Seychelles' weather

At the Seychelles you will find good weather all the year around. The climate is tropical, but is always pleasant thanks to a constant sea breeze, with average temperatures of the order of 25 and 30 degrees centigrade (77 to 86 F°).

The Seychelles are outside the cyclone zone and the rainstorms are therefore few and far between.

There are two principal seasons dominated by trade winds that blow in opposite directions: the period from October to April, touched by the wind of the north west is warmer, with more rainfall but of short duration and the sea is generally calm. From May to September temperatures are slightly lower and drier climate due to the winds of the south east.

The periods of calm between the trade winds in April / May and October / November, have a warmer climate without winds and the sea is calm and clear.

The best time to go depends on what you want to do.

  • For diving and snorkelling the best times are from March to May and from September to November. In addition SUBIOS, the festival of underwater photography and movies is held on October each year.
  • For bird watching the best times are in April to coincide with the season of love. May-September for the nesting of the terns and October for birds migration.
  • For the deep-sea fishing the period from October to April is recommended while surfing and windsurfing are ideal in the months from May to September.
