Coastal Waters Forecast
National Weather Service Honolulu HI
321 PM HST Thu Aug 20 2026

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

PHZ100-211415-
321 PM HST Thu Aug 20 2026

.Synopsis for Hawaiian coastal waters...
A trough just northeast of the islands will track northwestward
across the offshore waters, leading to a period of light and
variable winds for most waters through tonight. By late Friday,
moderate to locally fresh trades will begin to build back into the
region as the trough exits to the northwest, high pressure drifts
southward closer to the island chain, and Tropical Depression
Two-C nears the state from the southeast. The forecast for this
weekend will depend on the track of this tropical cyclone, but
overall the trade winds are expected to strengthen.
