Why do leaves change color in the fall?

Weather News

CHICOPEE, Mass. (WWLP) – The fall foliage season is looked forward to by so many people but what is the reason the leaves start to change color?

Leaves start their shutdown and falling process during this time of year because the area is losing daylight. Since the summer solstice, there has been a decrease of 2 hours and 48 minutes of daylight. This difference in daylight has made some leaves across the pioneer valley start this process, but not as much as some other locations in New England.

The areas that are nearing peak already are in Northern Vermont, Northern New Hampshire and parts of Maine. In our backyards we only have a few trees starting to change color. This is putting Western Massachusetts at the “patchy” section. Now with all of the rainfall measured this past summer, that could play a role in how vibrant the colors are and the exact peak date. Nonetheless, residents can still expect a great season here.
