We started a couple of days after Smack in 05 (high snow year, particularly in southern/central california). If you’re prepared to deal with some snow (or walk round the worst bits) then its no problem. Fuller ridge had c. 12 miles of snow, the san bernadinos reportedly had a record amount but nobody really struggled, and the san gabriels had a lot but only for 10 miles, and most people took a clear, simple, scenic detour. We took our time, got to Kennedy Meadows 30th May, and hit the Sierra on 1st June. The conditions were challenging, but not as bad as much of the hype. That was a recurrent theme about most trail conditions.

and for comparisons between the sierra in and out of snow:

Gearlist is here:
http://homepage.ntlworld.com/davidtoms/Files/Gearweights.htm we only added ice axe, crampons & bear canister for the sierra, but carried on in trail runners.
I wouldn’t swap the experience we had for the world. It was amazing, wild and beautiful. Then again, seeing only 2 people on trail for 23 days might not be your idea of fun!
Have a great hike. Its an amazing trail, and I much preferred the sierra buried in snowpack vs late summer.
