Dive Site Characteristics
Key Dive Site Facts
Dive Site Overview
A natural protection against ocean waves allows for diving opportunities throughout much of the year at this site. Beneath the surface, a sandy shoreline continues its gradual descent to a maximum depth of 50-60 feet (15-18 m).
Divers typically have two primary options: exploring the breakwater structure itself or venturing into the kelp forest. A kelp forest is shallow, often around 25 feet (7.6 m) max depth, while following the breakwater can lead to deeper sections. Beyond the main breakwater, the remains of a wooden barge are present, although precise navigation lines are not consistently reported.
Such wreckage provides an interesting point of exploration for those seeking artificial reef structures. A pump pipe also extends from the left side of the beach out to about 40 feet (12 m) of depth, often used as a navigation aid to metridium fields or to explore the kelp forests it intersects.
Both day and night dives are possible and frequently undertaken here, with night dives revealing different marine behaviors.

In contrast, February to March generally sees "Poor" dive scores due to increased wave heights, reaching averages of 2.7 m (8.9 ft) and 2.7 m (8.9 ft). Rain showers are minimal from June through October, with averages below 0.5 mm, whereas winter months like December experience more precipitation, around 3.0 mm.

Dive Experience & Conditions
Entering the water here is straightforward via a gently sloping sandy beach, though scattered rocks might be present depending on the tide. As divers move beyond the surf zone, visibility can be a factor, sometimes reported around 30 feet (9 m), but it also varies significantly. Nearer the shore, a kelp forest thrives, providing a vibrant habitat in shallower depths. Exploring along the breakwater's rocky contours offers options for deeper dives; while less life might be found at the very bottom, a 15-25 foot (4.5-7.6 m) range along the rocks is often rich with color and fish schools. Many divers appreciate the relatively protected conditions within the bay, though a substantial storm can still generate too much surf for comfortable diving.
Dive Difficulty & Safety Guidelines
Divers should be aware that sea lions occasionally occupy the beach for extended periods, making entry difficult or impossible. Monitoring local conditions and advisories before planning a dive is advisable. Parking enforcement is active, so ensure all parking fees are paid promptly. While generally protected, strong storms can impact surf conditions. For example, frequent use for dive training occurs, particularly in shallower areas, which can lead to higher diver density. Staying clear of training groups and maintaining good situational awareness is important for a smooth experience.
