NW Swell Holds Through the Day
Alerts (as of 1:00 a.m.)
A Small Craft Advisory is in effect through 6 a.m. Thursday for Big Island windward waters and the Alenuihaha channel.
**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 high today or more. Smaller for spots without direct exposure to the swell.
Kona side: Wave heights are expected to be knee/thigh high today.
South: Wave heights are expected to be waist high or less today. Spots with exposure to the wind generated waves could be bigger.
Our current northwest swell is holding steady through Thursday. Friday the swell should start to ease and shift. Another swell is possible around April 9th. The Big Island will again be heavily shadowed from this swell.
Not much expected out of the SPAC anytime soon. Minimal southerly swells will trickle in over the next several days.
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.
