I learned this myself last summer.  We have a cottage on northern Lake 
Michigan that is about 100 feet from the water.  There is a walk-out 
basement that gets somewhat damp, though a dehumidifier usually keeps it 
under control.  Last summer I opened the cottage later in the season 
than usual, and the basement was very clammy.  So I decided to open the 
slider doors and turn on a box fan to air things out...

When I came back downstairs a couple of hours later, *standing water* 
had condensed on the cold floor tiles!  I had basically been 
dehumidifying Lake Michigan.  Lesson learned (and I spent the rest of 
the vacation trying to dry things out again).

Thanks for all the other comments in this thread.  I'm absorbing and 
will try to summarize back to the group.
