The 2025 fall foliage season promises vibrant displays in regions like New England, the Colorado Rockies, the Plains, and the Midwest, thanks to favorable weather conditions. Cool nights, sunny days, and a healthy growing season are key to bright colors. Early frost might affect parts of the Dakotas and Minnesota, while wind from tropical storms could impact the Carolinas. Duller colors are expected in the Appalachians due to insect and fungus damage, and in the Pacific Northwest and California due to drought and wildfire smoke. Climate change is causing increased variability, affecting both the timing and vibrancy of autumn foliage. https://www.accuweather.com/en/weather-forecasts/fall-foliage-2025-where-to-expect-the-best-color/1809883
