I arrived in Brighton on October 16th almost 40 years ago. The trees were rich in color on that day, and I’ve used that date as the annual peak color day ever since. While we’ve certainly had nice autumn color, it seems like we’re running about a week late this year.
We’ve had chilly nights, but not below freezing yet. That’s one of the reasons, but I don’t fully know all of the factors that influence the trees to stop chlorophyll production so the true colors of the leaves emerge. Maybe our cool August and frequent rains have played a part in prolonging the growing season. These are maple leaves but I don’t know which species.
