2021 Fall Foliage Forecast: Later Start, Bright Colors Expected

2021 Fall Foliage Forecast: Later Start, Bright Colors Expected

After a hot summer, temperatures have cooled somewhat slower than normal with the onset of Fall. Above average temperatures are expected for much of October, meaning fall foliage season will be a little behind schedule, but that does not mean we won’t see vibrant colors here in Pennsylvania.

Recent heavy rain that has occurred in much of the state over the past few months may mean we see less bright reds, and more yellows and oranges. Areas of northern and western Pennsylvania that dodged the heavy rain may be treated with the best colors this foliage season. But there is still a chance for the rest of us, thanks to the recent very dry stretch of weather and cool, crisp early fall mornings.
