This year is going to be fantastic for fall colors. Dr. Dan West, an entomologist for CSU Forest Service says “We had a delayed spring, two to three weeks late because of how cool and wet things were. The ample precipitation means great growing conditions. Healthy stands of trees show a more vibrant color than non-healthy stands, and they’ve had perfect growing conditions all summer.” This fall is going to be amazing!
Generally the leaves change every year about the same time but so you can plan for optimal outdoor leaf peeping experience, make sure you know when forecasters predict the colors to be at their best.
