Southern Caribbean weather is attractive to vacationers throughout the year because of its steady warmth both in the air and in the water.

The area generally covers the islands that lie closest to South America starting with St. Lucia in the north down to Trinidad in the south.

Seven of the largest destinations are Aruba, Barbados, Bonaire, Curacao, St. Lucia, St. Maarten and Trinidad.

Aruba, Bonaire, Curacao and St. Maarten make up the Netherland Antilles, along with Anguilla, St. Barts and Saba.

Most of these destinations are popular southern Caribbean cruise ports.


Weather in the southern Caribbean has an average high temperature throughout the year of nearly 87 degrees Fahrenheit and the low is about 76 degrees.

High and low temperatures are consistent throughout the group.

As a result, air and sea water temperatures are comfortable for vacationers even during the winter. But rainfall is not so predictable.

The average monthly rainfall is three inches for each island, but it varies wildly depending on the island and the time of year.

Barbados, St. Lucia and Trinidad receive the most rainfall, while arid Aruba receives the least.

Aruba's low rainfall makes it a popular destination because of the low risk of bad weather and the fact that it lies outside of the Caribbean hurricane belt.

But it can still feel the brunt of a nearby hurricane.

Rainfall is heaviest in September, October and November, but again the worst rainfall hits Barbados, St. Lucia and Trinidad, while the lightest amount goes to Aruba.
