Frequently asked

When do leaves peak in Idaho in 2026?
Peak color is predicted for September 29–October 21 (best estimate October 10). Color starts around September 23 and trees are mostly bare by October 31.
How reliable is the Idaho forecast?
The forecast blends recent-year weather normals with photoperiod and elevation; it tightens as the season approaches. Against published peak dates the model lands within a few days for most regions, but it can be a week or more out. Mountains and coastlines are the hardest. Higher elevations turn roughly one day earlier per 300 m.
When is Idaho's autumn season?
Idaho is in the northern hemisphere, so its color season is autumn (September to November). The turn takes roughly 39 days end to end, centered on October 10, and the last 12 of those are thinning canopy rather than color.
