Frequently asked

When do leaves peak in Montana in 2026?
Peak color is predicted for October 3–October 13 (best estimate October 8). Color starts around September 24 and trees are mostly bare by October 27.
How reliable is the Montana 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 Montana's autumn season?
Montana is in the northern hemisphere, so its color season is autumn (September to November). The turn takes roughly 33 days end to end, centered on October 8, and the last 10 of those are thinning canopy rather than color.
