Swell Summary

Small south and southeast swells are expected to produce below typical summertime surf heights along south facing shores into Friday. Forerunners from a new, long-period south swell are expected to arrive late Friday night. This swell will likely produce near to slightly above average surf along south facing shores from this weekend into early next week. Surf will remain small along east facing shores until trade winds strengthen further. As they do, modest, choppy surf will return along east facing shores, lasting from this weekend into early next week. Expect nearly flat conditions along north facing shores. However, small, short-period north- northwest swells beginning later today may provide a slight boost in surf heights along exposed north facing shores through this weekend. Models show a slightly larger and longer period northwest swell arriving early next week.
