Swell Summary
A small short-period SE swell should provide a slight bump to favored S and SE facing exposures over the next few days. Another slight bump in S shore surf is possible early next week as a slightly larger SW swell advances toward the islands. East shore surf will hold near seasonal levels through Wednesday, then slowly lower Thursday through early next week. North shore surf will remain very small through the weekend followed by a bump early next week as a small medium-to-long period NW swell arrives.
