Swell Summary

A series of north swells will move through the coastal waters this week. A recent small north pulse will be reinforced by a larger, medium period north-northwest swell tonight through Wednesday. An even larger north swell follows Thursday night and Friday that will likely drive late week north facing shore surf heights to High Surf Advisory levels.

Weakened trades equates to lower east facing shore surf through the middle of the week. Strengthening trades on Friday will lead to increasing surf along the eastern shores with this heightened east wind wave chop persisting through the weekend.

Small surf along the south facing shores will get a minor boost today as a small, but relatively long 14 to 16 second period south swell travels around the chain. This swell will linger through Wednesday before tapering off at the end of the week.
