Watch Out for the Waves!
Already elevated surf will build even higher Friday afternoon and evening with breaker heights around 20 feet along the Northwest California coastline. After a brief period of lower surf late Saturday, surf will again build late Sunday and into Monday as very large, long period westerly swell arrives. Breaker heights during this time period will approach 30 feet, and a High Surf Advisory or High Surf Warning may be required. Large waves will lead to increased run-up on beaches with waves topping and washing over large rocks and jetties. These large waves will be capable of sweeping people into the frigid and turbulent ocean waters. Beachgoers need to stay farther back from the surf and off of jetties or rocks, and mariners should use extreme caution when operating near the surf zone.
