Temperatures stay in a narrow range throughout the year, but rainfall has extreme highs during the rainy season and extreme lows during the dry season.

Western Caribbean cruise ports include Cozumel, Jamaica, Grand Cayman, Roatan and the Central American nations that border the Caribbean. Smaller ports include Yucatan and Santo Tomás de Castilla.

Cancun is another major destination, although it is not available as a cruise port. Cruise travelers can visit it from ports in Cozumel and Yucatan.

Average Weather

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

The region also has higher than average rainfall than the rest of the Caribbean with a monthly average of about 5 inches a month. Belize and Costa Rica lead 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 days with rain each month is 11, which again is higher than most of the Caribbean. Grand Cayman is an exception with an average of 14 rain days a month.

Best Months to Visit

The best months to visit the western Caribbean are December through April when rainfall averages about two to three inches a month for most of the islands and Mexican ports.

Temperatures are also about five degrees cooler on average. We have visited the Caribbean including the Caribbean coast of Mexica multime times and found that nighttime temperatures, trade winds and cool northern current made swimming chilly quite often.

So anyone who likes swimming should plan on visiting in March or April rather than December through February.

Worst Months to Visit

The worst time to visit the western Caribbean is June through November during the annual Caribbean hurricane season.

The Mexican and Central American ports often get hit hard with rain. 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. Cancun has similar weather.

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

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.
