Jupiter doesn't really have a surface.
It is a gas giant, and the further down into the atmosphere you go, the heavier the gaseous density.
Go deep enough, and the gases behave like liquids because of the pressure.... but because it is pressurized gas, and not a true liquid, there's no rolling sea with waves at any point in the atmosphere.
Deep, deep within is thought to be a rocky core whose volume is slightly larger than the Earth.
But the pressure of the gases at that depth makes contemplating the surface of that rocky core not unlike contemplating the surface of the iron core inside Earth...
