Caribbean Weather in April: Rain, Temperatures

Caribbean weather in April is so good that it’s one of the most popular months of the year for an island vacation.

What makes it so good? It’s one of the best months to visit the Caribbean for a combination of warm temperatures and low risk of rain. Average daytime temperatures stay in the mid 80s Fahrenheit or mid 20s Celsius for most Caribbean destinations. Rainfall averages a little more than two inches for most destinations as well, which is near the low point of the year.

The Caribbean is known for the annual hurricane season, which runs from the beginning of June to the end of November. The Caribbean’s dry season goes from December through April. May is a transition month with more rain than the dry season months but not as much as hurricane season.

Rainfall increases quite a bit during the hurricane season and peaks in September and October. April doesn’t have that problem with rain.

Western Caribbean in April

The peak season for western Caribbean cruises is January through March, especially in March during spring break for schools. Although March is more popular, April has warmer temperatures and the same low risk of rain.

Cruise weather conditions remain ideal in April for major western destinations such as Cozumel, Jamaica, Panama, Roatan and the Cayman Islands. Rainfall averages only about two inches during the month for each of them, according to the government meteorological agencies for each country.

Even places in the western Caribbean that normally receive high amounts of rain during most of the year such as Belize and Costa Rica have low average rainfall during the month.

Temperatures are much warmer as well, especially in Cozumel and the Cayman Islands when they start to move into the upper 80s Fahrenheit or 30 Celsius during the day.

Eastern destinations fare almost as well with many of them reporting rainfall averaging about two to three inches a month.

There are some exceptions. Both Dominica and Guadeloupe report about five inches of rain in April in recent history, but both of those locations have more rain than the rest of the Caribbean throughout the year anyway. They are known as lush eco-tourism destinations with rainforests and waterfalls.

Temperatures in the eastern Caribbean are not as warm as the western half of the region. Most islands report average daytime temperatures in the mid 80s Fahrenheit, but none reached in the upper 80s, unlike Cozumel and Grand Cayman.

Best Places for Warm Temperatures

Not all destinations in the Caribbean are perfectly warm all year round, especially some of the more northern destinations during the winter.

April does much better. On average, April temperatures reach into the mid 80s Fahrenheit during the day for most destinations with a few such as Aruba and Cayman Islands reaching the upper 80s and sometimes higher.

For anyone who likes it really hot, parts of Panama reach into the 90s Fahrenheit or low 30s Celsius.

Low temperatures drop into the low to mid 70s during the nighttime hours. As a result, seawater is often chilly during the early morning hours but more comfortable by late morning to early afternoon.

One exception to these high temperatures is Costa Rica, which has cooler temperatures around the inland mountains. It is more known as a cruise and eco-tourism destination rather than a beach destination. Shore excursions often go inland.

Best Places for Low Rainfall

Average rainfall is three inches or less for most places in the Caribbean with a few exceptions that are known for their rainforests—which of course are the result of higher than normal rainfalls.

Again, they include Dominica and Guadeloupe as well as Martinique. Even so, these three destinations have relatively low rainfall compared to other times of the year, especially during the peak of the wet season in the fall.

On the other hand, the ABC islands of Aruba, Bonaire and Curacao are nearly bone dry at about 0.5 inches of rain apiece.

Another consideration for rainfall is the rain days average, or number of days it rains on average during the month.

Most destinations in the Caribbean average fewer than 10 rain days, which is well below the norm for the Caribbean.

Cancun and Cozumel average only four days, which is one reason why they are so popular during April.
