Condensation issue

Is it coming from below, or condensing on the surface? I have that occasionally if one of my doors isn't completely closed. Warm moist air flows in over the cold concrete and condensates on the floor. Curious if it does it all the time, or just on days that were cold at night and warm up considerably during the day.

What condition are your door seals in? I have one of my three doors that has a bad bottom seal (no seal at the edges) and I get condensation in the areas around it at times if the conditions are right.

Just a thought.....
