Generalized Statewide Coastal Waters Forecast for Hawaii
National Weather Service Honolulu HI
321 AM HST Sun Nov 30 2025

.Synopsis for Hawaiian coastal waters...
 A ridge of high pressure will dominate over or just north of the
Hawaiian Islands into early this week. A cold front will approach
the western islands on Wednesday, but may weaken to a trough and
retreat back westward before having much effect on the local
weather. By late this week into next weekend, strengthening
surface high pressure northeast of the islands will bring a
return of easterly trades. An extra large northwest swell will
peak this morning across the Hawaiian waters, then slowly decline
through Monday. This swell will bring seas above Small Craft
Advisory levels for exposed waters.
