"Normal waves heave up and down in the direction they move, whereas anti-waves do the opposite."

That certainly clarifies things.

Right.

Do “anti-waves” heave down and up in the direction they move (as opposed to up and down)?

Or do they heave up and down in the direction they are NOT moving?

Or do they heave side to side in an anti-clockwise direction but only in the northern hemisphere?

Or maye they sit perfectly still, but they do it in the direction they are NOT moving?

I’m SO confused.
