Southern California's best dive encounters

David Mansfield1 comment

California is home to a highly diverse scenery above and below the waves. Northern California is covered in Giant Redwood forests and sweeping views of rugged terrain. Areas like Monterrey, Big Sur and Point Lobos State Natural Reserve provide divers an amazing view of a protected underwater realm. Meanwhile, the Central Coast of California is a gateway to the Channel Islands, where one of the largest Marine preserves in the country reside. Large animals like Orcas and the Grey Whale travel through the Channel Islands and grace bubble-makers with an unparalleled diving experience! As a traveler moves further south along the longest continuous state coastline in America, they'll find more beautiful water and enjoy many amazing areas that span from San Diego to Los Angeles. There is no doubt in any diver's mind that Southern California is a unique diving experience that must be jotted down on a bucket list and achieved! Whether you are looking for deep wrecks, kelp forests or swimming with some very large animals; you'll find it in SoCal. 

Millions of underwater inhabitants allow a diver to enjoy substantial viewings in a short amount of time and give divers plenty to talk about when they surface on the world-class beachheads to spend the rest of their day!

Here's a few of Southern California diver's favorite encounters! 

The "big'uns":

Giant Black Sea Bass

Meet Stereolepis gigas. Commonly known as the Giant Black Sea Bass (GSB), this behemoth can reach lengths of 7ft and weigh as much as 700lbs. This fish was sought after by fishermen and eventually found itself on an endangered species list; this prompted the California Department of Fish and Game to ban the fishing of the GSB in 1982. Slowly, but surely, the population is finding itself back in a common sighting for SoCal divers. The GSB find hunting grounds amongst shallow rocky reefs in California and tend to stay in their areas for some time. They utilize their giant maw to rapidly suck a prey into their mouths for feeding and they love to eat just about anything on the reef.  At the time of this writing, GSB's are currently hanging out at the Casino Point in Catalina and along the California coast at Heisler Park. They are a curious fish that will circle a diver and inspect them with their large eyes before moving along elsewhere along the reef. They are quite a treat to see on a dive!

California Sea Lions

Zalophus californianus is a carnivore that is very common along Southern California shorelines. They can live up to 30 years of age and weigh in at a whopping 800+ lbs upon full maturity. The California Sea Lion is the fastest of its family where it can reach speeds of 25 miles an hour. They are a social animal that many top-siders can enjoy as they lay about on docks, moorings, rocks and more. They are extremely smart hunters and can remain below the surface for 10 minutes. They are the ire of fishing boats, as sea lions will comfortably chill below a boat and snag fighting fish directly off reels for some lazy meals. The California Sea Lions are always fun to interact with but do require caution as they are a territorial wild animal. Divers in Southern California will travel to the Los Coronados Islands, La Jolla Cove, San Clemente's Seal Rock and Crescent Bay North's Seal Rock for a chance to encounter these animals. At Shaw's Cove, it is not uncommon to have a Sea Lion join a diver on a night dive. The resident there enjoys using a diver's lights to help hunt!

Pacific White-Sided Dolphin

Lagenorhynchus obliquidens is known as the Pacific White-Sided Dolphin and are protected by the Marine Mammal Protection Act. They are most noticeable in California waters because of their white stripes when they are cresting the surface of the water or viewed underneath the waves. They have a short beak and look very similar to a porpoise. The Pacific White-Sided Dolphin is highly sociable and is often viewed by boaters when the dolphins decide to surf the wakes of their boats. They are not shy when it comes to acrobatic maneuvers and often hunt in groups, which provide amazing views for observers. Surfers and divers alike will experience close encounters with a dolphin and there are many tales of watching dolphins surf the waves along the SoCal coastline. They are always fun to see under the water!

Grey Whale

Gray Whale

Eschrichtius robustus is an amazing thing to see in Southern California waters. This animal travels between Mexico and Alaska and provide whale watching tours a view unlike any other. Reaching 30-40 tons and 40-50 feet, a Gray Whale is a very noticeable passerby in Southern California. They are often covered in organisms and will provide onlookers with views of their tails (also known as flukes) and gigantic blowholes when they surface for air. Their two blowholes are positioned in such a way that when they exhale, their spout appears to be heart shaped. For Southern California divers, a gray whale is so large that it often creates a visual disturbance in the water when it passes. An animal that exceeds the length of full size school busses are wary of boats and will often travel or dive well away from them. On occasion, divers and sight-seers will get to enjoy a breaching whale or catch a glimpse of their beautiful flukes.

