Windfinder app and wave heights

[4x15mph]

I am using the wind finder app and looking at winds and wave heights for tomorrow. The app shows 3 feet wave heights in the Chesapeake bay (Northeast MD) and the other Delaware river area (Croydon, PA) that I am looking at. Really? 3+ foot waves on the river. Does this sound like this is possible and given that I only have a 19 footer, should I stay out. I want to make sure that I am reading this correctly since I know that I should not be in 3 foot waves. 1 foot tops is probably where I want to be

Anything over 1 foot was painful in my LX210.

I would use multiple sources when it comes to wave height and wind. There seems to be a great deal of variability between sources at times. I have used these with some good luck.
