Swell Summary
A small, short-period north-northeast swell will build today then decline Friday. Some of this swell will wrap into exposed eastern shores, but otherwise, east shore surf will be below May average as the nearby trade wind flow will be weaker than normal into Saturday. A small northwest swell is possible early next week, while returning trade winds will increase east shore surf.
A mix of small southwest and south-southeast swell may produce inconsistent surf near seasonal average through Friday. Expect south shore surf to be at summertime background heights this weekend through the middle of next week.
