NWS Warns of Life‑Threatening Surf as 20‑Foot Waves Threaten West Coast

A long‑period northwest swell is driving dangerous surf along the California and Oregon coasts.

Overview

  • The South Central Oregon and Curry County coast are under a High Surf Advisory from Tuesday afternoon to early Wednesday with breaking waves of 21 to 24 feet.
  • Beach Hazards Statements cover the San Francisco to Big Sur coastline through Wednesday evening, with 12 to 17 foot breakers and the largest surf Tuesday night into Wednesday; some spots such as Mavericks could exceed 20 feet.
  • NWS offices for north and central Oregon and the south Washington coast warn of sneaker waves that can surge far up beaches and over jetties, creating a high risk of knockdowns and drownings.
  • Officials urge people to stay out of the water, keep off rocks and jetties, follow lifeguard guidance, and be especially cautious near high tide when run‑up is greatest.
  • Forecasters are monitoring a late‑week storm that could develop into an atmospheric river for the Bay Area and Central Coast, bringing rain, gusty winds, and localized flooding if it materializes.
