Dangerous Beach Conditions Forecast Along Sonoma, Bay Area Coast

Sneaker waves will arrive irregularly during otherwise deceptively calmer seas, the National Weather Service said.

SONOMA COUNTY, CA — A beach hazards statement warning of dangerous conditions along the Bay Area coastline, from Sonoma County to Big Sur, went into effect Wednesday morning and was expected to continue through 4 p.m. Thursday, according to the National Weather Service San Francisco Bay Area.

"A high to extreme risk of sneaker waves will exist during this timeframe," forecasters said. "The largest energetic sneaker waves will arrive irregularly every few minutes to as infrequently as once every 30 minutes during otherwise deceptively calmer seas and consequently may catch those on coastal jetties, rocks, piers, or shorelines off-guard and may injure them or knock them into the cold, turbulent ocean."

In addition, strong rip currents will accompany the energetic wave train, particularly at west-northwest facing beaches.

The weather service advises:

  • Keep your eyes on children and pets; and
  • Never turn your back to the ocean.
