The Lesser Antilles span several islands, countries and forecast services. A charter among Martinique, Guadeloupe or the Grenadines needs a fresh local product at each end and an offshore picture for the open passages between them.
Official marine-weather sources
Météo-France Martinique marine and Météo-France Guadeloupe marine provide coastal and offshore products for their respective territories. The NHC Caribbean offshore directory and tropical advisories add basin-wide context. For other islands, seek their responsible national service rather than extending a French bulletin beyond its area.
Check before a passage
- Locate the windward and leeward sides of each island and the exposed channel between them.
- Check squalls, cross-island wind changes and swell at the planned anchorage time.
- List the official source and advisory update time for each territory on the itinerary.
What this page does not do
No island group has one universally representative forecast. This guide is a navigation aid to primary sources, not a live tropical warning.
This is not a live forecast or a personal route recommendation. Before departure, check current warnings, issue time and zone boundaries at the original source. AI-assisted and expert personal briefings are in development.
