Dangerously Large Surf to Hit San Francisco Bay Area Coast: Breaking Waves 25 to 35 Feet, Sets up to 50 Feet
The National Weather Service's San Francisco Bay Area office issued a High Surf Warning on November 12: from 6 p.m. Friday, November 13, to 4 a.m. Sunday, November 15, dangerously large breaking waves of 25 to 35 feet are expected along the Pacific coast of the San Francisco Bay Area and Monterey Bay, with occasional sets of 40 to 50 feet at favored breakpoints.
The warning covers the Coastal North Bay including Point Reyes National Seashore, the San Francisco Peninsula Coast and Northern Monterey Bay, as well as the San Francisco coast and the Southern Monterey Bay and Big Sur Coast.
Ahead of the warning, a Beach Hazards Statement remains in effect through Friday afternoon, with an increased risk of sneaker waves and strong rip currents and breaking waves of 15 to 20 feet. Coastal Flood Advisories are also in effect: up to 1.5 feet of inundation above ground level is possible in low-lying areas near shorelines and tidal waterways around high tide on Friday; at the San Francisco tide gauge, the high tide at 12:49 p.m. Friday is expected to reach 7.3 feet MLLW, 1.5 feet above normal, including up to 1.8 feet of surge. From midnight Friday night to 6 p.m. Saturday, large breaking waves will run up beaches and crash over seawalls, inundating adjacent low-lying infrastructure.
The Weather Service says the dangerously large breaking waves can overpower swimmers, pulling people into the sea from beaches, jetties and rocks, resulting in significant physical injury and increasing the risk of drowning, and that waves can sweep across the shoreline without warning. High tides will also bring flooding of low-lying infrastructure, isolated road closures and coastal erosion. Everyone should remain out of the water and stay off jetties, piers and rocks, and never turn their back on the ocean; drivers should not go around barricades or through water of unknown depth.
