A small, short period, north northwest swell will fade through Wednesday. Another small northwest swell will fill in this weekend keeping surf slightly elevated along north and west facing shores.

East facing shores will maintain rough, short period windwaves generated from the breezy trade winds. As trades strengthen on Thursday through the weekend, surf will increase and become very rough and choppy, possibly nearing advisory levels.
