Most likely be pretty good. Last spring we were climbing at the loaf whenever we needed a break from snowboarding. If you get there early you can hit the classics on the east side in the sun and the follow it to the westside. I would bet it will be nice.
I just rode by Sugarloaf yesterday, and it looked to be pretty dry near the cliffs. If you're looking for a climbing partner, I'd be interested, pm me, I'm kinda new to the area... if not, that's cool too.
