If you’re a southerner, the temps right now are fine. It’s not abnormally hot. By mid-August, the nights usually begin to cool a bit and sometimes you catch a cool front this time of year (we did on our hike last August 6-8 last year). I did a section hike one month ago (July 7-9) and it was seasonably warm, but fine. Too, you’ll be at a fairly high elevation, so that helps. If you’re doing the vicinity of Tray Mountain or Standing Indian Mountain, the forecast for Highlands, NC should give you a good idea of what to expect - probably no more than low 80s with 60s at night. Finally, there’s shade almost the entire day since there are few gaps in the foliage in Georgia this time of year.
