Screen Shot 2015-04-21 at 6.10.41 PMOur current northwest is expected to fade out today into Thursday. A small boost out of the west-northwest is expected to build Friday for Saturday. Another boost is expected early next week out of the northwest.

Combo of southwest and south-southwest swells expected to peak today, hold through Thursday and fade out Friday into the weekend. Next week is looking pretty quite out of the southern hemisphere.

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.
