Swell Summary
Tiny long period energy out of the S is noted on the Barber's Point PacIOOS Buoy this afternoon. This energy represents the initial forerunners of a rather small (about 1 foot), long period swell that will maintain elevated surf for S shores through mid- week. This is separate from the more substantial short to medium period fresh swell emanating from Nolo which has prompted today's High Surf Advisories (HSA) for S shores and W facing shores of the Big Island. Uncertainty related to the size of Nolo's swell coupled with its slow forward motion Tuesday night through Wednesday will be a theme in the forecast for the next couple of days. The latest observations support expiring the HSA for all but Kauai and Niihau where the bulk of the SW energy is directed. For Kauai/Niihau in particular, high surf may linger into midweek conditional on the exact size of Nolo's swell.
Surf along E shores slowly declines as trades veer to SE and diminish then return as light to moderate easterlies this weekend. A small, long period S swell originating east of New Zealand is poised to arrive early next week in maintenance of elevated surf along S facing shores.
For N facing shores, the existing small medium period swell fades through Wednesday. Multiple rounds of tiny swell originating out of the NW quadrant will reach N and select W facing exposures next week as the storm track in the vicinity of the Aleutian Islands becomes increasingly active.
