The local flora is in full bloom, making it a lovely time for outdoor activities such as walking along the Nanticoke River or exploring the nearby Adkins Arboretum. It's also a good period for fishing and boating on the river.Early autumn, from September to October, brings comfortable weather with cooler temperatures and vibrant foliage. This season is ideal for enjoying the natural beauty of the Eastern Shore, with opportunities for scenic drives and enjoying local produce from farm stands.
