Swell Summary
Moderate to long period NW swell energy will generally persist over the next couple of days as a series of NW swells filter across the area, maintaining near to above average surf along north-facing shores through Friday. A brief, NNW swell may move through late Friday, but should taper off quickly on Saturday. Surf along north-facing shores will trend down through the weekend.
A series of small, medium to long period S swells will continue to filter into the area through the rest of the week and into the weekend, keeping south-facing shores from going flat. East-facing shores will remain small through the near term, but will see increasing short period action as trades strengthen over the latter part of the week.
