Looking for tips on storing cards in hot/humid climate. 80-100 F consistently between May and October. Have an attached garage but not climate controlled (also an above attic garage). Mostly late 80-early 90 junk wax as I've run out of space inside to store. 
 

I don't want to brick or warp any cards but it is always humid early Spring to late summer. Any tips? 

There's a few tips in this article that may be helpful:

Thank you! I have read a little bit since posting but came here first because I thought someone else might have good tested ideas. Thanks for sharing the link! 

I had many of my duplicates in unregulated storage which not only had no climate control, but it leaked! The vast majority of the cards were fine. The ones that were stacked neatly are undamaged but the ones that slid around and were not neat did take damage and stuck. 

So if you stack them neatly I think you'd be fine. 

Put plastic cards in penny sleeves. I found out the hard way that the plastic cards will damage the cards around them. I actually found an upgrade/replacement for one that got damaged by a plastic card in my unregulated storage unit, where the one that got damaged never went more than 30 feet away from me. 

That's awful about the leak but good thing it didn't do much damage! I did an initial quick run through over about 6 hours looking for any 2001 Topps (the lot didn't go past 2001), Chrome, foil, glossy/plastic/similar type cards, plus any cards I saw that are worth more than the 4,000 1988+1990 Donruss cards (haha) and brought them inside. Today is cleaning day so I hope to have everything all set by tonight! 
 

thanks again for the tips!