Sphyraena Argentea is a schooling fish that is often found in large packs throughout Southern California. It is a predatory fish that spans from the southern tip of Baja Mexico all the way up to coastal Washington state. They can grow to over 3ft long and weigh in at 15lbs. During winter, the Pacific Barracuda will move south to warmer hunting grounds before moving back into our favorite Southern California dives sites and becoming a treat to see while out in the water. These fish are aggressive hunters of smaller fish and are inquisitive by nature. They are attracted to shiny objects and will come close to a diver to take a look. Considering their sharp teeth, it is safer to maintain a distance and enjoy their beautiful views from afar!

Garibaldi

The Elusive Garibaldi

Hypsypops rubicundus can be easily identified by its bright orange coloration and inquisitive personality. Unlike other damselfish, who reside in warm tropical waters, Garibaldi can be found in temperate waters off the California coast from Monterey Bay down to the northern Baja coastline waters of Mexico. After over two decades of the Aquarium industry aggressively targeting the Garibaldi, California passed legislation in 1993 to protect these fabulous fish. In 1995, the Garibaldi was officially named the California State Marine Fish and are completely protected under state law from being removed from their habitats. The male Garibaldi is the housemaker of a mating pair. Not only does he select the nesting area, but he thoroughly prepares and maintains the area for the female to lay her eggs. Garibaldi are also very territorial and have meticulous boundaries of where one nest ends and the other begins. Be careful not to get too close! They have been known to chase divers away from their nesting areas. One of the authors may have been bitten by a combative garibaldi while photographing its nest. If you are diving in California, you can bet you will be able to see some of these vibrant fish!

Sheephead

California Sheephead

Semicossyphus pulcher are an incredibly long-lived fish species that inhabits the rocky reef and kelp beds of California. Its maximum known lifespan in the wild is 53 years! However, most Sheephead do not reach this age due to fishing demands. Males can be distinguished by their black and orange midsection, white chin, red eyes and prominent bulbous foreheads. Females are typically smaller than the males and are more of a dull pink in color with white undersides. These fish are sequentially hermaphroditic as adults. Which means they are all born female and can develop into a fully functioning male after reaching a certain maturity level and size. Environmental conditions and the ratio of males to females in their local populations spark this unidirectional sex change. As a male, this fish establishes a spawning territory during mating season and protects a group of females with which he breeds. If you’re diving in California, you’re likely to see at least one of these canine-toothed fish!

Moray Eel

The California Moray Eel

Gymnothorax mordax is a long, slim snakelike fish that is light to dark brown or green in color. Divers will typically find them tucked away in crevices during the day and prowling the reef for prey at night. The moray eel lacks pelvic fins, pectoral fins and gill covers. Most fish breathe by opening and closing their gill covers to force water over their gills. Since moray eels lack gill covers, they constantly open and close their mouths to push water over their gills, so it appears to be regularly gasping for breath (or waiting for the end of a bad joke). Scientists hypothesize that the California Moray’s off the Southern California Coast do not reproduce – possibly due to the cold-water temperatures. Moray’s living here are thought to hatch off the coast of Baja California and drift north as larvae.  A distinguishable feature of the moray eel is the “second set” of jaws located in the back of their throat, also known as pharyngeal jaws. When the eel’s front jaws bite into its prey, the pharyngeal jaws spring forward and latch onto the prey while dragging them deeper into the moray’s throat. Along with their two sets of jaws, moray’s also have dagger-like teeth that are full of bacteria. Even though a moray will not bite unless provoked, be sure to keep your hands to yourself and do not reach into moray territory crevices.

Octopus

Pacific Red Octopus

Octopus rubescens is known as the Pacific Red Octopus and can be found from Alaska to Baja California on the sandy or rocky bottoms of kelp forests to depths of 200m. This octopus is best identified by having three "eyelashes," or papillae, underneath its eyes and is typically red or brown in color. With arms around four times the length of its body, they typically hunt for marine invertebrates (crabs being a particular favorite) and fishes late into the night. Not only do octopuses have excellent sight, but they use each suction cup to taste, smell, and sense their surroundings. Be careful not to touch these guys! They have a powerful venom filled beak that they use to penetrate and poison their prey. Octopuses are gonochoric, where both male and female adults usually die shortly after spawning and brooding. They are considered to be the smartest invertebrate species, and potentially as intelligent as a house cat. However, not nearly as fluffy.

The "itty-bitty'uns":

Spanish Shawl

The Spanish Shawl

Flabellinopsis iodinea is a species of aeolid nudibranch that is so vibrant it will stop divers in their tracks! The body of the Spanish Shawl Nudibranch is translucent purple with intense orange cerata emerging from its back. Located on the top of the nudibranchs head are deep orange/red rhinophores that they use for navigation, finding mates and prey. They typically feed on tiny hydrozoan colonies that grow on kelp and will store the stinging cell from these hydrozoans and use it in their own cerata as a defense mechanism. Various species of nudibranchs often use this chemical sequestration process as they lack the physical protection of a shell. This nudibranch, like many other seal slugs, are hermaphroditic. Each nudibranch possesses both male and female reproductive organs on the right side of their heads. Self-fertilization is possible in many nudibranch species however it is extremely rare. On your next dive, slow down and keep your eyes out for these colorful beauties.

