The western Caribbean generally covers Jamaica, nearby islands and the Central American nations to the west of it that border the Caribbean.

Six of the largest destinations are Belize, Cancun, Cayman Islands, Costa Rica, Cozumel and Jamaica.


Weather in the western Caribbean has an average high temperature throughout the year of nearly 86 degrees Fahrenheit and the low is about 70 degrees, Costa Rica is the coolest destination in the group.

Rainfall is lower and temperatures are higher on the Caribbean coast of most Central American countries. Rainfall climbs and temperatures fall away from the coast.

The region also has higher than average rainfall than the rest of the Caribbean at about 5 inches a month with Belize and Costa Rica leading the group at more than 6 inches.

However, the heavier rainfall also is why Belize and Costa Rica are lush and popular as eco-tourism destinations.

The average number of monthly rain days is 11, which again is higher than the rest of the Caribbean. But Cayman Islands leads the group with an average of 14 rain days a month.

Best and Worst Months

The Mexican island of Cozumel is a major attraction for western Caribbean cruises, but it also experience major peaks and valleys with rainfall.

Average monthly rainfall exceeds nine inches in September and October during the height of the Caribbean hurricane season, making them the worst months to go.

The island has a a brief wet season in June with an average of more than seven inches of rain, according to the World Meteorological Organization.

March and April have less than two inches, making those months an ideal time for a trip.

The same pattern holds true for Belize and Costa Rica. Belize averages more than 10 inches of rain in June, September and October, although the heaviest rain hits the interior more than the coast. Less than three inches fall in February through April.
