Fall Foliage in North America (Atlantic Coast)

North America is famous for its beautiful fall foliage. Fall foliage colors can vary considerably from year to year, depending on Autumn temperatures, rainfall, storms, and a host of other factors.

During the Autumn season, trees release a chemical called phytochrome, which slows down chlorophyll production and allows the tree to go dormant. As green chlorophyll recedes from the leaves, other colors begin to show.

Leaf pigment is also influenced by the amount and acidity of tree sap. Strongly acidic sap tends to result in reds and other bright colors, while less acidic sap produces more yellows or softer tones.

Depending on locations, travelers can expect to see a variety of foliage colors during Autumn.

Along the Atlantic Coast of North America, brightly colored fall foliage can usually be found in places such as the Canadian Maritimes, the New England states, Upstate New York, Pennsylvania, Ohio, and Maryland.
