Questions

Is モワッと the same as being humid?

It often implies high humidity. Air that is モワッとした is usually hot, moist, and therefore feels thick and suffocating.

Can I use it for perfume?

Yes, if someone puts on far too much perfume and the scent hangs in the air like a thick, overwhelming cloud.

What is the difference between モワッと and ムワッと (muwatto)?

They are nearly identical. Some native speakers feel ムワッと sounds slightly heavier and denser, but they are generally interchangeable.
