Coastal Waters Forecast
National Weather Service Honolulu HI
309 AM HST Wed Aug 10 2022

Hawaiian coastal waters within 40 nautical miles including the
Hawaiian Islands Humpback Whale National Marine Sanctuary.

PHZ100-110145-
309 AM HST Wed Aug 10 2022

.Synopsis for Hawaiian coastal waters...
The islands are sandwiched between a strong surface high pressure
system located far north-northeast of the area, and an elongated
surface trough located far to the south. This will produce
locally strong trade winds and slightly elevated, rough seas
during the next couple of days. As the surface trough shifts
southwest of the area, expect a more typical trade wind pattern
from Friday into this weekend.
