However, Jupiter does have a very dynamic atmosphere, with swirling clouds of ammonia, water, and methane. These clouds can form massive storms, like the Great Red Spot, which is a giant storm that's been raging for centuries.
While there's no solid surface to get wet on Jupiter, the deep atmosphere does contain water vapor and ice crystals. So, you could say that the atmosphere is "wet" in a way, but not in the same sense as the surface of Earth.
