Alerts (as of 1:00 a.m.)
A Small Craft Advisory is posted for our usual windiest Hawaii County waters through 6 p.m. Friday.
**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 are forecast from head high to overhead today for the best breaks.
Kona side: Wave heights are expected to be pretty flat today.
South: Wave heights are expected to be pretty flat today. Spots catching the wrap from our fading swell will be bigger.
Our current northwest swell is forecast to continue fading on the Big Island and should be down to traces by Thursday. Another swell is expected to build Friday and hold into Saturday before fading out. Another modest dose of north-northeast is forecast for the 20th through 22nd.
Nothing significant is expected out of the SPAC with minimal leftovers expected this week.
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.
