Climate of Seychelles

The Seychelles Archipelago lies over the South-west Indian Ocean to the northeast of Madagascar. It comprises over 100 small islands scattered over a wide expanse of ocean between 4° and 11° South latitude and 45° and 56° East Longitude.

Because of its geographical location and maritime exposure the Climate of Seychelles is of the warm, humid tropical type with a strong maritime influence.

These islands do not experience a distinct dry season. Average rainfall of the driest month, July, is greater than 70mm and warm throughout the year, Average temperature of the the coolest month, also July, [27°C].

The Climate in Seychelles can be divided into main seasons, the Northwest Monsoon and the Southeast Monsoon separated by two relatively short Inter-Monsoon periods.

 

The Seasons

bulletSoutheast Monsoon - May to October

This is a relatively drier and cooler period when the wind flow over the Seychelles is dominated by the 'South-east Trades'  which reaches its peak in the month of July/August.
Precipitation during this period is normally light in nature and rather shot-lived.

bulletPre-Northwest Monsoon - November

This period is characterised by the shift in wind regime from Southeast to Northwest associated with the 'onset' of the rainy season proper. It is relatively warm with very light winds.

bulletNorthwest Monsoon - December to March

This is the principal 'rainy season' over the Seychelles and gets extremely wet in December and January with precipitation tapering off towards March. With the sun in the Southern Hemisphere, this period is also fairly warm. Winds are predominantly from the West to Northwest but generally light. This is also the Cyclone Season over Southwest Indian Ocean.

bullet Pre-Southeast Monsoon - April

This is the calmest and warmest period of the year as the winds die down before reversing to the Southeast.
