Swell Summary
The current medium-period north-northwest swell will continue to slowly fade this evening, maintaining below average levels for this time of year. The first of two long to medium period overlapping northwest swell pulses started trickling in earlier this afternoon, and will gradually build surf along north and west facing shores into Tuesday. The following bigger pulse will arrive late Tuesday into Wednesday, further boosting surf heights and possibly reaching High Surf Advisory levels by Wednesday. Near-average surf heights will generally hold into Thursday and decline heading into the weekend.
Choppy east shore surf will remain small and decline for the next few days as trades ease. Expect minimal background surf for south facing shores, with only a minor south-southwest pulse expected Wednesday into Thursday, keeping south shore surf heights just above flat levels.
