Swell Summary

N swell will gradually decline through tonight before a mid period WNW swell fills in tonight through Wednesday from a low to the NW. This swell will elevate surf to just below the HSA threshold but is expected to bring seas to 10 feet around Oahu and Kauai. This means that north shores should see relatively jumbled surf on Wednesday with the short to mid period energy mixing in. And a Small Craft Advisory (SCA) has been issued for the NW waters of Kauai and Oahu. A larger NW swell will then begin filling in by Wednesday night and peak on Thursday right around advisory levels. This swell could also briefly bring SCA level seas (10 feet) to the NW waters of Kauai. This swell will gradually fade out through the remainder of the week with small to moderate N and NW swells mixed in through the weekend.

E shores remain small except where NW-N swell energy wraps through the week. By next week, NE swell could elevate E shores and trade winds increase. S shores should see short period S swell due to persistent S-SW winds through at least the first half of the week, then decrease during the second half as the S-SW winds decrease.
