dumb question, rollers

I hear a Erie wave forecast and it says that the forecast is 1 to 3 with rollers.

So the question is how does that forecast compare to just 1 to 3  period?

What would the difference be?

    Rollers have a very long wave length ( distance between peaks ), and chop, a shorter wave length. I think it depends on the wind patterns over the whole lake. Let's say the winds are north at 15 mph. in the area around Erie, but a different direction or speed, elsewhere on the lake. You might see 3 foot CHOP. Now let's say the wind is north at a lesser speed ( 7-8 mph.), but pretty much the same over the entire lake. You might see 3 foot ROLLERS.

    Choppers/Cutters at 1 to 3s not much fun to fish, especially if there is a chance they can build to to 2 to 4s
     
    Rollers 1 to 3s, not bad at all.

    Rollers are also created when there is a really rough lake, then the wind calms quickly. You'll lose the caps but still have large rolling waves for a few hours after the wind dies.

    Swell size is typically the average height of the largest 33% of waves in a set, measured from the highest point of a wave (peak) to the lowest point (trough). Swell size is also known as the significant wave height and it is the cube of the significant wave height that typically is used as the important component of the equation to calculate how much energy that wave has to erode a coastline.
     
    Period is the average length of time between each wave in a set. The significant period is the average period between the third largest waves in a wave record.
     
    This was taken from; http://en.wikipedia.org/wiki/Swell_%28ocean%29
    It tells of ocean waves, but the waves that are on the Great Lakes are the same.
