Swell Summary

Two overlapping northwest swells will increase surf heights along north and west shores through Sunday. These surf heights may approach High Surf Advisory levels this weekend and then decline on Monday. A small medium period north-northeast swell arriving Monday night should keep surf heights elevated along north facing shores with some wrap into eastern shores through Wednesday. East facing surf heights will begin to rise today as trade winds begin to increase upstream of the Hawaiian Islands. Stronger trade winds this weekend will boost surf heights along east facing shores into early next week. South facing shores will remain flat through the week.
