Swell Summary
North shore surf will remain small today, before a couple overlapping northwest swells bring a small boost to north and west facing shores Monday through Wednesday. Surf along north facing shores will then trend down Thursday and fall back into the very small range Friday into next weekend. The current south swell will gradually decline today, with only small background southerly swells expected Monday through late this week. Persistent trade winds over and upstream of the islands will keep east shore surf relatively unchanged through late this week.
