Cayman Islands weather will give visitors one of the hotter Caribbean experiences.
The Caribbean is known for warm weather, but most destinations have average high temperatures in the 80s Fahrenheit. The Cayman Islands is one of the few that exceeds 90 during the summer and even into the fall.
Besides hot weather, a vacation there means a chance for duty-free shopping and excursions such as Sting Ray City, one of the most popular tourist excursions in the Caribbean where visitors can jump into the ocean and swim with a school of friendly sting rays.
Cayman Islands Temperatures
The average maximum monthly temperature is 89.5 degrees Fahrenheit year round, which is one of the highest averages in the region, according to the World Meteorological Organization.
Average monthly temperatures exceed 90 degrees from May through November. Maximum temperatures average about 87 degrees in December, January, February and March.
These islands are unique for their warm days and cool nights.
The average monthly low temperature is 70.1 degrees, which also is one of the lowest regional averages.
The average low drops into the mid 60s from December through March. When temperatures drop that low in the Caribbean, sea water becomes uncomfortable for swimming.
The islands receive an average of 4.7 inches of rain per month. It typically rains 14 days a month.
Rainfall is moderate from January through April at 1.7 inches per month. Rainfall more than triples in May and climbs from there to September and October, when it averages 8.3 inches a month.
The islands receive much higher total rain than the average Caribbean destination in September and October.
The same is true for the number of days it rains each month. It rains 20 days in September and 19 days in October compared to less than 10 days in January through April.
When to Go
The most popular months to visit are March, April and December, according to the Caribbean Tourism Organization. March is popular despite low temperatures.
The least popular month is September, followed by October — right in the middle of the annual Caribbean hurricane season.
Vacationers wanting to experience the best Cayman Islands weather will find that April is the best month to go for warm but not uncomfortable temperatures and the fewest rain days.
Other good months are March, May, June and July. Avoid going there in September and October if possible.
