Swell Summary

Small surf along the north and west facing shores will hold today from a small north-northwest (320-330 degree) swell. A moderate sized long period northwest (320 degree) swell will arrive Monday, peak Tuesday, then gradually lower Wednesday through Friday. This next swell will produce a large increase to north and west shore surf heights from late Monday through Wednesday, approaching High Surf Advisory (HSA) levels as the swell energy peaks on Tuesday.

Small surf along the south facing shores remains in the forecast today. A new long period south-southwest (200-210 degree) swell will build from Monday night to Tuesday, peaking Wednesday and Thursday near HSA levels. This swell energy will then gradually lower from Friday into next weekend.
