Warnings for today

None

West-facing rocky shoreline exposed to west through northwest energy at full force. Winter surf can close the site entirely. South swell wraps in moderately. Trade winds blocked by island mass but Kona winds hit directly. Rock-lined entry channel demands careful wave timing.
