Swell Summary
A northwest swell has peaked and will be subsiding slowly through Saturday. A small west-northwest swell is tabbed to arrive late Monday, peak Tuesday, then subside gradually through Wednesday. A small short period northwest pulse is slated to arrive Wednesday night and Thursday. Small surf will continue along the south facing shores into next week due to a series of long period swell from the southern hemisphere. The boost in the trade winds will raise the surf into the small to moderate range along the east facing shores into the weekend. The surf will trend smaller after Sunday as the trade wind diminishes.
