I've only had it in this room for three days. It was outside (but covered) for two days after I purchased it (pretty hot days). So it probably does have a lot of heat built up within the structure.

But... The temperature inside the room where this safe is currently located is 93 degrees. Also my outdoor thermometer is reading 98 degrees outside my house. So it's safe to say this room will be fairly hot during the summer months...

Down deep I am telling myself I'd better move it to a place within my home that is air conditioned but it will be a bear to move it...
