While the Caribbean is eternally popular for travelers looking to escape the snow and hail of the winter months up north, the fall is also a great time to visit. The shoulder season is well-known for being a smart time to travel for cost-conscious vacationer, as hotel rates and airline tickets are cheaper. The water is warm enough to swim in for all year, while trade-winds keep much of this part of the world cool when you’re on island time. September is during peak hurricane season, however, so travelers should prepare in advance (and consider purchasing travel insurance).

Read on for your guide to visiting the Caribbean in September.

Urgent Seasonal Information for Fall in the Caribbean

Hurricane season in the Caribbean hits its peak in September, and while the odds of your vacation being affected by a tropical storm or hurricane are greatest during this month, the overall danger is relatively small. For example, the National Hurricane Center states that while September travelers to Puerto Rico have an 8 percent chance of encountering a hurricane, it only applies if you spend the entire month there. So, if you only stay one week, the odds of a hurricane hitting are just 2 percent, even in the heart of storm season.

This is a great time to travel if you want to avoid kids, as they are most likely back in school at this point. That being said, if you do plan on taking a family trip and your kids are not in school, September is a great time to get great deals on Caribbean travel because it is one of the less popular travel times. 

What to Pack

Since the temperatures will feel like summer, it's best to pack loose-fitting, breathable 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. It also would be wise to pack some rain gear, considering the weather can be unpredictable. You will also want to pack some dressier clothes for visiting nice restaurants or clubs and more footwear that isn't flip-flops and sneakers.

Keep these tips in mind for carrying personal belongings: Bring small bag to keep essentials and carry wallets in your front pocket. Bringing a small bag has two major advantages; it's easier to carry around and harder for someone to grab something out of your bag. Putting a wallet in your front pocket makes it harder for a pickpocket to grab without you noticing.
