No, not necessarily. It matters which cardinal direction each wall faces.

And what you've said about it being more pronounced up near the ceiling does not square with my understanding of the situation. It matters where the air supply diffusers are directed, the position of the doors and windows, and other factors like insulation.

I'm not saying there's definitely no additional water intrusion, but I'm not understanding the reasoning you're using.

Edit: thanks for confirming that the "reasoning" you're using here is... None. Suspicion. Alarmism.
