What August feels like
By August, Yosemite Falls is often dry or a stain on the granite, which surprises visitors who came for the photograph. The high country is the move — Tuolumne, the Cathedral Lakes, anything above the Valley. Wildfire smoke can settle in for days at a time.
Rain is genuinely rare — most years, August stays dry start to finish. about 17 afternoons top 90°.
