Tapes on the shelf will withstand those conditions (use a closed, sealable 
cabinet and toss a bag of silica gel decissicant in there every once in a 
while if need be [they recycle if you heat them up to 300F/150C]), but 
humidity that high is going to be nasty for equipment life in general and is 
going to be borderline for the tape drive while in operation itself.

That's not me.  I've dealt with more than one server room buildout, and I'm 
familiar with backup media interacting with environmental conditions, but 
climate control of the server room has always been a requirement (in the 
positive sense).  The temperature you're describing isn't really a problem if 
you've got adequate air circulation through the racks, but the humidity is 
something else.
