XL Swell Expected for Northerly Exposures
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.

Hilo side: Surf is expected well overhead to possibly double overhead or more at the best breaks.
Kona side: Surf is expected knee to shoulder high for the best exposures.
South: Southeast shores open to the trade swell could see waves knee to shoulder high, though slightly choppy conditions are expected. Minimal surf out of the southern hemisphere – knee high or less.
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.
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.
