Colorado fall foliage expected to be less vibrant due to drought

Ongoing drought conditions and extreme heat in Colorado’s High Country are expected to impact the vibrancy and timing of the autumn foliage season. Experts suggest that the lack of moisture and a dismal snowpack may result in an earlier, shorter, and less vivid color peak than in typical years.

Meteorologists and forest entomologists note that while aspen color change varies by region, the current dry conditions often push trees into dormancy sooner. This can cause leaves to fall before peak color is fully achieved. High-elevation areas, including Rocky Mountain National Park and Summit County, may see color changes as early as mid-to-late September, while the metro area and foothills could see changes closer to early October.
