Swell Summary

North shores are nearly flat with a few spots seeing tiny surf this afternoon. A small pulse of energy from the north should produce more widespread (tiny) surf on Saturday. The next larger pulse for north- facing shores will be a small to moderate, medium-period northwest swell arriving Monday night and filling in by mid-week. Low pressure advancing south along the west coast of the US next week also produces a moderate, medium period northeast swell that arrives Tuesday and peaks around the middle of next week.

A small to moderate, medium-period SSE swell will begin to subside tonight and fade through the weekend. Surf is expected to return to background levels along south facing shores by early next week. Surf along east-facing shores remains below the seasonal average as trades remain light. The aforementioned northeast swell also boosts surf along east-facing shores mid-next week. Small background energy from the west will be possible this weekend into next week from Typhoon Sinlaku, but confidence remains low.
