What August feels like
August is when the valley's summer is at its most reliable and the crowds are at their thickest. Frost before dawn is genuinely possible even now — that is the elevation and the cold-air drainage rather than a fluke — and the huckleberries come in up in the higher country.
Expect about 4 days with real rain — enough to notice, not enough to plan around.