Mantis Shrimp

Hemisquilla californiensis can grow up to 12 inches long and can be found from silty shallow water to depths of 295ft from Point Conception to Panama. The California Mantis “Shrimp” is actually not a shrimp at all! True shrimp are Decapods that have ten legs with three pairs that have developed into mouthparts. Stomatopods, like the Mantis Shrimp, have only three walking legs while the rest are converted into feeding appendages. These tenacious shrimp have the ability to break glass up to one-quarter inch thick. For diver’s, finding this shrimp in the open is a treat! They are incredibly quick and prefer to burrow more than six feet long in soft, silty substrates. This resourceful shrimp likes its privacy and can conceal their burrows by placing shells and other debris over the openings. Similar to the American lobster, the Mantis Shrimp can produce distinct sounds by vibrating its carapace. Scientists have recorded that each individual animal produces a unique rumble sound, and that this acoustic activity is higher during dawn and dusk, times when they are feeding or guarding their burrows. Listen closely on your next night dive!

Catalina Goby

The Catalina Goby

Lythrypnus dalli is a small vibrant fish that almost never leaves direct contact with the rocky reef structures of the eastern Pacific Ocean. The Catalina Goby, or Bluebanded Goby, often hide near or under sea urchin spines (or the crevices that the sea urchins create), and do not like to stray far from these protective structures. This fish can be distinguished by their small stature, bright orange body coloration and electric blue striping. Another particularly interesting characteristic of this goby is its ability to rapidly change sex. Many marine fishes are able to change sex, but nearly all of these species are only able to change in one direction. As a bidirectional hermaphrodite, the Catalina Goby can change their sex back and forth within just a few days. This trait is eminent to these goby considering they rarely venture far from their territories, and this facilitates reproduction with nearby individuals.

Orange County Scuba Dive Sites

David Mansfield

There is no doubt that Orange County scuba diving surpasses the competition in terms of marine life encounters, quantity of sea life and unique exploratory dive sites. From San Diego to San Francisco, a diver can enjoy a wide range of scuba diving that provides clear, calm and cool waters. The abundance of dive sites, access to/from and the protection of those areas are on an entirely different level when it comes to Orange County scuba diving.

What makes Orange County so different? The topography offers unobstructed views of the ocean for those multi-million dollar homes that decorate the landscape of Southern California. This creates sweeping observation areas found throughout the region. These large hills continues downward towards the ocean and provide dramatic rock formations for divers to explore. For beach-goers, swimmers, paddle boarders and other aquatically focused folks; the public access areas to the Pacific Ocean are far greater than many other areas along the western coastline. Huntington Beach alone boasts a 9.5 mile state beach! The rocky formations found along the coastline continue well into the water; submerged and covered completely with ocean creatures. 

Diver in the ocean

As a visiting diver, many will notice that there are waves along the coastline. As divers move north towards Santa Barbara, Big Sur and Monterrey, they will experience large waves that have spent millions of years forming up California's beautiful views. These pose a challenge to beach divers throughout the region and many will find themselves traveling via boat to enjoy the dive sites found in these areas. As the coast moves south and east, one will find that coves and beaches become a little more protected. With the consistent swell and direction, many Southern California dive sites are often capable of successful scuba diving throughout the week. If you are in Orange County and looking to experience dive boats, you are more than welcome to explore Orange County Dive sites with boats like the Riviera Charters. This boat has operated in the Dana Point harbor for many years and has become the staple boat diving platform in Orange County. 

The beautiful rock formations are often accompanied by kelp. Kelp forests are prolific throughout Southern California and provide excellent protection for many animals. Diver's enjoy sweeping views as the kelp sways back and forth with sunlight rays poking through. It is amongst the most beautiful views found on earth. A diver can linger along the bottom and enjoy watching the fish travel through the area while watching the kelp forest. When you are on a dive site with kelp, it does not get much better!

Diver on the Riviera

There are naysayers when it comes to scuba diving in California. These protests can be narrowed down to three main issues: water temperature, wave action and visibility. 

The water temperatures range from 55°-75°F throughout the year. The average Southern California water temperature is 60°F. Usually, the cooler temps in winter will bring in high pressure systems that will keep the wave action low and provide us with great visibility. What most divers experience is the cooling effects of the outside temperatures which creates an undesirable effect to those of us that have an affinity for warmth! With the proper exposure protection, a diver can enjoy year-around scuba diving in Orange County. Whether finding an affordable drysuit or wearing a 7mm wetsuit, many divers enjoy scuba diving in Southern California year after year. 

