HIGH SURF ADVISORY FOR NORTH FACING SHORES

Swell Summary

Incoming large, medium period WNW (290-300) swell registered higher than anticipated at offshore NDBC Buoys 51101 and 51001 this afternoon prompting an upward revision to surf values for N and W facing shores of Kauai and Oahu and N facing shores of Maui as swell rapidly builds this evening. It is not out of the question that surf briefly touches the High Surf Warning threshold as it peaks overnight but uncertainty and borderline nature precludes an upgrade to a warning at this time. The surf forecast was likewise revised upward for W facing shores of Leeward Big Island where the 290-300 degree trajectory is favorable for building surf there by Monday morning. A High Surf Warning has been issued for these zones. A combination of moderate northwest and north swells will keep surf elevated through the week.

E facing shores remain tiny to small given the lack of trade winds but shorelines exposed to N swell energy may remain slightly elevated through Wednesday. Surf along S shores increases due to short period wind wave chop, mainly over the western islands associated with the passing front.
