The Seychelles: a unique place for navigation

Written on : 13 October 2017

The Seychelles Islands

The Seychelles has 115 islands, each one as beautiful and haunting as the other. The Seychelles archipelago is scattered in the middle of the Indian Ocean, forming a group of inner islands and a group of outer islands, most of which are located outside the hurricane zone.

The 41 granitic islands of the inner group are grouped around the main islands: Praslin, La Digue and Mahé. Denis Island and Bird Island are two islands of coral that are also part of the group of Inner Islands. The navigation around these sites is rather easy considering the kilometres of authentic, wild, preserved coastline and numerous secret creeks and caves. The outer islands are 72 in number. They are coral in nature and form an arc turned towards Africa. The six distinct island groups in the outer islands are the Southern Corallian Group, the Amirantes, the Farquhar and Aldabra Group, the Alphonse Group. All are between 260 and 865 miles from the East coast of Africa.

Sailing around the Seychelles is an outing that deserves to be experienced at least once in your life, say the passionate.

Ocean conditions in the Seychelles

Surrounding the Seychelles, the ocean currents of the Indian Ocean can reach 0.5 to 1.5 knots, and this is because of the trade winds. Between the islands, the currents oscillate between 0.4 and 0.8 knots and increase near the promontories and obstructions. Note however that the tides are more felt than the ocean currents themselves. But they never reach more than one node, except in the channels that are between the islands or near submarine ridges.

High and low tides are asymmetrical and semidiurnal, six hours apart. In the spring, the tide can rise up to two metres and drop to 0.9 metres. Note also that during strong winds and high seas, the hollows can reach one to two metres. The rest of the year is however moderate.

Two winds in the Seychelles

From December to March a Northwest wind blows over the Seychelles. Often strong at sunrise, they can reach 5 to 10 knots. These winds bring intermittent rain and gain strength between December and March. They are, in fact, associated with cyclones on the Indian Ocean in the Southeast. But rest assured, the Seychelles are outside the hurricane circle, except for the more Southern islands.

From May to September, the trade winds of the Southeast are dry blowing all day and part of the night. From June to September, an average speed of 10 to 15 knots can be expected and gusts can reach 30 knots in July and August. During the change of direction of the trade winds between April and November, the sea is calm and the water is clear, this period is calm and without winds. On the other hand, due to their Southern location, the outer islands experience stronger winds during the trade winds coming from the Southeast. VHF Channel 16, the Coastal Radio Station of the Seychelles will give you the weather forecast. Ships can also make radio links.
