June is the official start of hurricane season in the Caribbean, but your chances of having your June vacation blown away are slim: there were only 28 June hurricanes in the Caribbean between 1851 and 2006, for example, compared to 319 in the month of September, and even if there are hurricanes, the chances of one hitting land are incredibly slim.
June temperatures typically range from about 78 to 87ºF, and summer humidity levels begin to pick up in many islands during June.
On average, about 10 days in June will see some rain. At night, temperatures stay within the 70 to 80ºF range due to the ocean air. Also of note, the Caribbean Sea temperature ranges from about 81 to 82ºF in June.
The rainiest weather is going to be found in the more northern islands, including Cuba and the Bahamas, while the driest islands will be in the southern region—Aruba, Bonaire, and Curacao—as the dry season comes to an end.
Visiting the Caribbean in June: Pros
Low-season rates are the biggest attraction, plus warm, mid-summer temperatures—beach weather—throughout the region, including the more northerly Bahamas and Bermuda, even while mainland North America may still be experiencing some cooler days and evenings. Plus, there are fewer crowds, the beaches are practically empty, and if you prefer a more laid-back, intimate trip, there will be far fewer tourists, especially if you go before schools let out in June.
Visiting the Caribbean in June: Cons
Some destinations may feel a bit "dead" at this time of year, and not every attraction may be open. Tropical storms and hurricanes begin to become a concern, but not a big one, and there are certain destinations where you can almost guarantee limited rainfall.
What to Wear and What to Pack
Loose-fitting cotton layers will keep you cool during the day, especially on islands where the climate is more tropical and humidity can be an issue.
Don’t forget a swimsuit, plenty of sunscreen, a hat, and sunglasses. Though most places will provide poolside towels, you may also want to pack your own beach towel if you have a particular preference in size. Also, depending on the weather, a light jacket may or may not be needed at night, and if you're worried about that early-hurricane season rainfall, a rain jacket might also be a good choice.
You’ll want dressier clothes for visiting nice restaurants or clubs, and it's always a good idea to check the dress code policy before going out; some places require a sports coat, some require a collared shirt, etc. You'll also want to bring more formal footwear than just flip-flops and sneakers.
June Events and Festivals
There's no big signature Caribbean event in June, but a number of islands celebrate Labor Day this month, while those with English heritage honor the birthday of Queen Elizabeth II. Crop Over in Barbados and Carnival in St. Lucia are other highlights.
And, as always, keep an eye out for weekly events going on at your resort or hotel. Even if there are no island-specific events happening, there is almost always some kind of entertainment happening every night, from cover bands to dance clubs to limbo contests and more.
