Squamish would be awesome but not much worthwhile sport stuff (its trad).
Skaha is fun, shorter & not as inspiring as Araps but some bits are equally as good rock. DON'T go in August unless its raining in Squamish, it'll be 40deg c. Skaha is best April-now or Sept-Nov.
The Rockies is perfect weather in August - esoteric but still good climbing. The bolted stuff follows the good rock more than trad routes can, plenty of lower cragging & good multi-pitch sport routes with a big mountain backdrop. Tonnes of bolted stuff to do. a few routes at the back of the Lake remind me of Araps. 80% of the ppl who go there only clips bolts, but its always worth taking a small trad rack there.
Colorado is high elevation so no doubt there'd be stuff to do there - loottts of good micro brew beer in Colorado also!
