From NWS Bay Area. This is a serious one, be safe. "Very large WNW swell to arrive Sunday and Monday. Cold and unforgiving Pacific waters accompanied with large waves are life threatening. Keep a safe distance from the ocean. Please don't become a statistic. Every year we lose many people to the cold waters of the Pacific. On Sunday long period waves will arrive along the coast. These high energy waves will run high up on area beaches. Sunday nite and Mon seas in excess of 20 ft will pound the coast."
