Swell Holds Through Morning Before Fading
A High Surf Advisory is in effect for the Kona side of the island through 6:00 a.m. Thursday. The National Weather Service is calling for wave heights of 6 to 8 feet. Expect strong breaking waves, shore break and strong longshore and rip currents making swimming difficult and dangerous.
A Small Craft Advisory is posted for the Alenuihaha channel and leeward / south waters of the Big Island through 4:00 a.m. Thursday.

Hilo side: Wave heights from waist to head high are expected, biggest early in the day.
Kona side: Wave heights from waist to chest high early on with waves dropping in the afternoon and evening.
South: Wave heights of knee to waist high are expected from the south-southwest swell. Spots catching the Kona swell will get waist to shoulder high waves early on.
Our current shadowed west-northwest swell holds through Thursday morning before fading out. Short-period northwest shifting swell brings a reinforcement late Friday.
A northwest swell is expected for first few days of March. Will keep an eye on it.
Our current south swell is expected to slowly fade through the weekend. Another round is expected for the first week of March.
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.
