What sea state means?

Are 3 ft seas rough?

What does seas 2 to 4 feet mean?
It means the boat will be rocking a lot but not unbearable, depending on how many seconds between waves. They usually say something like 4′ foot sea with 10 seconds which means 10 seconds between sets of waves. If its 2 to 3 seconds that means a lot more waves, closer together.
