Swell Summary

Declining north-northwest and west-northwest swells will keep small to tiny surf in place over the next few days before a small northwest swell gives a slight bump to north shores on Thursday and Friday. This will then be followed by a slightly larger north- northwest swell this weekend and a potentially larger long period west- northwest swell early next week from a forecasted storm force low developing northeast of Japan in the next few days.

Small background south swells will keep relatively small surf for south facing shores through much of the week. A moderate south- southwest swell is expected this weekend, and could bring surf heights above seasonal averages.

Rough trade wind swell will produce east shore surf just above seasonal average through Tuesday, then decline later in the week as trade winds decrease.
