Swell Summary

Existing medium to long period NW (320 degrees) swell will hold steady just shy of the High Surf Advisory (HSA) threshold through the first half of tonight. This swell will then subside late tonight into Tuesday. The lull in elevated surf will be short- lived as a larger long period NW (320) begins filling in during the day Tuesday. This swell is forecast to peak above the HSA threshold for N and W facing shores. During its peak, this swell will mix with a small, long period N (340-350) swell that will also peak Tuesday night into Wednesday.

Surf along E facing shores will be dominated by wind waves and short period fresh swell emanating from strong upstream trades. As trades further strengthen from Wednesday onward, surf will build to the HSA threshold (10 ft) along E facing shores perhaps as early as Tuesday night but confidence is higher in reaching the HSA threshold by Wednesday. Surf will build toward the High Surf Warning threshold for E facing shores by the end of the week.

Surf along S facing shores remains small through the period except where there is wrapping of longer period NW swell energy.
