Issued at 334 PM HST Fri Apr 24 2026 A ridge north of the islands will maintain a moderate to locally breezy trade wind pattern into the weekend. VFR conditions are expected to prevail across the islands. Brief MVFR conditions are possible, primarily in windward areas due to isolated showers.

A small medium period NW swell should fill in tonight into Saturday, which should provide a modest increase along north and west facing shores. A slightly larger NW swell will fill in late Saturday and peak on Sunday. A developing hurricane-force low this weekend near the Aleutian Islands should send a moderate northwest swell towards the middle of next week.
Buoy 51000 NE of Oahu showed modest increase of short-period energy from the NE this morning associated with a small fetch of strong winds few hundred miles NE of the state. This should provide a short- lived increase along east facing shores tonight into Saturday. Otherwise, below average surf is expected along eastern exposures into next week due to the lack of any strong trade wind activity over and upstream of the state.
Small background energy from the west will continue to linger through Saturday and fade out late this weekend. A small southwest bump from the Tasman Sea that passed across the American Samoa 51209 buoy Wednesday is expected to arrive tomorrow.
