September
#1 of 12 months
Best match
Transition to calm — trades ease, both coasts begin recovering, and the second sweet spot approaches.
- ↑September marks the beginning of the second transitional period: the southeast trades ease, both coasts begin to calm, and by mid-September the west-facing beaches start to recover their sheltered character; visiting in late September catches this transition and accesses both island coasts for the first time since April
- ↑Hawksbill turtle nesting season continues into September: both nesting and hatching can be observed in the same period on Cousin Island, and September is specifically the peak of hatchling emergence — watching dozens of hatchlings navigate from nest to sea on a moonlit beach is among the most moving wildlife moments in the Indian Ocean
June
#2 of 12 months
Best match
Southeast trade winds established — east coasts calm, west coasts rougher, and prices at their lowest.
- ↑The southeast trades establish fully in June, and the east-facing beaches — Anse Intendance and Anse Takamaka on Mahé, Grand Anse on Praslin — are now calm and sheltered; these beaches, inaccessible and rough in January–March, are at their finest from June through September
- ↑June is the first genuinely affordable month in Seychelles: prices drop below the moderate range for the first time since October, and some properties offer off-season rates that are remarkable relative to the January peaks; the beaches are as good as ever on the east coasts

September trade-offs
- ↓Early September still carries trade wind weather on the west coasts — the transition is gradual, and the first two weeks may see west-coast beaches still rough; the easing happens progressively through the month rather than on a specific date
- ↓September's 88mm of rain is similar to August — the transition between the two seasons doesn't significantly reduce rainfall, and afternoon showers remain part of the daily pattern; the improvement from August is primarily in sunshine hours (7.5 vs 7.0) and wind reduction rather than dryness
- ↓Demand from European autumn half-terms begins building in late September — accommodation in quality properties starts to fill for October, and September late bookings may find the best rooms unavailable
June trade-offs
- ↓The west-coast beaches that define the classic Seychelles postcard image — Anse Lazio, Beau Vallon, Anse Georgette — are exposed to the southeast trades and experience rough swell and wind from June through September; swimming at these beaches in June is possible in sheltered sections but the conditions are not the flat, glassy calm of the monsoon season
- ↓Water temperature drops slightly to 27°C in the trade wind season — still warm by any European standard but cooler than the 29–30°C of the northwest monsoon period; snorkelling is still comfortable but the warmest-water experiences are in January–April
- ↓Trade winds in the Seychelles are consistent but can be strong — June can see 20–25 knot sustained winds that make kayaking and paddleboard activities physically demanding; boat trips to outer islands can be bumpy in the inter-island channels
