Swell Summary
A small, short-period, NNW swell fades this afternoon into tonight. Small background energy from the W this weekend into next week from Typhoon Sinlaku, but confidence remains low. A much larger NW to WNW swell is possible towards the end of next week as Typhoon Sinlaku transitions to extratropical early next week.
A small to moderate, medium-period, SSE swell boosts surf along S shores through Friday then lowers over the weekend. Surf along E shores remains below the seasonal average as trades remain light. However, increasing trades by week's end should brings a slight bump to surf. Low pressure advancing S along the W coast of the US next week then sends a small, medium period NE swell toward the islands by midweek.
