The air is crisp, we are wearing layers of clothing while being outdoors hiking and working in our gardens. It is one of my favorite times of the year, as long as it not rainy.
My best prediction for best fall colors in the Berkshires is the 2nd week of October. In 2018 the fall colors seemed dull here but in Northern Michigan they were spectacular, while we were in Traverse City, Michigan and Leelanau County.
So enjoy your last days of decent outdoor weather. This is an excellent time to plan any projects for spring 2020!
