Caribbean Monthly Weather: Rain: Temperatures
Caribbean monthly weather ranges from the low 80s Fahrenheit or high 20s Celsius in the winter to the high 80s Fahrenheit or low 30s Celsius in the summer.
Rainfall is moderate from January through April during the dry season and heavy from August through November during the peak months of the Caribbean hurricane season.
There are some exceptions. Aruba, Curacao and Bonaire are arid islands with light rainfall for most of the year until October through December; even then it is moderate by Caribbean standards.
Destinations such as Cancun, Cozumel and Grand Cayman will often have daytime temperatures reach into the low 90s Fahrenheit.

Cool and Popular
January, February and March are dry times in the Caribbean with most destinations averaging about two to three inches of rain. Daytime temperatures are warm, but nighttime temperatures are much cooler than normal.
Ocean currents from the north will bring cooler waters south and sometimes make water uncomfortable for swimming. Southern destinations such as Aruba have the warmest water.
Because of this dry season, western Caribbean cruises in particular jump up. March often sees a spike in vacations because of families and college students going on spring break.

Meanwhile, storm and hurricane activity start to climb and reach a high point in September.
Caribbean tourism plunges in September because of higher risk for storms as well as children returning to school.

Hurricanes End, Winter Begins

November is the final month of the hurricane season even though storms are few and hurricanes are rare.
The number of visitors to the Caribbean jumps in December as people up north look for a break from the beginning of wintery weather.
