Visibility Breakdown
Visibility by position
Solid = diver report · outlined = today's forecast

Post Break: The range past where any waves are forming, where the water starts to have a significant increase in visibility. There might be some sediment here, but swell energy is diffused and the water is calmer.
Open Water: This zone is far out enough from the shore that the water is at its clearest. It’s deep enough that sediment is not disturbed by the wave energy at the surface. Haze can sit near the surface, so the water is usually clearer the deeper you go.

About Coral Reef (Anacapa)
Coral Reef lies on the seaward side of the west end of West Anacapa Island, a set of two or three rocky reefs running parallel to the island in twenty-five to ninety feet of water. The name comes from the dive community rather than from any hard coral. The reef has no tropical coral at all and is instead carpeted with encrusting anemones and sponges in lavender, yellow, pink, and orange, plus a famous brittle-star carpet between sixty and eighty feet that is the deepest section of the site. The dense invertebrate cover and the brittle-star carpet make it one of the most photographed dive sites in the park.
