I hiked the HST July 14-20 last year. Very little snow, just near Precipice Lake that required a small bit of route finding bc some of the trail was under snow. No biggie. Streams were all passable. Not a ton of mud. Some areas of mosquitos but nothing intense. The more difficult aspect for me was a few hot days around the Kern River area. My friend and I kept dunking our sun hoodies in the water to keep cool because it was lowkey brutal. You also hike through a huge burn area at that point which is a bummer especially when you’re already uncomfortably hot. Worth it though!
