What September feels like
September is the reward for skipping summer: the crowds drop after Labor Day, the light stretches out, and the high country stays open and glorious. The falls are at their lowest, so come for the rock rather than the water.
Real rain shows up maybe one day all month; the rest stay dry. about 7 afternoons top 90°.
