    Beach Hazards Statement issued November 9 at 8:12PM PST until November 9 at 10:00PM PST by NWS San Francisco CA

    From: 2026/11/09, 20:12
    To: 2026/11/09, 22:00

    * WHAT...For the Coastal Flood Advisory, up to 1.6 ft of inundation above ground level is possible in low-lying areas near shorelines and tidal waterways. For the Beach Hazards Statement, an increased risk for sneaker waves and strong rip currents with breaking waves of 12 to 16 ft expected. * WHERE...Pacific Coast. * WHEN...For the Coastal Flood Advisory, until noon PST Tuesday. For the Beach Hazards Statement, until 10 PM PST this evening. * IMPACTS...High tides will result in flooding of low-lying infrastructure, isolated road closures, and coastal erosion. Rising tides will bring water and waves farther up the beach than normal, restricting escape from beaches and coastal areas. Waves can sweep across the shoreline without warning, pulling people into the sea from beaches, jetties, and rocks. * ADDITIONAL DETAILS...At the San Francisco tide gauge, high tide is expected to be: 1.5 ft above normal (7.3 ft MLLW) at 11:04 AM Tuesday 11/10. These predictions include up to 1.2 ft of surge that will enhance the astronomical tide and flooding threat. High tide varies up to 90 minutes earlier or later along the Pacific Coast and through the San Francisco Bay, respectively.

    • If travel is required, allow extra time as some roads may be closed. Do not drive around barricades or through water of unknown depth. Take the necessary actions to protect flood-prone property. Stay off of jetties, piers, rocks, and other waterside infrastructure. Remain out of the water to avoid hazardous surf and NEVER turn your back on the ocean. Monitor local weather, surf and tide forecasts at www.weather.gov/mtr.
