A large, long period north-northeast (010-030 deg) swell peaked early this morning and is expected to hold through the morning hours before declining through the end of the week. This swell will produce breaking waves at High Surf Warning levels across most north and east facing shores through this afternoon. Due to the direction of the large swell, exposed west facing shores of West Maui, western Molokai, and North Kohala on the Big Island will likely experience High Surf Advisory conditions. The north-northeast swell will gradually decline tonight at High Surf Advisory (HSA) level conditions through Wednesday before continuing to decline through Friday. In addition to this swell, a small pulse of overlapping west-northwest swell is expected through Wednesday. South facing shores will remain tiny today due to a small background southwest swell before flat wintertime surf resumes along south facing shores through the end of the week.
