Visibility Breakdown
Visibility by position
Solid = diver report · outlined = today's forecast
Break Zone: The range of water where the waves break and sediment is stirred up.
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 Olde Port Beach
Olde Port Beach, also known as Fisherman's Beach, is a sand beach inside Port San Luis Harbor, immediately east of the Harford Pier. A drive-down launch ramp sits at the east end of the parking area and reaches the waterline at low tide. Point San Luis to the southwest blocks the prevailing northwest swell, so the water is generally calm. Avila Beach is roughly one mile east along the shore, and Fossil Point is roughly two miles east, past Avila at the far end of the bay.
