July is early hurricane season in the Caribbean, but your chances of having your July vacation blown away are pretty small: between 1851 and 2006 there was less than one July hurricane per year (0.6, to be exact). July temperatures typically range from about 78 F to 87 F, and summer humidity levels are present on many islands, although you still may find the temperatures in the Caribbean more comfortable than the dog days of summer back home.
Average days with rain in July: about 11.
Visiting the Caribbean in July: Pros
Low-season rates are the biggest attraction, plus warm, mid-summer temperatures throughout the region, including the Bahamas and Bermuda.
Visiting the Caribbean in July: Cons
Some destinations may feel a bit "dead" at this time of year, and not every attraction may be open. For Bermuda, however, July is the height of high season. Tropical storms and hurricanes begin to become a concern, but not a big one.
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 sunscreens, a hat, and sunglasses.
You’ll want dressier clothes for visiting nice restaurants or clubs -- and bring more formal footwear than just flip-flops and sneakers.
July Events and Festivals
July is the height of the reggae season in Jamaica, and some islands also celebrate Carnival this month.
