|---|---|
| Starts as a plunging wave but the wave ends up catching up to the top of the wave and rolling into the beach at different levels. | Surging Breaker |
| When the top of the wave curls over the bottom causing a tunnel like wave wave until it finally breaks. | Plunging Breaker |
| These are waves that break slowly as they go to the shore. | Spilling breakers |
