The Seychelles sit just south of the Equator, resulting in year-round sunshine and temperatures that hover around 30°C. Tropical showers are to be expected throughout the year, and though humidity is high, the cooling sea breezes do a great job of tackling this. The northwest trade winds (November – March) and the southeast trade winds (May – September) can cause choppy seas and a build-up of seaweed on some of the beaches. This could be a factor to consider when deciding which side of the island you stay on at different times of year.
As well as experiencing the northwest trade winds, the period between January and March is hot and humid with some rainfall. For those who wish to see the magic of turtle hatchlings, then these months provide your best opportunity. The winds start to subside a little in April, but the climate retains its heat and humidity.
The southeast trade winds start picking up in May and carry on until September, so we would advise staying on the west coast of the island. September marks the onset of whale shark season which reaches its peak in October – an excellent time for divers. October is also the period when hawksbill turtles start to lay their eggs, which they continue to do up until December. The northwest trade winds arrive in November, so the east coast of the island now becomes more favourable. You can expect some more rainfall as well as more visitors in the run up to the festive period.
