As most have stated it is not really the temperature but the humidity that is the nemesis for all guns.
I like like to use Corrosion X HD on all my guns. I make sure that I spray it on all bare metals and wipe off the excess grease. I have a gun I hide in the garage wrapped in a rag to protect it from dust. To this day it has never had any rust spots.
