Swell Summary

A large NNW swell (340 degrees) has rapidly built in overnight over the western half of the state, and a High Surf Warning (HSW) has been issued for shores most exposed to the swell, with a High Surf Advisory for shores less exposed.

While the predominant period of the primary NNW (340 degrees) swell train will be around 14 seconds, the proximity of near gale force winds over waters just NW of the area will introduce a wide spectrum of wave energy extending into the shorter periods, resulting in rough and choppy surf along exposed N facing shores. The increasing seas will require an SCA for most waters through Tuesday. The swell will transition increasingly northerly (360 degrees) as it gradually diminishes late Monday/Tuesday.

A small S swell will gradually decline over the next couple of days. A small to moderate long-period NW (320 degrees) swell is expected Wednesday night and Thursday, followed by the potential for a very large NW (320 degrees) swell by the end of the week.

Surf along E facing shores will remain rough and choppy as the trade winds build back this week. Although, E facing shores exposed to the N swell wrap will see a rise coinciding with the N swell.
