Weather in December

December is the beginning of the cold winter in Delaware with short days amid mild sunshine. The interior and northern parts of the state receive higher snowfall than the rest.
The average high temperatures are in the mild 45°F (7.2°C) to 49°F (9.4°C) range, while the average low temperatures lie in the cold 28°F (-2.2°C) to 34°F (1.1°C) zone. Dover, the capital, in the center of the state registers temperatures in the cold range of 31°F (-0.6°C) to 47°F (8.3°C).
The rainfall is to the tune of 3" (76mm) to 4" (102mm) with 10 to 12 wet days in the month. Snowfall is light and rarely crosses 4" (102mm) at the start of the winter. Arctic chills occasionally invade the state that sees a drop in temperatures by a few degrees, especially in the north.
Bring out the sweaters and jackets from the closet for the chilly nights. Christmas is a combination of rain, shine, and cold in December in Delaware, but there is no missing of the festival spirit.
