HIGH SURF ADVISORY FOR EAST FACING SHORES

Our weather team will bring you any urgent weather alerts or updates as they occur. Check our breaking news section for the latest.

Swell Summary

Outlook through Wednesday December 19: The current northwest swell will peak late this morning into tonight just below advisory levels along north and west facing shores. A smaller northwest swell is then expected Thursday night through Saturday. A new and large northwest swell is then due in late in the day Saturday, with surf likely peaking at warning levels Saturday night and Sunday. Another even larger northwest swell is expected to build late Monday or Monday night, bringing another round of warning level surf to north and west facing shores Tuesday through the middle of next week.
Strong trade winds will keep advisory level surf in place along east facing shores through the remainder of the work week. Surf should drop below the advisory level Friday night, then continue to lower over the weekend as the trades diminish.
Surf heights are forecast heights of the face, or front, of waves. The surf forecast is based on the significant wave height, the average height of the one third largest waves, at the locations of the largest breakers. Some waves may be more than twice as high as the significant wave height. Expect to encounter rip currents in or near any surf zone.
