Flowers begin to bloom as spring settles in throughout Delaware and the Brandywine Valley during the months of April and May. Temperatures climb steadily into the summer months and stay warm from June through August with temperatures that range from the mid-80s to the mid-90s, this is when you'll see kayakers and tubers take to our local rivers to beat the heat. Cooler weather typically arrives in late September, and the leaves begin to change in early October. The Brandywine Valley is renowned for its beauty at the height of the fall foliage season, which usually runs from mid-October through very mid-November. Expect fall temps to chilly evenings in the 40s and 50s and days that range from 55 to 75.
Sweater season tends to linger until early December when the winter jackets come out, and while Wilmington can have an occasional white Christmas, most of the snow that comes falls between January and March. The winter months typically range from the 20s to the 40s and see one or two significant snowfalls and cold spells that might freeze local lakes and streams - as well as the ice-skating rink on the Wilmington Riverfront.
