The climate of Seychelles

Seychelles has a tropical rainforest climate (Köppen climate classification Af); It is a humid but equable climate, with little temperature variations throughout the year. Seychelles is an island country in the Indian Ocean, on the eastern side of the Somali Sea. The islands lie approximately 932 miles to the east of Africa. Madagascar and Mauritius are in the south, and Maldives and Chagos lie towards the east of Seychelles. Mahe is the largest island, 835 miles away from Somalia's capital, Mogadishu. The vast waters of the Indian Ocean, southeast trade winds, and proximity to the equator influence the climate. The days and nights are of equal duration throughout the year.

Seychelles is an archipelago of 115 islands, situated just 4°south of the equator. The landmass of only 175 square miles consists of two distinct regions. The Inner Islands are made from granitic rock and are the world's oldest oceanic islands. Mahe, Praslin Island, Silhouette Island, and La Digue are the most important granite islands. The rocky islands have a narrow coastal strip and a range of hills in the center. The Outer Islands are coralline and mostly flat, with coral reefs at different formation stages. Southern Coral, Amirante, Alphonse, Aldabra, and Farquhar, are the five main groups in the outer islands that have no freshwater sources. Denis and Bird are two coral sand cays that lie to the north of the Inner Islands. Two coral reefs, Coetivy and Platte, are in the south of the granitic islands. Morne Seychellois is the highest point at 905 meters. The coastline of Seychelles is 306 miles.
