Lineup Insights
The Wave
Peak windows are long-period N-NNE groundswells with lighter S-SSW winds (south-southwest offshore).
Mid-to-high rising tides usually clean the takeoffs and closeouts tighten on low slack.
Lineup Guide
The lineup sits tight to rocky reef and a river outflow - expect sea urchins, shallow rock paddles, strong rip sets near the mouth and local traffic on peak days.
Respect the local peak and watch for submerged hazards during lower tidal stages.
