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 Morro Bay Outer Breakwater
The Morro Bay Outer Breakwater is the rubble wall that runs 600 yards south from Morro Rock and closes the north side of the harbor entrance. A light on a white column stands 36 feet above the water at its outer end. The dive is the harbor side of that wall toward the seaward end, where NOAA charts 23 feet, and divers who work it know the site as the Outer Break Wall. The wall is rubble rather than a smooth face, and big lingcod are among what the gaps in it hold.
