Located in the western Indian ocean, the Seychelles islands are located just south of the equator, and have an equatorial / tropical climate. The temperatures undergo minimal seasonal variations but are mitigated by the breath of the monsoon winds.
These winds also affect humidity and rainfall. The Seychelles have two seasons: when the north-west monsoon blows, it has a humid, hot and rainy season, and this occurs between November and April. While when the southeast monsoon blows there is the cool and dry season which corresponds to the months between May and October. The rains usually fall overnight.
The mountainous islands receive more rainfall than the coral atolls, the island of Mahé receives an average of about 2,200 mm of rain annually, Praslin about 1,500 mm, while the Aldabra coral atoll stops at 600 mm of rain per year.
The islands are located outside the area affected by hurricanes, so these are a rather rare event, only the southern archipelagos of the Amirante Islands, the Cosmoledo Islands, the Farquhar Islands and the Aldabra Islands can be affected by cyclones in the months of January and February.
The temperatures remain constant with minimal variations. The average maximum temperatures vary during the year between 31 ° C in March and April and 28 ° C in July and August, the average minimum temperatures remain around 24 ° C-25 ° C during the whole year. The sea water temperature in the Seychelles islands varies between 26 ° C and 30 ° C.
