Swell Summary
Small surf along north facing shores will hold through today before easing Saturday as the current north- northeast swell fades. A larger, mid- period north- northwest swell is expected to arrive late Sunday, peak Monday and slowly decline Tuesday. A storm low, currently just east of Japan, will track east over the next several days, generating a similar size, mid- period west- northwest swell. This swell is expected to arrive late Tuesday, peak Wednesday before declining Thursday. This swell source may re-intensify north of the island sending a second pulse of a slightly larger, short- period north swell late next week.
Surf along east facing shores will remain rough and choppy through the weekend, trending down through much of next week as wind speeds taper off.
Surf along south facing shores will remain small through mid- week next week as background southwest and southeast swells fill in.
