The islands lie outside the cyclone belt but receive monsoon rains from November to April with the northwest trade winds. This hot and humid season gives way to a period of cooler weather, though the temperature rarely falls below 23°C (73°F), and rougher seas when the trade winds blow from the southeast (May to October).

Tropical lightweights, with rainwear advisable during the rainy season. Sun hats and sunglasses essential all year round.

The Seychelles Archipelago occupies 400,000 sq km (150,000 sq miles) of the Indian Ocean northeast of Madagascar and contains 115 islands and islets. These fall into two groups of markedly different appearance, stemming from their distinct geologies: Granitic: A dense cluster of 43 islands, the only mid-ocean group in the world with a granite rock formation. Their lush green vegetation is tropical in character, with a profusion of coconut palms, bananas, mangoes, yams, breadfruit and other tropical fruit. Indigenous forest exists on the higher slopes, where cinnamon and tea are planted. All, including the second largest, Praslin, are less than 65km (40 miles) from Mahé. Coralline: Isolated coral outcrops speckling a vast area of the Indian Ocean to the southwest of the granitic group. They rise only a few feet above sea level but are covered with rich and dense vegetation due to fertilisation by copious amounts of guano. There is no permanent population. Aldabra, the largest atoll in the world, contains one-third of all Seychellois land and is a UNESCO-designated World Heritage Site. The largest island in either group is Mahé, lying 4°S of the equator. It is 27km (17 miles) long by 8km (5 miles) wide and contains Victoria, the capital and main port, and 90% of the population. Mahé is typical of the Granitic Islands, being mountainous and covered with jungle vegetation. Its highest point, indeed the highest point in the Seychelles, is Morne Seychellois (905m/2,970ft). The isolated nature of the Seychelles has given rise to the evolution of many unique species of flora and fauna, including the coco-de-mer palm and unique varieties of orchid, giant tortoise, gecko, chameleon and ‘flying fox’ (fruitbat). National parks and reserves have been set up to protect this heritage. The Seychellois are descended from a mixture of French and British landowners, freed African slaves and a small number of Chinese and Indian immigrants, creating a unique culture.
