Make sure all your roof downspouts are directed away from the house and make sure they are not clogged.
If you have a footing drain that can daylight,make sure it is daylighted,and unclogged.
make sure the ground slopes away from your house on all sides.
It could be that no one put in a footing drain.
If your basement is not a walk out basement then depending upon the topography, a footing drain may not be able to be daylighted.If that's the case,sounds like you need a sump and sump pump in your basement.
You could consider an inside perimeter drain system that goes to a sump with a sump pump in your basement.
I run a dehumidifier in my basement during the summer and that keeps the humidity down .
I also prefer the basement for a safe because if there is a fire,the safe would just fall through the floor and smash everything that is inside and would possibly cause more damage than the fire itself. Also in the basement, temps should not be as high especially if the safe is up against the foundation wall.
