Our current west-northwest swell is expected to start easing Friday but a reinforcement is right behind it. The new swell is expected to build Friday and peak late that day, then hold into Saturday morning and ease late Saturday into Sunday. Another swell is expected on the 25th as well.
Saturday and Saturday night a High Surf Advisory is forecast for east facing shores.
A small southwest swell is forecast for the 22nd through the 24th.
Keep in mind, surf heights are measured on the face of the wave from trough to crest. Heights vary from beach to beach, and at the same beach, from break to break.
