Even in August, at 10k and higher....it is not uncommon to drop into the 20's and for flakes to fall.
... which all happened on the 2012 ride. We had blowing sideways sleet/snow on top of a pass. Our coldest night was 20 degrees at over 10K feet one night. A couple other nights we had rain during the night. And, we also had a day or two where temps reached over 90F.
It's best to be prepared, including bringing your tent fly and installing it every night.
More importantly, we had an awesome week of riding that every one of us will remember for the rest of our lives.
Yes, it's that awesome!
