A High Surf Advisory has been issued by the National Weather Service for the Central Coast, in effect from 10:00am Saturday to midnight Sunday night. Seas will build to around 20 feet on Saturday, drop a couple of feet Saturday evening, then rise back to near 20 feet Sunday morning and to 20 to 25 feet Sunday afternoon before subsiding below 20 feet late Sunday night.
Large waves will have the ability to wash over jetties and run higher up on beaches than normal. They may also dislodge and move large logs and other debris on beaches that can easily catch people off guard and cause serious injury.
Due to the long period between these seas, dangerous sneaker waves, larger than those that precede or follow them, will intermittently arrive without any warning. You should stay well back from the surf this weekend.
