High Surf Warning Continues as Several Swells Build Today
A High Surf Warning is posted for east facing shores of the Big Island through 6 p.m. Thursday with wave heights rising to 12 to 18 foot faces in some spots Tuesday. 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 is posted for Big Island windward and southeastern waters as well as Alenuihaha channel through 6 p.m. Thursday for rough seas up to 12 feet. Inexperienced mariners should avoid navigating in these conditions.

Hurricane Kilo crossed into the west pacific and is therefore now a typhoon. Kilo is expected to generate fun westerly swell to the islands starting Wednesday and peaking Thursday into Friday, then holding through the weekend.
Hurricane Jimena should deliver a solid shot of east-southeast shifting east swell to the islands from Wednesday through the weekend.
Long-period south-southwest swell is expected to build through Wednesday and Thursday, peak Friday and hold through the weekend.
Keep in mind, surf heights are measured on the face of the wave from trough to crest. Heights vary from beach to beach, and at the same beach, from break to break.
