Warnings for today

  • Strong surge expected

Exposed pinnacle off Santa Barbara Island's northern tip, taking the full brunt of dominant northwest and west-northwest swell. Northerly energy from all directions arrives at high strength. Westerly swell impacts the site significantly, while southwest wrap-around is moderate. Santa Barbara Island's mass provides good protection from south and southeast swell. This open water location means conditions closely follow the prevailing Pacific swell, with strong currents common around the rock's base.
