high humidity levels during epoxying

It's August and I'm ready to epoxy my craft.  We have high humidity levels that will delay the curing process.  What is the optimal humidity level for epoxying?

 

P.S.  I am building this in my garage. 

System 3 epoxy doesn't care what the humidity levels are. As long as you cna breathe the air the epoxy will cure. I just applied some the other day when it was 87%, also in my garage. Go for it.
