Light Winds & Large Surf Today
A Marine Weather Statement has been issued by the National Weather Service for a very large west-northwest swell. The Weather Service in Honolulu says a rapidly building swell will arrive tonight and remain elevated into Thursday. They are warning of strong harbor surges and large breaking waves at harbor entrances exposed to the swell. One location that could expect such conditions is Honokohau harbor.
A High Surf Warning has been issued for the west side of the Big Island. The warning goes into effect this evening at 6:00 p.m. and is posted through Thursday at 6:00 p.m. Wave heights of 15 to 20 foot faces are expected. Expect ocean water occasionally sweeping across portions of beaches, very strong breaking waves and strong longshore and rip currents. Breaking waves may occasionally impact harbors making navigating the harbor channel difficult. Large breaking surf, significant shore break and dangerous currents will make entering the water very hazardous. Boaters should be aware of an increased number of surfers in the water.
A Small Craft Advisory has been issued for all island waters from 6:00 p.m. tonight through 6:00 p.m. Thursday for southwest winds from 10 to 20 knots and rough seas of 8 to 18 feet.
