Cortes Bank

100mi off San Diego, USA (CA)
⚠️Shallow🪸Sharp reef

Cortes Bank is surfing's most remote big wave venue—an underwater mountain rising from the seafloor 100 miles off the San Diego coast. When massive Pacific storms generate huge W-NW swells, waves break on the shallow reef at heights that rival anything on Earth: 70-100 foot faces have been documented. Getting there requires a major boat expedition and perfect weather windows. The wave breaks maybe 3 days per year. Cortes Bank represents big wave surfing at its most logistically extreme and potentially largest scale.
