Swell Summary
North shore surf will be below April average through most of the week. The combination of a small north-northwest swell and wrapping wind swell will decline on Saturday. A northwest swell due on Monday will push surf to near April average, followed by a decline Tuesday and Wednesday. A larger north-northwest swell may arrive Thursday.
Rough, trade wind-driven seas peaked earlier today and will slowly decline this weekend. Elevated rough surf along east facing shores of most islands will decline to near April average on Saturday and subside below average Sunday into early next week.
Surf along south facing shores will be below April average this week, with the current small south swell declining on Saturday.
