    Weather Alerts
    Coastal Flood Advisory - 4:33pm Fri Aug 7 2026

    ...COASTAL FLOOD ADVISORY REMAINS IN EFFECT UNTIL 2 AM PDT THURSDAY...

    WHAT: Up to 1.6 ft of inundation above ground level is
    possible in low-lying areas near shorelines and tidal
    waterways.

    WHERE: Bayshore locations along the San Francisco Bay, San
    Pablo Bay, and Monterey Bay.

    WHEN: From 5 PM Friday to 2 AM PDT Thursday.

    IMPACTS: Flooding of lots, parks, and roads with only
    isolated road closures expected.

    ADDITIONAL DETAILS: At the San Francisco tidal gauge, high
    tide is expected to be 1.0 ft above normal (6.84 ft MLLW) at
    6:55 PM Friday 8/7, 1.4 ft above normal (7.25 ft MLLW) at 8:00
    PM Saturday 8/8, 1.6 ft above normal (7.44 ft MLLW) at 9:02 PM
    Sunday 8/9, 1.6 ft above normal (7.46 ft MLLW) at 10:01 PM
    Monday 8/10, 1.6 ft above normal (7.44 ft MLLW) at 10:57 PM
    Tuesday 8/11, and 1.3 ft above normal (7.14 ft MLLW) at 11:49
    PM Wednesday 8/12. These predictions include both astronomical
    tides and roughly 3-6 inches of additional water mainly from a
    combination of thermal expansion and accumulated sea level
    rise since the tidal datum was established (1983-2001). High
    tide varies up to 90 minutes earlier or later along the
    Pacific Coast and through the San Francisco Bay, respectively.

    PRECAUTIONARY / PREPAREDNESS ACTIONS:

    High tides may result in flooding along coastal trails, cut off
    access to some low-lying coastal areas and beaches, and bring
    water and waves farther up the beach than typical. If travel is
    required, allow extra time as some roads may be closed. Do not
    drive, bike, or walk around barricades or through water of unknown
    depth. Take the necessary actions to protect flood-prone
    property.
