A large long-period northwest swell has been building overnight. This swell is expected to peak today before slowly fading through Monday. A gale north of the area has produced a smaller and shorter-period north swell. That swell is expected to gradually shift out of the north-northeast.
Nothing significant expected out of the South Pacific.
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.
