September is the Perfect Month for Florida Keys Tourism

Travel Tips, Weather, Events and Deals

When September arrives, the summer crowds have left the island chain. With a calm and tranquil month ahead, September offers a great opportunity to catch a vacation deal. While Labor Day creates the perfect excuse for a long leisurely weekend, you can find plenty of off-peak travel periods to help you save more and stay longer in our hidden oasis. Seniors can also take advantage of our special offer for a vacation in the Keys, throughout the year. Discover the ultimate home-away-from-home for friends traveling together in our spacious two and three-bedroom Florida Keys beach houses, or relax on a romantic retreat surrounded by serene greenery in the Tropical Garden Guestrooms.

Marathon Weather in September

As the summer heat starts to cool down across the United States, Marathon maintains an average high temperature of 88° F (31° C). The water temperature may be around the mid-80s (30° C), but the sea is still perfect for ocean activities such as swimming, snorkeling or diving. September often brings afternoon thunder storms, but the rain rarely sticks around long enough to spoil an entire day.

You may be concerned about the Atlantic hurricane season as you plan your vacation in the Keys. Hurricanes may affect the Atlantic and Gulf coasts of the United States from June 1st through November 30th. Traditionally August 15th through October 15th presents the highest potential for storms. Tranquility Bay Resort offers a hurricane clause to protect our guests during this period so please inquire within our call center.

What to Wear in September

The Florida Keys still experience summer weather throughout September. Pack your summer gear, including flip flops, a swim suit, shorts and a light shirt, but be sure to bring light layers that you can add to your wardrobe when needed. If you go boating for example, bring a light jacket. Don't forget protection against the sun. We highly recommend that guests bring sunglasses, aloe or after sun cream, sun screen and a hat to protect you against UV rays.
