Most of my reef dives here range from 60-90 feet maximum depth. A quick check of my dive computer shows most of my first dives range from 80-100 feet and second dives were 50-60 feet. These are all boat dives leaving from Christiansted. Typically the first dive is a wall or deeper reef and the 2nd is a shallower reef. On the deeper dives, you could easily dive them shallower by exploring the upper part of the wall while following the group. Also, most of my afternoon dives show both dives being shallower reefs. These afternoon dives tend to include people who are completing a resort course, so tend to be shallower and also much shorter boat ride (although they all feel relatively short here). If you prefer the shallower reefs, I'm sure any of the dive shops would accommodate.So St. Croix seems to be the place for shallow reef diving.
How deep are the reefs in St. Croix?
How is the diving in the winter time? I know the summer months are better for diving in areas like the Keys, and wondering if St. Croix would be nice enough to dive in the winter months since it's further southeast?
Not a huge amount of difference between summer and winter diving here. Winter dives range from 78-79 degrees and summer dives hit 84 degrees according to my computer. In the winter we do get seasonal winds, but in the rare instance you couldn't dive the north side of the island, the west end (Frederiksted) would usually be flat. I personally have never had a dive canceled due to weather here.
