Large NW Swell to Peak Wednesday Afternoon

Hilo side: Surf is expected well overhead to possibly double overhead or more at the best breaks exposed to the rising swell.
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 northwest swell is fading and an overlapping northwest swell is forecasted to help increase surf heights on Wednesday afternoon to possibly double or even triple overhead at the best exposures. This swell is expected to peak Wednesday afternoon and hold through good size Thursday. Swell begins to fade late Thursday into Friday. The Kona side is heavily shadowed from these swells.
A series of swells are expected over the weekend and into next week as well. Next on tap an advisory level swell out of the northwest for Saturday / Sunday. Another northwest swell is expected late next week with another large northwest swell due for next weekend. All dependent on how the storms actually end up developing. Will keep an eye on it.
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.
