Alerts (as of 1:00 a.m.)
A Small Craft Advisory is posted for the ʻAlenuihāhā channel and Big Island southwest waters through 6 a.m. Sunday.
**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 for spots exposed to the swell are expected to be shoulder/head high today. Spots without direct exposure to the swell will be smaller.
Kona side: Wave heights are expected to be waist/shoulder high today. The best breaks could get up to head high from time to time on the sets.
South: Wave heights are expected to be waist/head high today. The best breaks could get up to slightly overhead on the sets.
A northwest reinforcement is expected to move in Friday and Saturday up to thigh high at the best exposures. Another northwest pulse is possible April 27th and again for the 30th.
A new south-southwest peaks Friday up to at least waist/shoulder high. Another smaller south-southwest is expected for the weekend but not expected to increase wave heights over what the fading swell will already be providing.
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.
