Divers of every experience level will enjoy a visit to the pristine coral reefs of the Florida Keys National Marine Sanctuary on our Key West Scuba afternoon dive trip. Let an expert local captain be your guide to the best Key West coral reef dive sites, the spots where favorable currents, excellent visibility, and an incredible number and variety of tropical fish and many other marine species make it clear that Key West scuba diving truly is world class. Dedicated scuba experts, visitors looking to do a couple of fun dives while visiting the island, newly certified beginners working to build their dive count, and non-diving friend and family members who want to swim and snorkel can all have a great time on these afternoon 2-tank trips.

The Florida Reef, the third largest coral barrier reef system in the world and the only living coral reef in the continental United States stretches for 170 miles along the length of the Florida Keys. There are more than 6,000 individual reefs in the entire system, and the portions near Key West lie about six miles off the Atlantic side of the island in depths ranging from around 15 to 30 feet. Specific sites for the Key West scuba afternoon dive trips are chosen based on daily water conditions, with the typical reef dives happening in 10 to 40 feet of water. Because of the protection offered by the Florida Keys National Marine Sanctuary, even these close-in shallow waters present divers with a reef ecosystem of amazing diversity and complexity.

A scenic 40 minute cruise on a state-of-the-art high speed dive boat equipped with all modern amenities brings divers into a marine environment that is home to nearly 1,400 species of marine plants and animals, including 500 species of fish and more than 40 species of stony corals. Hundreds of species can be seen on each dive, including all kinds of colorful tropical reef fish, the larger predatory fish such as Barracuda, Grouper, Jack Crevalle and Cobia, and other marine life such as eels, rays, and turtles. Key West reef diving is truly spectacular, and easily rivals many of the exotic locations found outside the US. The sheer size of the reef system, the huge variety of dive sites and conditions, and easy accessibility from Key West make dives on the Florida Reef a top attraction on the Key West scuba diving scene.

Where is the reef?

The Florida Keys host the Third Largest Barrier Reef in the World as well as North America's only Living Coral Reef. With that said, our barrier reef extends from Key Biscayne to the North and travels to the south on the Atlantic side all the way to the Dry Tortuga's and Fort Jefferson. There is over 210 miles in total length of reef. If you were to dive in Key Largo and Key West you are diving on the same reef system. This reef lies approximately 5-6 miles off shore and is a half hour boat ride on the M/V Phoenix.

What are your typical dive conditions?

There are many different factors that affect our diving conditions. Summer months bring the most ideal conditions for the keys with water temperatures in the upper 80's, calmer winds/seas and clear visibility. These conditions can last well into October and November . In December we start to get cold fronts. These weather patterns bring stronger winds from the North and can create heavier seas and can lower the visibility. Spring time can also bring steady East to North East winds that again can cause wind waves and stir up visibility. 

We also have two different bodies of water that are constantly in motion. To the south of the keys lies the Atlantic Ocean and to the North we have the Gulf of Mexico. These two bodies of water are always in flux and can affect visibility tremendously. When The Gulf Stream Current (a warm water mass that circulates around the Caribbean) is closest we have cleaner and clearer water. When the Gulf of Mexico is on the Reef we tend to lose our visibility. 

The most important weather factor that you would want to keep informed about is the wind speed and direction. Strong Southerly winds can create larger seas as there is no protection from any land mass whereas wind waves from the North can be blocked by the Island chain. Our prevailing winds in the keys is North and North East Winds. So always check the wind speed and direction. Our summer squalls are short and the rain does not affect the visibility at the reef. 

The captain takes all of this into account and will attempt to take all divers to the clearest calmest waters possible.

What is the best time of year to dive?

The summer months from May to September are the most ideal conditions for diving in the Florida Keys.

Is there a restroom on the boat?

Yes, there is a restroom or a "head" in nautical terms. Please remember that all marine toilets have smaller plumbing and do not act like toilets on land. Please use the trashcan near bye for all tissue products, feminine products and other trash.

Will there be a dive master or instructor in the water with me?

We allow all certified divers to explore on their own. The United States Coast Guard requires the Captain and Dive Master stay on deck to respond to any emergencies. The instructors and other Dive Masters on the boat will typically dive with their respective students. A private dive master can be arranged if you want.
