Swell Summary
Surf along all shores will remain relatively small today. A long- period east swell is expected to arrive by tonight, peak near 4 feet Tuesday and Wednesday, then lower Wednesday night and Thursday. As the longer-period E swell diminishes, short-period trade wind swell will build to near seasonal norms. A small, medium-period south-southeast swell, with a a pinch of southwest swell energy as well, will support small surf along south facing shores the next couple of days.
