What was Noah's physical description?

The Bible does not say what Noah looked like. However, Noah was 'perfect in his generations'. This is true of Noah spiritually, but it also meant that Noah came from pure stock and did not inter-marry like the others did :- Gen 6:9 KJV These are the generations of Noah: Noah was a just man and perfect in his generations, and Noah walked with God.

This means that Noah would probably have looked like any typical Jew today.
