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:
