Autumn is a popular season in the Northeast due to the beautiful changing colors of the broadleaf trees. As temperatures fall and daylight decreases in September and October, the leaves stop producing green pigment and take on vibrant red, orange, and yellow hues. These colors last only a few weeks before the leaves die and fall from the trees. The Northeast has many forests due to its proximity to the ocean and high levels of precipitation, providing trees with the water they need to thrive. Tourism increases during autumn as city residents travel to rural areas to view the colorful foliage.