The waves in Southern California do pose a risk to scuba divers and they are a very manageable risk. Scuba instructors throughout Orange County and all along the coast teach their divers at the lowest levels of learning how to enter and exit effectively from beaches.  These waves can become greater heights during tidal changes, wind shifts or other factors. If those conditions exceed your capabilities as a diver, it is a good idea to postpone your California diving activities or find another venue like a dive boat to enjoy your dives. Even a three or four foot wave is more than manageable to the majority of divers in Orange County. You'll find divers every single weekend at dive spots like Shaw's Cove as they safely enter and exit the water for their dives. If you are interested in learning how to beach dive, ask your instructor about the techniques! 

Visibility is affected on the Southern California coastline by wave action. The majority of dive sites have a sandy substrate; when the waves are up, the visibility is usually reduced. This does not make a dive site 'un-dive-able'; it simply means we change our perspective and travel further away from the beach to get better visibility. The average in Orange County is 10'-15'. The highs and lows are so drastic that there have been times when diving in Southern California felt like diving in the tropics with cooler waters. The clarity of the water is affected by numerous factors, but does provide an average that makes diving in California a year-around experience. 

Diver in the ocean

Overall, Orange County Scuba dive sites are excellent venues to enjoy whether the diver is visiting Southern California or is a resident of the area! If you are interested in exploring these areas, contact your local Southern California dive shop and get set up. You'll be very happy you did when you see how populated these areas are throughout Laguna Beach, Huntington Beach, Newport Beach and much more.

The #1 Dive Site in Orange County

David Mansfield

Orange County, California is home to many dive sites, but there is one site that dominates in frequency of divers, quality of diving, and accessibility. Utilizing these markers has led us to believe that Shaw's Cove is the #1 dive site in Orange County.

Located near Beach Cities Scuba, Shaw's Cove has spent over 80 years supporting the Southern California scuba lifestyle as well as visitors from all over the world! 

With that, we think that Shaw's is the #1 dive site in Orange County.

Here are the reasons why:

Frequency of Visits: There is no doubt that Shaw's Cove dominates the local dive community with frequency. On any given day, one will see a diver or two out in the parking areas prepping for a dive. On a weekend, it is not uncommon to see a hundred or more divers enjoying classes, diving for fun or just out exploring the Pacific ocean. You might see events at other dive sites throughout the year that draw the attention of divers; but at Shaw's Cove, you'll have consistent visits! 

Quality of Diving: We've conducted dives up and down the coast of California and much more. Of all those places, Shaw's Cove dominates in the "things to see" category. It is one of the only sites that has cut-outs that are expansive and enjoyable to explore. If you aren't in the cut-outs and caves, you can see a large kelp forest, reach deeper depths on the back side, visit Shelly of Shaw's (a little statue placed there in the early 2000's) or see if you can interact with Sea Lion's on the hunt. There is also an abundant amount of ocean life there. Lobsters are large and plentiful (this is a protected area under the MPA laws in Laguna Beach), every inch of the reef is covered in life and the population of fish is booming. You'll see the staple Garibaldi, Sheepshead, large schools of smelt and many other species here. Angel sharks, Bat Rays, Giant Black Sea Bass, Dolphins, Whales (yes, Whales), Blue sharks and other larger animals will pass by in search of food. This high percentage of things to do in Shaw's Cove make the quality of diving superior in Southern California dive sites. 

Shelly of Shaw's

Shelly of Shaw's: 

Not much is known about "Shelly of Shaw's." Apparently the Shelly has been a Shaw's Cove resident since the early 2000s. Shelly has moved a few times, and was vandalized at least once sometime around 2007. Every once in a while Shelly is mysteriously cleaned and cared for. Shelly currently sits roughly 10 meters east south east, from turnaround rock.

Accessibility: Shaw's Cove is an excellent location to conduct training dives for all recreational levels. It is in a semi-protected cove in terms of wave movement. When the swells are normal, Shaw's wave breaks will be lighter than other Southern California dive sites. When you might be at Wood's Cove and washed out, you might find Shaw's Cove to be an easier entry and exit! 

There is ample residential parking available at this dive site. It is also easily accessible from the Beach Cities Scuba location where many divers travel to and from on their shore dives. 

We know there are many dive sites in Southern California waters. If we were to rank them by popularity alone, it would be pretty easy to make the statement that the #1 dive site in Orange County is Shaw's Cove. Just ask any local, they more than likely got certified in Shaw's Cove , or they completed their first shore dives after certification at Shaw's. 

D.J. Mansfield is a PADI Course Director and Director of Operations for Beach Cities Scuba Centers. He's been in the fabric of the local dive community for 18 years and has hundreds of dives at Shaw's Cove alone. He can be reached at david.mansfield@beachcitiesscuba.com and is often found at the Cypress or Oceanside locations.
