West Bay's dive sites are defined by a consistent pattern of shallow reef shelves giving way to walls and drop-offs, with several sites offering both environments in a single dive. Shore entry is available at a number of sites, making the area accessible without a boat, though boat-access pinnacle and wall dives like Ghost Mountain add deeper, more dramatic topography for intermediate divers. The species list is notably rich, with French Angelfish, Queen Angelfish, Nurse Shark, and both Brazilian Reef Octopus and Caribbean Reef Octopus all observed regularly across sites.
Monthly water temperature across West Bay's sites, from satellite sea-surface data corrected for depth. The band shows the site-to-site spread.
Water stays warm throughout the year, with the coolest months still comfortable and peak warmth running through the summer and into autumn. The best-months data favours the cooler, calmer period from late autumn through early spring, when settled conditions tend to deliver the clearest water. Exposed sites can pick up swell at any time, so checking conditions before heading to shallower shore-entry sites is worthwhile.

Fin maps 12 sites in West Bay (11 scuba diving sites and 2 snorkelling spots, with some suited to both).
West Bay has a well-documented species list built from actual sightings. Indian Lionfish and both French Angelfish and Queen Angelfish are observed at the vast majority of sites. Nurse Shark, Brazilian Reef Octopus, Caribbean Reef Octopus, Great Barracuda, Spotted Moray, and Green Moray are all commonly recorded too, making for varied encounters across a single trip.
A good proportion of West Bay's sites are rated for beginners, including Spanish Bay Reef, Turtle Farm Wall, Turtle Reef, and Bear's Paw. Several of these are shore-accessible with shallow starting depths, so newly certified divers have plenty of suitable options. Intermediate sites like Ghost Mountain and Cobalt Ridge are available once divers are comfortable with walls and greater depth.
Both options exist in West Bay. Sites such as Turtle Reef, Turtle Farm Wall, and Spanish Bay Reef are accessible directly from shore. Boat-only sites like Ghost Mountain and Bear's Paw are served by several operators in the area, including Divetech, Ambassador Divers, Ocean Cabanas Resort, and Cayman University Divers.
The predominant pattern in West Bay is a reef shelf that transitions into a wall or drop-off. Cobalt Ridge offers both a shallow reef and a wall drop-off within the same dive, while Ghost Mountain adds a pinnacle structure to the mix. This variety means divers can experience quite different topography across the sites without travelling far.
