Swell Summary
A small, medium to long period 4 to 5 foot northwest north swell (330-340 degree) has held through today and will slowly decline through Wednesday. This swell still has enough energy to produce over head high surf along the best targeted reefs, chest to head high in most other spots, into tomorrow afternoon. The next significant north swell will likely arrive Sunday and Monday. This near due north swell originating from a long solid gale fetch down the north great circle line from the Aleutians is forecast to come in large enough to push surf to High Surf Advisory heights early next week.
A moderate size, medium to long period south southwest swell (180-190 degree) is still coming in above forecast guidance. Local nearshore south buoys are observing a solid 3 to near 4 foot, 13 second period, south swell that is equating to many fun size waist to slightly above chest high sets along many southern exposures. The next long period south swell arrival Thursday will reinforce this ongoing steady swell.
Surf along west-facing shores will be influenced by a mixture of both north and south swells. Thus, expect western exposures to remain elevated as these ongoing north and south swells will hold or be slow to fall.
East-facing shore chop will not be overly rough and will steadily decline, or conditions will improve, as wind waves subside through late week in response to lighter trade flow.
