Mix of Swells Lingers, New Swells Sunday
A Small Craft Advisory is posted for the ʻAlenuihāhā channel as well as waters to the south and west of the Big Island. The advisory is through 6:00 p.m. Saturday for northeast winds from 20 to 25 knots and rough seas up to 11 feet. Inexperienced mariners should avoid navigating in these conditions.
**Click directly on the images below to make them larger. Charts include: Big Island projected winds, tides, swell direction & period and expected wave heights.**
Hilo side: Wave heights from waist to head high are expected, the best breaks could be slightly overhead on the sets.
Kona side: Wave heights from ankle to thigh high are expected. The best spots could get waist high waves on the sets.
South: Wave heights of knee to waist high are expected. Standout spots could get up to chest high on the sets.
A mix of short to mid period north-northwest swell energy, shadowed west-northwest and northeast trade swell is expected to linger the next few days for the northeast coast. Onshore winds will make conditions messy.
Looking farther out, a northwest swell generated by a storm off of Japan is expected to bring a shot of surf energy Saturday, peaking Sunday. Another developing storm north of the state could bring a pulse late on Sunday through about Tuesday. Another storm expected to develop near the Aleutians could bring a solid swell around the 13th. Will keep an eye on it.
South shores are expected to go quiet from Friday through the first part of next week. We may get some energy headed our way around the 13th.
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.
