Surf beat
From Coastal Wiki
Definition of Surf beat:
Long-periodic oscillation of the water line on the beach. The oscillation is related to Infragravity waves in the surf zone.
This is the common definition for Surf beat, other definitions can be discussed in the article

Notes
The surf beat period is typically in the order of one to a few minutes. Several infragravity wave motions can generate surf beat:
- Infragravity waves associated with wave groups[1]
- Edge waves [2]
- Oscillation of the wave set-up related to the breaking of wave groups in the surf zone [3]
