.A large north-northwest medium period swell will build into the
Hawaiian Islands through Thursday increasing surf heights above
advisory thresholds along exposed north and west facing shores of
Niihau, Kauai, Oahu, Molokai, including north facing shores of
Maui and the Big Island. Surf heights will likely fall below
advisory thresholds by Thursday night as the swell energy
decreases.

the shoreline and in low-lying coastal areas. Coastal flooding is
possible around the daily peak tide, which will be during the
early morning hours.
