More cruising boats are visiting this large island off the coast of Africa which receives the full force of the SE trade winds blowing across the Indian Ocean. The strongest SE winds are in July, August, and September. Madagascar is under the influence of these winds all year, although the southern limit of the SE trade winds moves up the coast from August to November. During this period variable winds are experienced in the southern half of the island, although most winds are from an easterly or northeasterly direction. Winds from these directions can blow quite strongly. In March, when the ITCZ is further south, the northern tip of the island loses the SE winds to NE and NW winds. Madagascar lies within the cyclone belt, although cyclones are not as frequent as in the Mauritius area. The South Equatorial Current splits at the centre of the island and runs north and south along the east coast. The current along the west coast is mostly south-setting.

As better sailing conditions will be encountered by sailing from Mauritius around the northern tip of Madagascar, directions as far as Cap d'Ambre are similar to those given for route IS55. Rather than sail a direct course to Cap d'Ambre, better conditions will be found if the northern tip of Madagascar is approached from the east. Therefore an initial course should be sailed for WPIS562 from where the route continues west along the same latitude to WP IS563 before altering course for the NW coast of the island. The nearest port of entry is at Antseranana.
