Best time in year for rock climbing in Whistler?

As I hear this Whistler is one of the best destinations in Canada for rock climbing, so is there anyone who could give me more info on when would be the best time of the year to go there if this is the only purpose of the trip? I am seriously thinking of going there this summer, but I am not sure if my timing would be right.

Summer is, without any doubt, the best time to go rock climbing in Whistler, so your timing could not be better. Yes, if it is a great destination for rock climbing, and you will surely have great time. It has been a while from the last time I did something like that, and I am a bit envious, you know.
