Although this image looks tempting, NorCal surfers/sailors, the National Weather Service issued a high surf advisory today for Bay Area beaches. The advisory goes into effect from 10 a.m. to to 4 a.m. Saturday.

Yesterday at Ocean Beach, 25-foot -- 25-foot!! -- waves came crashing down. BCN/CBS 5 reports." What's more, a northwest swell of 14 to 18 feet due to arrive along the Central California coast by Friday morning combined with local gale force winds will make the seas choppy, according to the weather service."

So, you know, don't go in the water today or tomorrow.

The advisory affects San Francisco, Santa Cruz, San Mateo, Marin, and Monterey counties.
