Swell Summary

The current northwest (310-320 degree) swell will quickly decline today and Thursday. A High Surf Warning (HSW) remains in effect this morning for most north and west facing shores, however we may transition to a High Surf Advisory for these areas by this afternoon as swell heights may fall below warning thresholds later today. Another northwest (310-320 direction) swell fills into the region on Thursday. Surf heights with this next swell will approach HSW levels as swell heights peak near 12 feet from Friday to Saturday. Surf heights will remain elevated along north and west facing shores into early next week.

Small surf heights are expected along east and south facing shores through the week.
