Reading today's ocean conditions…
Ocean Safe scores conditions from public NOAA and Open-Meteo data. We don't certify any beach as safe or unsafe, and this is a modeled estimate, not an official forecast. Always check posted signs, county lifeguards, and weather.gov, and decide for yourself. How we score beaches.
⚠ Not a swimming beach
Remote olivine-sand cove inside a collapsed cinder cone with no lifeguard, no shade, and no rescue. The bay opens to the open South-Point swell window; strong wrap-around currents are hard to spot, waves can break directly onto the steep cobble shore, and the only exit is a ~2.5-mi cliff-edge hike. Visitor drowning/distress reports exist. Treat as a viewpoint, not a swim beach — if you enter at all, only on a genuinely flat day, never alone, and stay close to shore.
