Big Island Surf Forecast, Wednesday, January 7, 2015
Hilo side: Surf heights are expected to build and peak in the afternoon at well overhead to double overhead. The best breaks open to the swell could reach triple overhead late in the day.
Kona side: Surf heights are forecasted from knee to about shoulder high. Largest in the afternoon.
South: ESE trade swell brings knee to shoulder high waves. Otherwise, southerly spots are below waist high.
Our current west-northwest is expected to hold through Thursday. A larger north-northwest (330-360) swell is expected to fill in and peak Wednesday up to double (maybe triple) overhead at the best exposures. This swell is expected to fade Thursday into Friday.
Pending development of storms, we may get another west-northwest over the weekend with another shot of energy expected early next week as well.
Nothing of note out of the SPAC to get excited about.
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.
