Our current northwest swell is gradually weakening another northwest swell is expected to build late Tuesday into Wednesday. Knee to waist high sets are expected with this swell for the Kona side. Additional northwest pulses are also on the radar later in the week and through the weekend.
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.
