Coastal Waters Forecast
National Weather Service Honolulu HI
327 PM HST Wed Aug 19 2026

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

PHZ100-201415-
327 PM HST Wed Aug 19 2026

.Synopsis for Hawaiian coastal waters...
High pressure to the far northeast will gradually weaken over
the next couple of days. As a trough to the east of the islands
passes on a westward track across the region, moderate trades
will become light and variable by Thursday. By late Friday,
moderate to locally fresh trades will begin to build back into the
region as the high drifts southward closer to the island chain
and an area being watched closely for potential tropical
development nears the state from the southeast. The forecast for
this weekend will depend on how this next potential tropical
cyclone evolves.
