Alerts (as of 1:00 a.m.)

High Surf Advisory: North shores of Big Island through 6 p.m. Monday.

Small Craft Advisory: Until 6 p.m. Monday for 10 to 20 knots with higher gusts.

Marine Weather Statement: The current north swell has peaked overnight and is trending down Monday. This swell could still produce moderate surges in all north facing harbors like Hilo Harbor. Large breaking waves near channel and harbor entrances mean mariners need to exercise caution when entering or leaving port and when mooring or launching vessels.

Check our breaking news section for any urgent weather alerts or updates to the weather alerts listed above.
