Sneaker Waves and Strong Rip Currents Threaten Bay Area this Week

The National Weather Service has issued a beach hazards statement for parts of the Northern California coast, including Northern Monterey Bay, Big Sur, and the San Francisco coastline. The warning is in effect until Wednesday at 10 p.m.

The concern comes from a powerful west swell pushing toward the coast. This type of ocean swell can create sneaker waves—sudden, unusually large waves that surge much farther up the beach than normal. These waves can knock people off their feet, sweep them off rocks or jetties, and catch visitors off guard during long stretches of calm ocean.

Forecasters say waves will reach 10 to 14 feet, with quiet periods of 10 to 20 minutes between the largest sets. Those calm moments are when people tend to let their guard down.

Alongside the surf hazards, the NWS warns of high tides running above normal through the week. These higher tides could cause minor coastal flooding, especially in low-lying areas or near roads that sit close to the shoreline. Tides will peak each morning, with some running more than a foot above typical levels.

The NWS urges visitors to use extreme caution:

• Stay far back from the water and off rocks or jetties
• Never turn your back on the ocean
• Avoid driving through flooded areas or around road closures
• Keep children and pets well away from the surf zone

Conditions may look calm at times, but strong rip currents and sudden waves make the shoreline dangerous through midweek.
