The Secret to When Leaves Change Color

It’s true. Everyone wants to be out when fall foliage is at its peak, but predicting peak colors isn’t easy. Fall foliage reports may be helpful. However, often they are not extremely accurate at the time of trip planning.  Here’s the secret on how to strategize and select the best days for photographing fall colors in the Northeastern United States.

Autumn in Northeastern Pennsylvania, United States

The timing of color changes in the leaves is primarily driven by the increasing length of night. As the days grow shorter and the nights grow longer and cooler, biochemical processes being to change the leaf from green to some fall color variation. Different tree species change colors at different times. In Pennsylvania, a few trees, such as Blackgum and Dogwood trees, show brilliant fiery reds in late August through September. Maple trees will become red and orange in late September and into early October. Oaks only show their yellow or red colors long after the Maple trees have shed their leaves, normally in October.

When to Book Travel for Peak Fall Foliage

Whether they realize it or not, this is the reason why many photographers opt for the last week of September through the first 10 days in October as the best window of days to book their travel.  This is particularly true for areas like the Poconos in Pennsylvania and the Catskills and Adirondacks in New York.

In New England, the northern areas of Maine and New Hampshire have leaves turning colors normally around mid-to-late September.  Then, the colors peak around the middle of October. In the southern areas, such as Massachusetts and Rhode Island, color will start later and can last up through October.  The color is later simply because of the delay of the longer nights reaching the northern states.  This is the reason that planning a trip for mid-October offers a higher probability of arriving for some type of vibrant colors throughout the landscape.
