Weather in September

September begins the lovely fall season in Delaware with mild conditions amid partly cloudy skies. The rainfall sees an increase with the departure of the hot summer temperatures. Summer thunderstorms exit the state by the early fall season, and the weather is comfortable with many sunny days in the month.
The average temperatures register in the 59°F (15°C) to 79°F (26.1°C) range with a significant drop in humidity. Fall brings chilly days with crisp air and plenty of festivals. Apple orchards and pumpkin patches provide ample takings as the festival season arrives in the state. The northern part of the state sees lower temperatures compared to the south.
Delightful mornings and breezy evenings are the signatures of the autumn. A light jacket keeps the rain away during the day and protects from the cold during the evening. Early fall is an excellent time to visit Delaware with the dwindling of summer crowds and drop in temperatures.
