Swell Summary
The northeast swell will fade over the next couple of days resulting in surf quickly dropping along east facing shores over the next couple of days.
A mix of and incoming small, long period northwest swell and the fading northeast swell mentioned above will provide a little boost to west facings shores and allow north facing shore surf to drop more steadily today into Sunday. A large, medium- period, north- northwest (340-350 deg) swell should arrive late Sunday, peak above the warning threshold on Monday. This swell will then transition to a more northerly direction Tuesday, before slowly subsiding Wednesday into Thursday. In the longer range forecast, an even larger northwest swell may develop late next week with surf heights possibly exceeding warning levels along north facing shores.
An out of season south swell will continue to build today, peak tonight into Sunday near summer average, before declining early next week.
