September continues the trend of trade winds; humidity is lower and rainfall is typically moderate. This month sees fewer tourists and good availability at hotels. Some dive operators prefer shoulder months for best underwater visibility, though September can still be fine.

Where to Go in Seychelles in September
Mahé - Victoria, Beau Vallon and West Coast
September often feels like a continuation of the trade-wind season with warm sunny days and cooler, windy nights; it can be one of the sunniest months on the west coast. Anse Intendance and other surf beaches pick up swell, attracting bodyboarders and surfers while calm bays remain excellent for swimming. This shoulder-season timing offers steady weather for hiking Morne Blanc and coastal walks; bring sunscreen, windproof outerwear and secure footwear for sandy trails.
Mahé Highlands - Morne Seychellois and upland trails
September brings steady trade winds and warming days while the highlands remain cooler than coastal areas; early fall-like conditions improve the comfort of full-day ridge walks. Waterfalls may be lower than during the wet months but rainforest streams still flow, and the undergrowth shows fresh new leaves after the drier winter months. Plan careful sun protection for exposed ridgelines and a light rain jacket for unexpected showers.
Praslin & La Digue - Inner granitic islands and beaches
September remains one of the sunniest months with steady trades keeping humidity in check and offering blue-sky mornings ideal for full-day boat trips to Curieuse and Félicité. Anse Lazio remains a magnet for early visitors and photographers, and tide pools around La Digue are excellent for exploring at low tide. This is a good month for long treks and uncrowded beach time; sun protection and water shoes are smart packing choices.
Outer Islands & Atolls - Aldabra, Farquhar, Alphonse and more remote coralline islands
September often offers very stable weather around the coralline atolls with good visibility for diving in sheltered lagoons and steady winds for reliable boat travel. Migratory seabirds can be active and turtle-nesting observations occur at different times depending on species; local guides and research stations will advise on best viewing practices. Bring lightweight long-sleeves for sun protection and a decent portable water filter for remote stays.
