Scuba diving in Los Angeles

Los Angeles hides a serious dive scene behind the beach culture. The Palos Verdes Peninsula and South Bay offer kelp-forest shore diving inside the city limits, and the boats out of L.A. harbors put Catalina and the northern Channel Islands — Anacapa and Santa Cruz Island — within a day trip. Local shops run the full ladder: try-dives and certification in the shore coves, guided kelp dives, and multi-site island charters.

The signature dives

Casino Point at Catalina is the region's showcase — a shore-entry marine reserve of kelp, Garibaldi, and summer giant black sea bass. Closer to home, Cabrillo Beach and White Point serve accessible reef and kelp on the Palos Verdes side, while Redondo Beach's submarine canyon is the after-work special: a sand slope that drops fast into deep water, famous for octopus, seahorses, and strange midwater visitors at night. Boat days at Anacapa and Santa Cruz Island bring the Channel Islands payoff — playful sea lion colonies, dense kelp, and passing dolphins on the crossing.

Conditions and season

Southern California diving runs year-round. Water spans the high 50s °F in winter to low 70s in late summer; a 7 mm suit is the local uniform, with drysuits common in winter. Visibility averages 15–30 ft on the mainland shore sites and jumps at the islands, where 40–60 ft days are routine — fall is the classic clear-water season. Surge and surf decide shore-diving days; the islands' lee sides stay diveable more often.

Good to know

Open Water certification covers most of the marquee sites, and L.A. is one of the cheapest, easiest places in the country to get certified with year-round classes. Island boats fill on summer weekends — book ahead. For shore dives, go at first light: parking, surf, and visibility are all better before the afternoon wind.
