Sources: 5. Developments: 2. Colorado’s autumn foliage season is facing significant challenges due to persistent drought and unusually warm temperatures. Environmental stressors, including a lack of moisture and extreme heat, are expected to reduce the vibrancy and duration of the seasonal color changes. Experts note that trees may enter dormancy prematurely as a survival mechanism to conserve water, potentially leading to an earlier peak and less vivid colors. While some monsoonal moisture has appeared, late-summer precipitation has remained below normal levels. A dismal snowpack has further exacerbated these conditions. Meteorologists and forest entomologists suggest that the current dry conditions often push trees into dormancy sooner, which can cause leaves to fall before peak color is fully achieved. Color changes are anticipated in higher elevations, such as Rocky Mountain National Park and Summit County, during mid-to-late September, while changes in the foothills and metro areas are expected around early October. ## Timeline ### 2026-09-04: Colorado fall foliage expected to be less vibrant due to drought Drought and extreme heat in Colorado are expected to cause an earlier, shorter, and less vibrant fall foliage season this year. 4 sources. https://clstr.news/cluster/colorado-drought-expected-to-reduce-fall-foliage-vibrancy ### 2026-08-27: Colorado fall foliage faces impact from drought and warmth Drought and warm temperatures may lead to less vibrant and shorter fall foliage seasons in Colorado, though scenic drives like Kebler Pass and the San Juan Skyway remain key destinations. 2 sources. https://clstr.news/cluster/colorado-fall-foliage-faces-impact-from-drought-and-warmth --- Cite as: Colorado drought impact on autumn foliage.
