Most of us make assumptions about a wide variety of things because it generally saves us time and we are often correct. One example that I’ve heard from many people is the assumption that summers in the Caribbean are both wet and scorching at the same time. But for the most part, it isn’t true, and the weather is actually much nicer than you’d expect.
Part of the problem seems to come from the fact that people who live in, say, Atlanta or Houston experience a very hot and humid summer, so they figure that getting closer to the equator will only make things worse. Weirdly enough, that’s not how it works, and hurricanes and other storms are actually very rare as well.
It’s nicer in the Caribbean than your home town in summer
While it is the hottest time of the year, through most of the summer, temperatures in the Caribbean only average about 88F/31C or 90F/32C most days. The cool part of it is that it almost never goes above that either. When it’s much hotter than that in your hometome during a heatwave you might assume that it’s very hot everywhere else too, but in the Caribbean every day is almost the exact same.
The low temperatures in most of the region hover around 75F/24C most nights as well. When you are out on or near the beach, a breeze feels wonderful and this is pretty much an ideal temperature for dinner and drinks after the sun sets. And of course all the rooms have air conditioning, so you’ll have no problem sleeping or taking an afternoon nap during the hottest part of the day.
Big storms are extremely rare in any given place and time
The biggest reason why resorts on islands like Dominican Republic and Jamaica are cheap and half empty during summer is that people are worried about hurricanes. Every other year or so, there is a big one that hits one of the islands and might even cause some deaths. People remember that, and incorrectly assume that they might be next if they dared go to the Caribbean during the season.
However, the reality is that the Caribbean is enormous, and even when one island gets hit every other year, there are about 30 islands that aren’t hit in any given year. Imagine you heard that summer is tornado season in the middle of the United States, so you decided to avoid the whole region for the whole season. It doesn’t make sense to avoid 15 states because at some point there might be one city in one of them that has a tornado.
More dramatically, hurricanes are also tracked for about a week before they hit any islands, so even if you get incredibly unlucky, it only means flying home early or flying in a day or two late. All the resorts in the islands have storm preparations to get guests out at least a day or two before a possible storm hits, so the risk is basically zero, except for a tiny risk of being inconvenienced and having a fun story to tell later.
