With the start of meteorological fall coming up fast (September 1st marks the start), many people have already planned or are currently planning their autumn leaf-peeping adventures. If you’re hoping to get a good view of the colors this fall, you’d better start planning quick. With Vermont being one of the most popular states for leaf-peeping, we took a look at the fall foliage forecast from ExploreFall.com for the Green Mountain State.

The vibrant fall colors won’t start coming out in Vermont until around September 15th, with ExploreFall.com forecasting some minor colors coming out in the northern portions of the state. However leaf peepers may find themselves disappointed if they make the trip this early.

By September 25th, a significant majority of the state will be seeing low concentrations of fall colors. In a few select area in the north, the color concentrations may be growing to a medium. Still, waiting until October is likely best for leaf peeping fans.

If you’re heading up to Vermont by October 25th, there’s a chance you’ve already missed the peak. Much of the state will be beyond peak colors aside from a few areas in the western portion near Lake Chamlain.

What Controls The Timing of Fall Foliage?

Two major factors influence the timing of fall foliage: temperature and daylight. As the days grow shorter, leaves slow the process of photosynthesis to a halt and leaves begin to lower their concentrations of chlorophyll. Less concentrated chemicals like anthocyanin and carotenoids dominate, causing the leaves to change color. The further north and the higher in elevation a tree, the sooner it begins to show its fall colors.
