For anyone planning an eastern Caribbean cruise, the region starts with the Bahamas to the north and even Bermuda more north, although neither location actually lies within the Caribbean Sea.

The area includes: Antigua, Bahamas, Bermuda, St. Kitts, St. Lucia, Turks and Caicos, and U.S. Virgin Islands.

Others include British Virgin Islands, Dominica, Guadeloupe and Martinique.


Eastern Caribbean temperatures throughout the year average nearly 85 degrees Fahrenheit and a low of about 73 degrees.

Guadeloupe, St. Lucia, St. Maarten and the Virgin Islands have the warmest average temperatures.

These destinations have consistently warm temperatures year round and are popular for that reason during the winter.

Bermuda is the coolest destination in the group because of its northern location, followed by the Bahamas.

These two destinations are cool enough in winter that the seawater is uncomfortable for swimming. But they remain fairly popular during the cooler months because of golf and their convenient access from the states.


Rainfall averages 5 inches per month with Dominica and Martinique getting the most, which is why they are known for their lush rainforests.

Antigua, St. Maarten and the Virgin Islands get the least rain.

However, most of the destinations get their highest rainfall in September, October and November because of the Caribbean hurricane season.

As a result, all of them see a big dropoff in tourism during those months.
