New Castle, DE Overview

With just 5,175 residents, an inviting small-town atmosphere, and an excellent school system, historic New Castle is beginning to lose its status as “One of Delaware’s best-kept secrets.”  As more people awaken to the advantages of this area south of Wilmington, both long-established neighborhoods and new developments are attracting waves of newcomers.  Accessible by many north/south routes including the scenic Delaware 9, the New Castle area is just 35 miles from the state capital of Dover and a short distance from Wilmington’s shopping and cultural amenities.  The wide variety of attractive housing is part of the allure, ranging from rambling country estates to affordable single-family homes.  Starter homes are as abundant as larger family colonials, ranches, contemporaries, townhomes, or luxurious custom designs.  Few locales in Delaware can rival New Castle for creating a postcard-perfect setting.  Adding to the atmosphere are attractions like the scenic Battery Park Trail, the New Castle Courthouse, a collection of charming colonial and Victorian homes, and wonderful museums.

Climate and Weather

The Temperature chart displays average high and low values for January and July, and is designed to provide an indication of both seasonal and daily temperature variability. The Weather Risk Index indicates the calculated risk of each type of weather event occurring in the future. This risk is based on historical localized storm events and weather patterns. The national average for each type of weather event equals a score of 100, so a score of 200 would represent twice the risk as the national average, and a score of 50 would represent half the risk of the national average.
