You would probably be lucky enough to have most nights go below 50 degrees once you hit Breckenridge.
I also thru-hiked the CT during July/August 2014, and I encountered a healthy population of mosquitoes during the ~150 miles north of Twin Lakes. South of Twin Lakes, the mozzies disappeared entirely.
