Large NNW Swell Builds Today
A Small Craft Advisory is posted for all Big Island channels and windward waters through 6 p.m. Wednesday.
**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 expected head high to start with wave heights quickly building in the afternoon up to overhead or even double overhead by sunset.
Kona side: Wave heights waist/shoulder/head high are expected today. The best breaks could get overhead or more on the sets.
South: Wave heights are expected waist/head high today. Best breaks open to the building swell could get up to overhead on the sets by sunset.
Another, more westerly, swell is expected on the heels of this one for the end of the work week. This energy should build Thursday, peak Friday and ease through the weekend.
Our current south-southwest is expected to peak Tuesday and begin to gradually ease on Wednesday.
Next week another pulse of south-southwest is expected. Will keep an eye on it.
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.
