Grenada Cruising Conditions
General Conditions
Winds are nearly always NE-SE at 10-25 knots, intensifying around the northern ends of islands; calms are rare. Rain usually arrives in squalls seen approaching from windward, and typically squalls can have strong gusts. Visibility is normally over 10 miles, but reduced in squalls.
June to November is the hurricane season for the Caribbean, but Grenada is south of the area most affected. If conditions exist for hurricane development, we request very close contact with the base while clients are on charter.

Tides
- In the Caribbean the tide range is very small: 30 cm to 90 cm (1-3 ft), including the variation of level due to atmospheric pressure and dominant winds.
- Current is normally westerly up to 2.5 knots.
- Those making passages among islands should take this into account.
Weather Forecasts
The base provides weather forecast for the next 24 hours. Guests should consult the “Sailors Guide to the Windward Islands” for AM/FM stations from Martinique to Trinidad. There are locations at Blue Lagoon St. Vincent, Tyrell Bay, Clifton Harbour and Bequia where forecasts are posted daily. Radio reception can be very poor in the islands. Reports can also be obtained by calling The Moorings bases by cell phone.
