Mt Whitney Zone Forums General Discussion July or August for Whitney/JMT?

Hello experts,

I plan on hiking the JMT northbound this summer. I could either hike from 7/16-8/7 or 7/28-8/21, are either of these dates good or should I plan a later start? Which dates would you choose? I've read that mosquitos and snow can be an issue in July.

Again, thank you for your input.
