The enjoyment of Guadeloupe's coasts, ports and moorings depends primarily on their windward or leeward exposure. As a matter of fact, the Trade Winds blow fairly regularly all year from the east to northeast sector in accordance with the seasons. It has a strength from 3 to 5 on the Beaufort scale in the Winter, more variable in strength and direction in the Summer, and followed by the hurricane season from August to October. The winds die out frequently along the leeward coasts. Visibility is generally good , except in squalls that are frequent but short.
Fog is non-existent.
Only the currents they bring about are important for navigation. When the Trade Winds blow a cool breeze for several days, the sea may become difficult to navigate in the channels between the islands. The radius of the light is not always proportional to its range. The speed within this zone is limited to 5 knots. The islands are connected by two draw bridges each with a 4 meter overhead.
