Cross-section from the sand out to open water, split into 3 visibility zones: Break Zone (0-50 ft from shore), Post Break (50-200 ft from shore), Open Water (200+ ft from shore).
Shore
Break Zone
0-50 ft from shore
Post Break
50-200 ft from shore
Open Water
200+ ft from shore

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.

Mission Beach is the narrow sand peninsula between the Pacific Ocean and Mission Bay, 2 blocks wide and just under 2 miles long. A boardwalk runs the full length of the oceanfront, and Mission Boulevard runs the spine of the peninsula as the main north-south artery. Belmont Park sits at the center of the peninsula at 3146 Mission Boulevard. Its anchor attraction is the Giant Dipper, a wooden roller coaster that opened on this site in 1925, closed in 1976, and reopened in 1990 after a full restoration. At the south end, the peninsula tapers down to the harbor entrance jetty that separates Mission Bay from the open ocean.
