Since summer season begins in June, the vacation season begins as well. Book your trip as early as possible to have the biggest selection of staterooms. Plenty of cruise lines sail to the Caribbean, so research the benefits and extras of each one. If you're unfamiliar with cruising, you might want to enlist the help of a professional travel agent. They may know of deals and discounts that aren't available to the general public.
June is the beginning of the hurricane season in the Atlantic Ocean. That's something to keep in mind, but it shouldn't keep you from cruising to the Caribbean in June. During hurricane season, there might be some changes to your itinerary, as one port of call might be exchanged for another or skipped altogether. To keep the passengers safe, there may be delays in returning to port, meaning that flights may be missed, so try to keep the schedule around your June cruise flexible. You might also want to purchase travel insurance that will waive the "non-refundable" clause in your cruise contract. There are advantages to cruising to the Caribbean during hurricane season, and you may find special deals designed to fill the cruise ship.
As June marks the beginning of hurricane season, the chances of your cruise being affected are low. With the advanced weather technology available, the bridge crew knows exactly what is going on with the weather at all times.
Expect sunny, warm weather in the Caribbean in June and on your trip there as well. Keep all your valuables, including identification and any important papers, in your carryon bag so they won't get lost. Have a small tube of sunscreen in your carryon as well, as the sun might be hot when you board and you don't want to risk starting your cruise with a sunburn. Shorts and T-shirts will most likely be the norm, but bring pants and a lightweight jacket in case the evenings are cooler. Check with your cruise line about formal dinner wear. Other things you'll need include bathing suits, sunglasses and a hat. Don't forget comfortable walking shoes and flip flops to wear by the pool or on the beach in the Caribbean.
