bottle beer storage temps..

I am running out of usable space to keep my bottled beers in my house (no basement) , before i am ready to put them in the fridge and drink. I am wondering what kinds of problems i would run into if i store my bottles in my garage that is reading close to 80 degrees during the day, and will get a little hotter over the next couple months. The beers i am thinking about moving out to the garage have already sat at room temp for 3 weeks or more, but i wasn't sure if they would go bad if the temp rises in the mid 80's for a month or so before they are drank?

In general, storing beer at higher temps won't hurt the beer (unless you get too high). Some people think that changing beer temperature causes skunking, but it's really sunlight you need to worry about.
