A heavily shadowed swell is building and will peak on Thursday. The swell will likely reach the west side of the Big Island and a high surf warning has been posted for the west facing shores. Surf is also expected to rise along the north facing shores of the Big Island, where an advisory has been issued. Surf along that coast will be significantly higher than the west side.
A good sized west-northwest is due in late on Valentine’s Day.
Our current southwest swell continues to slowly fade Thursday. A small new south-southwest is expected Friday and Saturday.
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.
