Reef & Fish Info

Town quiets down a bit as families get their kids back to school so Key West scuba diving in September is a good way for couples to take a peaceful, fun vacation break. Water temps remain in the pleasant high 80s and apart from a few breezy days, sea conditions and visibility are generally good.

September Weather Outlook
Summer holds on into early fall in Key West and air temperatures are still averaging 86°F by the end of the month. Tropical storm season keeps chances of rain at over 50% throughout the month, mostly in the form of scattered showers. Winds stay low but average speeds do increase to 11.3mph from the east by month’s end.

September Marine Life
Out on the wrecks, Goliath Groupers are readying for the fall spawn and schools of Sharks gather for migration season. Keep an eye open for Spiny Lobsters tucked into the reef crevices.

Activity name

Key West Scuba Diving wants to make your searches as relevant as possible. That's why we offer many ways to help you find the right experiences for you.

On some pages, you can select how to sort the results we display and also use filter options to see only those search results that meet your chosen preferences. You'll see explanations of what those sort options mean when you select them.

If you see a Badge of Excellence label, the award is based on average review ratings, share of bookings with a review, and number of bookings through Key West Scuba Diving over a 12-month period.

The importance of any one factor over any other in a sort order varies, and the balance is constantly being reviewed and adjusted. We're always updating our systems and testing new ways to refine and improve your results to make them as relevant as possible to meet your needs.
