Marine Life

Larger pelagic species such as sharks (hammerheads are common), manta rays, sea turtles, and occasionally even whale sharks are frequently sighted. Macro life enthusiasts will appreciate the abundance of invertebrates, including nudibranchs, crabs, and shrimp.

Best Time to Visit

September and October can also be good, but hurricane season should be considered. Visibility may be reduced after storms.

What Makes It Special

The Flower Garden Banks boast some of the healthiest coral reefs in the Caribbean and Western Atlantic. Massive brain corals and star corals dominate the landscape, creating a truly unique and breathtaking underwater environment. The isolation of the banks has helped to protect them from some of the stressors impacting other coral reefs around the world. Regular spawning events of coral colonies are also a unique spectacle for divers lucky enough to witness them.

Practical Tips

Given the depth of the dive sites, Nitrox is highly recommended to extend bottom time and reduce nitrogen narcosis. Strong currents can occur, so be prepared to swim against them. It is essential to book your trip with a reputable dive operator experienced in diving the Flower Garden Banks. These trips are typically multi-day liveaboard excursions. Finally, remember to be a responsible diver: avoid touching the corals and respect the delicate marine environment.
