Water Everywhere...
Temperature was 60F on Thursday here in northern Ohio so I went to the hanger to visit the airplane. Very upsetting to see conditions in the hanger. The bed sheet covering the canopy was soaking wet as if it was just removed from a washing machine. Bottom of wings were dripping water as if plane was just washed with a hose. Humidity at 100% and cool concrete floor and cool aircraft sheet metal condensed water everywhere. I hate to think about sensitive electronics and wiring connections.
I hate it when this happens?

We get this pretty regularly this time of the year in Florida. I use golden rod dehumidifiers with a small fan in the planes and especially in the toolbox. Otherwise thousands of dollars of tools turn to instant rust. Keeps the humidity at bay when everything else is soaked

I've seen that a couple of times in my hangar. Disconcerting, isn't it?

Welcome to my world. We refer to the hangar as "Seaplane base D7". Not only does condensation rain off the roof supports, any time it rains the water comes in under the door and we get about an inch on the floor. Makes it miserable to try and work in there.
The airplane doesn't seem to mind, but it's a challenge keeping it clean.

My very well insulated hangar in houston did this one time last year. I installed a 70 pint dehumidifier that now runs 24/7. It keeps the humidity at 45% regardless of outside conditions. I have not had any further problems.

I know it wasn't funny to you, but it's pretty funny to anyone living in the deep south to hear someone complaining about that. :-)
Humidity above 80% is almost the norm down here, and 30 degree daily temp swings are common. Everything metal in my hangar is wet almost every morning, except in the coldest and hottest weather. I have a tractor parked inside the hangar, and there are large puddles of water under both rear tires every morning (lots of chilled mass in the water in the back tires, so they 'sweat' like a tall glass of iced tea).
Like Dale said....

Cold soaked object comes into contact with warm air. Water vapor will condense on contact. No different than a glass full of icewater. The way to prevent this is heat your hangar and airplane any time a sudden temperature swing from cold to warm occurs.

We insulated and heated our attached hangar at our airpark home back in 2000. We keep the hangar heated to 45 degrees all winter. The efficient Modine style gas heaters cost very little to heat to 45 and nice to bump up to 62 when working out there. We don't have a plane anymore, but the cars and boat really love the warm air. Our hangar is about 1800 sq. ft. with 14 ft. ceilings. In Wisconsin.
