The rolling topograpy is typical of the Southeast Piedmont Region. Elevations run between 200 and 500 feet msl. The climate is Modified Humid Continential with the nearby Atlantic Ocean exerting a considerable influence. Most low pressure weather systems that affect the area either develop in the midwest and move eastward under the influence of the prevailingly westerly flow aloft or form in the southeastern United States and track northward along the east coast. Due to the long overland trajectory cold Canadian high pressure air masses are usually considerable modified by the time they reach this portion of Pennsylvania, picking up warmth from the underlying land and moisture from the Gulf of Mexico and the Atlantic Ocean.
Summers are warm and humid.
Daytime highs generally reach the mid-80s with nighttime lows in the lower 60s. Extented periods of hot and humid weather do occur as the nearby maritime influence produces a fairly uniform weather pattern. On the average 90 degrees is reached on about 22 days each summer. The record high of 105 was set July 4, 1966. The mercury rarely drops much lower then 50 this time of year.
