Visibility Breakdown
Visibility by position
Each zone is how deep underwater you were when you saw that visibility, not how deep the water was. Anything you saw from the surface, snorkeling or looking down from a boat, goes in the Surface Zone.
Surface Zone: Visibility seen by a diver between the surface and 30 ft down. Every reading taken from the surface, snorkeling or looking down from a boat, goes here. Haze can sit in this top layer.
Mid Zone: Visibility seen by a diver between 30 and 60 ft down.
Deep Zone: Visibility seen by a diver 60 ft down or deeper. Less light reaches this deep, so the water can look darker even when it is clear.

About Coronado Islands
Islas Los Coronados are a chain of four granitic fault-block islands strung about 8 kilometers northwest to southeast in Mexican water, roughly 15 miles south of San Diego and about 7 miles south of the border. From north to south the group runs Coronado Norte, the small pyramid of Middle Rock, Coronado Centro, and Coronado Sur, the largest of the four at about 2 miles long and rising to 205 meters at its southern summit. The rock is granite and metamorphic basement, part of the Peninsular Ranges Batholith, not the volcanic material sometimes assumed offshore. Steep escarpments drop straight from the cliffs into a rocky bottom, giant kelp fringes the shores, and within a short distance to the west the sea floor plunges past 1,100 meters. A charter out of San Diego reaches the islands in about an hour.
