Diving in California is diverse and spectacular, but if one feature defines the state’s underwater experience it’s the towering kelp forests that rival California’s iconic redwood trees.
This marine algae can live for 20 years, reach lengths of 45 metres/150 feet and grow 60 cm/two feet a day. Few dive sites compare to descending through enormous fronds that stretch from the seafloor to a lush surface canopy. Sunbeams filter through the kelp, and marine life thrives in every direction.
In Northern California, sea otters rest on the surface, vivid orange Garibaldi show little fear and bat rays glide along sandy bottoms. Scuba diving in California delivers a rewarding experience for every marine enthusiast.
Diving in California is possible year-round, with the understanding that winter months (December–February) are cooler than summer months (June–August). Average water temperatures reach 68°F (20°C) in summer, while winter conditions range between 57–59°F (14–15°C). It’s always recommended to check with a local dive shop in advance to confirm which California dive sites are accessible during your visit.
With a wide variety of dive sites, this region suits all diving experience levels. Underwater visibility commonly ranges between 10–20 metres.
For divers interested in large marine life such as gray whales, December–April marks their primary migration period along the California coast.
SFO (San Francisco International) and LAX (Los Angeles International) handle the majority of international flights to California. OAK (Oakland International), located near San Francisco, is often a more affordable alternative.
Domestic flights to California are served by BUR (Burbank), LGB (Long Beach), SNA (Orange County) and SAN (San Diego).
