Sneaker waves return to the Bay Area

Just in time for your holiday stroll on the beach, sneaker waves are back.

It’s because of a weather system in the Pacific that will kick up swells by mid-week. That system is supposed to bring sunny skies and temperatures in the low 60s this holiday week, which is really enticing for a walk at the beach - especially if you're not traveling out of the area as health experts are urging.

This weather system is projected to send swells of 12 to 17 feet with sneaker waves of up to six feet.

Those are the ones that creep up and can pull you off the shore.

The National Weather Service said it’s too early to issue High Surf Warning, but they're keeping an eye on the Northwest-facing beaches like San Francisco’s Ocean Beach, San Mateo County’s Montara State Beach, Monterey County’s Marina State Beach and Monastery Beach in Carmel.

"Make sure that you’re with a friend or someone who knows that you’re going for a walk on a trail or going to the beach," said San Francisco Fire Department Lt. Jonathan Baxter. "Have a cell phone or some sort of communication device. Know where you are at. Know your location so that if something does happen and you do call 911, you’re able to say that’s where you’re at, which lessens the time for us to try to find you."

The expectation is waves will build all day on Wednesday, tapering off by Friday.
