Screen Shot 2015-09-21 at 10.17.48 PMOur reinforcing SSW swell is expected to hold Tuesday morning before starting to slowly fade through the day and into the week. Small scale south-southwest swells are expected through the end of the month but nothing super noteable.

Trade winds will continue to generate short-period choppy surf at moderate levels along east facing shores through the weekend. Other than that, there is nothing of note out of the NPAC.

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.
