Cortes Bank is surfing's most remote big wave venue—an underwater mountain rising from the seafloor 100 miles off the San Diego coast.

Best Conditions

Swell Direction: The ideal swell direction is W (281°), with workable conditions from W to WNW (270°–292°). Swells outside this window will either miss the break or produce disorganized waves.

Swell Size: Cortes Bank needs a minimum of 18.3m / 60ft to start working and handles swells up to 22.9m / 75ft before conditions deteriorate. When it maxes out, expect powerful, heavy-water conditions.

Swell Period: Look for a swell period of at least 18 seconds, with 20 seconds being the sweet spot. Longer periods deliver more organized, powerful waves with better shape.

Wind: True offshore here blows from the E (90°). The full offshore range spans NE to SE (45°–135°). Glassy conditions under 4km/h from any direction also produce excellent surf. Plan for early morning dawn patrol sessions.

Tide: This spot works best at low tide.
