A Small Craft Advisory has been issued by the National Weather Service for Big Island windward waters and the Alenuihaha channel through 6 a.m. Thursday for northeast winds of 10 to 20 knots and rough seas of 8 to 14 feet. This advisory may need to be extended as another large NW swell is expected to build late in the day.

Our current north-northwest swell is expected to peak Tuesday morning. An overlapping swell is forecasted to help increase surf heights on Wednesday afternoon at possibly double to triple overhead or more at the best exposures. This swell is expected to peak Wednesday / Thursday. The Kona side will be heavily shadowed from these swells.

Screen Shot 2014-12-08 at 8.47.54 PMA series of swells are expected over the weekend and into next week as well.

Super small trace amounts of swell expected out of the SPAC. Not much to get excited about. Late in the weekend or early next week we could see a fun little boost.

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.
