mahé Highlands - Morne Seychellois and upland trails

A steady breeze and drier conditions arrive in May, reducing cloud at the summits and making long ridge hikes much more comfortable; daytime temperatures on the high plateaus often sit in the low to mid-20s°C. Birdwatching improves as songbirds are active in clearer weather, and trails like the Crayfish route dry out enough for less-slippery trekking. Pack layers for morning chill, waterproofs for unpredictable squalls and a telephoto lens for endemic species sightings.

Praslin & La Digue - Inner granitic islands and beaches

May’s arrival of the southeast trades cools the islands slightly and clears the air; days feel breezier on windward slopes while sheltered bays stay warm and inviting. Beach swimming at Anse Georgette and Petite Anse are particularly enjoyable as surface conditions calm and cross-shore breeze keeps insects down. This is a quieter shoulder season - accommodations may be easier to find and bike hire on La Digue is convenient; pack wind-resistant clothing for cooler evenings.

Outer Islands & Atolls - Aldabra, Farquhar, Alphonse and more remote coralline islands

May’s established southeast trades begin to alter sea state around the outer islands: windward faces can become exposed but many atolls have sheltered lagoons that remain pleasant for snorkeling and fishing. Cooler sea-surface conditions on exposed reefs can improve visibility in protected spots, though cross-lagoon boat transfers may feel bumpy. Travelers should prioritize sheltered anchorage options and bring protective clothing, reef shoes and a reliable dry bag for gear.
