    Weather Alerts
    High Surf Advisory - 8:19pm Sun Jul 19 2026

    ...HIGH SURF ADVISORY REMAINS IN EFFECT UNTIL 11 PM PDT TUESDAY...

    WHAT: Large breaking waves of 4 to 7 feet with sets up to 8
    feet at south or southwest facing beaches.

    WHERE: San Diego County Coastal Areas and Orange County
    Coastal Areas.

    WHEN: Until 11 PM PDT Tuesday.

    IMPACTS: Dangerous swimming and surfing conditions and
    localized beach erosion.

    ADDITIONAL DETAILS: South swell of 4 to 5 feet with a period of
    12-13 seconds generating high surf, primarily for south- facing
    beaches. High risk of rip currents exists with high surf and
    strong longshore currents are expected on west-facing beaches.
    High tides will generally be at or below 5.5 feet, but localized
    areas of beach erosion and minor tidal overflow may occur with
    the high surf during high tides. Swell and surf will decrease
    late Tuesday into Wednesday.

    PRECAUTIONARY / PREPAREDNESS ACTIONS:

    Inexperienced swimmers should remain out of the water due to
    dangerous surf conditions.
