December Weather in the Caribbean
With the threat of hurricanes and tropical storms past, December travelers to the Caribbean can look forward to average daily temperatures in the high 70s, with lows around 73ºF and highs of about 83ºF (temperatures in Bermuda and the Bahamas tend to be on the cooler side of the range). You might get rain on about one of every three days, but you won't usually get soaked this time of year.
Visiting the Caribbean in December: Pros
The few weeks before Christmas are filled with bargain rates on hotels and airfares, since this is typically a slow travel time. Many resorts cater to families looking to spend the holidays together. Since nearly every Caribbean island has a majority Christian population, it's easy to find local holiday celebrations regardless of where you travel. Christmas Cruises to the Caribbean are very popular. And, what's better than spending a few days in December on a beach?
Visiting the Caribbean in December: Cons
Early December may be a bargain, but hotel and airfare prices rise sharply for the holidays and especially for the week between Christmas and New Years, when many families have off from school or work. Seekers of a traditional White Christmas obviously will be disappointed, as will those seeking a typical U.S.-style holiday celebration (few shopping malls, palm trees in place of Christmas trees, sorrell instead of egg nog, etc.)
What to Wear and What to Pack
Bathing suits and summer-weight clothing for the days, perhaps a sweater at night, and don't forget some holiday finery, especially if you plan to attend Christmas Mass.
December Events and Festivals
