Warnings for today

  • High bacteria levels due to recent heavy rainfall

South-facing harbor protected by breakwater and Point San Luis. Excellent protection from west through northwest swell. Open to south through southeast energy, with south hitting at high exposure and south-southeast following at moderate levels. Generally calm unless a direct south swell runs. Watch for fishing lines.
