Autumnal changes are progressing across New York. Initial reports indicate that fall foliage is beginning to emerge, with the most significant color shifts occurring in the Adirondacks, where areas like Old Forge and Tupper Lake show between 20% and 35% change. Other regions, including Central New York and the Hudson Valley, have reported more subtle color shifts of 5% to 10%.

In the Hudson Valley, the official arrival of autumn is marked by the start of the leaf-peeping season, which is often accompanied by special Metro North trains for tourists. Local communities are engaging in seasonal activities such as fall festivals, craft fairs, pumpkin decorating, and ‘pick-your-own’ farm experiences for apples and pumpkins. Specific celebrations, including Halloween events in Sleepy Hollow, are also beginning to emerge.

As of mid-October, trees in Central Park remain approximately 80% green. While full color typically does not arrive until late October or early November, the seasonal transition is being noted by the scent of fallen leaves and cooling temperatures. In Upstate New York, observers continue to have time to view the changing foliage as the season progresses.
