San Pedro Wrecks covers a cluster of sites in the Pacific Ocean off Southern California, accessible by both shore and boat from San Pedro, Long Beach, and Rancho Palos Verdes. The area spans everything from shallow beginner-friendly reef and kelp forest dives to advanced and technical wreck dives, including the UB-88, a First World War German U-boat sitting at depth and requiring trimix or rebreather certification. Visibility is variable, generally better in summer and autumn when water temperatures rise toward nineteen or twenty degrees Celsius from their cooler winter baseline around fourteen degrees. California sea lions, leopard sharks, giant Pacific octopus, and garibaldi are among the recorded species across the six sites.
