Here in Wisconsin we go from 20% in winter to 75% or higher in the 
summer.  I've found that a winter/low humidity application of CA is more 
effective and longer lasting than a summer/high humidity application.  I 
theorize that the CA penetrates more thoroughly into a dry block, 
whereas in a moist block it may not even get past the bushings, and may 
begin curing before it has fully penetrated.
YMMV
