Seychelles in September — Full Picture
September is a transitional late-dry-season month as the southeast winds gradually soften. It averages around 28°C/25°C with low-to-moderate rainfall and generally sunny days.
The easing wind means exposed coasts start to settle and the seaweed on southeast-facing beaches begins to lessen — conditions trend back toward the calm of the upcoming transition. North-coast beaches are still reliable, with more options opening up.
It's a quieter, better-value month than the July-August peak, with the European holiday crowds gone. Whale shark season continues, good for boat trips off Mahé.
A solid choice for travellers who want late-dry-season reliability with fewer crowds and softening winds, heading into the excellent October transition.
