Swell Summary
A series of small, medium period south (170-190 degree) swells is expected throughout the rest of this week, with surf near the summertime average through around Saturday along south-facing shores. The largest of these south swells looks to arrive Thursday into Friday. Surf heights should decrease Sunday into early next week as these swells fade. Another small, long period south swell could arrive by the middle of next week.
Choppy conditions will continue for east-facing shores through the forecast period due to the persistent fresh trades. Surf along north facing shores will remain nearly flat through the next week.
