June is the first official month of the Caribbean hurricane season, but storm activity is light and hurricanes are rare. The region does have an increase in total rain versus May.

Over a 30-year history, the Caribbean in June has experienced an average of one tropical storm and no hurricanes, according to the U.S. National Hurricane Center. By comparison, July sees three tropical storms of which two become hurricanes.

Storm and hurricane activity climb each month until they reach a peak of four storms with two becoming hurricanes in September.

Best and Worst Rainfall

Aruba has the lowest rainfall of all the destinations in June with only one inch on average, but that is mostly true of Aruba year-round. It is popular during the peak months of the hurricane season because it usually avoids the worst of the weather.

Antigua and St. Maarten weather in June historically also have lower than average rainfall. Many other islands average about four to five inches.

A handful of destinations known for rain forests have even higher amounts of rain. Most of them are Central American countries that are popular with western Caribbean cruises.

Belize and Costa Rica, which are major stops on western Caribbean cruises, have the highest rainfall. Both destinations usually have high rainfall throughout most of the year, which is why they are known for their lush rainforests. The highest amounts of rainfall for these Central American countries are usually inland rather than their cruise ports on the coast.

The title for worst rainfall in June is the Bahamas. Even though Belize and Costa Rica have more, the Bahamas are unusual for getting so much more rain than normal in June compared to other Caribbean islands.

The average number of days that it rains varies widely from one destination to the next. Punta Cana, Montego Bay, San Juan and Aruba all have lower than average days when it rains.

Best and Worst Temperatures

Hot weather hits Aruba, Cancun, Cozumel and the Cayman Islands with average daytime temperatures above 90 degrees Fahrenheit or 32 degrees Celsius.

Most other destinations hover in the mid to upper 80s Fahrenheit during the month.

One exception is Costa Rica, which has lower overall temperatures in part because of mountains and rainforests.

Average nighttime temperatures hover in the mid 70s Fahrenheit or about 23 to 25 Celsius. Sea water will be comfortable for swimming.
