Seychelles marine weather for island passages

The inner Seychelles and remote outer islands are not one forecast location. A Mahé–Praslin charter, a passage toward Amirantes and a longer Indian Ocean leg need different coverage, communication and alternatives.

Official marine-weather sources

The Seychelles Meteorological Authority marine forecast divides its product into Mahé/Praslin/La Digue, Amirantes and Aldabra groups. Read the current warning and the relevant area, then check the issue time and the next bulletin. For a route beyond Seychelles waters use the WMO/IMO METAREA directory to identify the next issuer.

Check before a passage

  1. Match the actual island group and open leg to the authority area.
  2. Compare wind and wave direction with the arrival anchorage and alternative, not just the forecast at departure.
  3. For outer-island passages, establish how fresh warnings will reach the yacht away from mobile coverage.

What this page does not do

A 24-hour regional forecast cannot validate an entire multi-day ocean itinerary. Reef approaches and permissions require separate current information.

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.
