Monster 696 hot weather belt tensioning

[obsidian gt]

So as the title implies, do any of you guys have problems with your timing belts getting really tight when it's really hot?  Recently in DC, it has been over 100 degrees, and by the time I get home from work, my belt tensioners ( I think, I guess it could be the belts) have been squealing.  Do any of you guys loosen your belt tension during the summer months?  FWIW, I had my 7500 mi service done last fall, but I supplied the cycle works belts.  Thanks!
