Snowfall in Delaware comes in all shapes and sizes across several cities. Average snowfall in Delaware measures between approximately 10 and 20 inches. While temperatures in Delaware aren’t unbearable, winters remain cold and with them come the possibility of snowstorms and heavy snowfall.
Understanding Snowfall in Delaware
Winters in Delaware are cold, but they are not as lengthy as those experienced by neighboring northeastern states. Snowfall in Delaware varies according to the region and is influenced by several factors. For instance, wind currents produced by the Jet Stream carry storms that drop precipitation on Delaware and bring temperature changes. Sometimes, the Jet Steam will experience troughs. Troughs are dips in the Jet Steam that help to create storms along the coast. Other factors, like proximity to the Atlantic Ocean and distance from the equator, also influence snowfall and temperatures in Delaware.
Coastal nor’easters are a type of snowstorm native to the northeast coast of the United States characterized by powerful winds and large amounts of precipitation. These storms develop due to a clash between warm coastal air and cool inland air. Coastal nor’easters can bring snow or rain to Delaware. The rain-snow line in Delaware divides warmer southern areas from cooler northern portions, which contain topography characterized by higher elevations. Therefore, while South Delaware might experience rain from a nor’easter, the northern portion of the state can receive inches upon inches of snowfall. Across New England and the northeast coast of the United States, coastal nor’easters have been known to bring on tremendous amounts of snowfall.

Description of First Snowfalls in Delaware
Snowfall in Delaware is much like snowfall in the rest of the northeast coast of the United States. Snow can be wet or dry depending on elevation, but most snowfall is heavy and packed down in the northeast. February is the driest month in Delaware as well as the snowiest month. Therefore, snow in February is more likely to fall as fresh powder than wet, packed snow cover. Dover, Delaware averages 13.2 inches of snowfall per season. A close second, Greenwood, Delaware receives 12.8 inches of annual snowfall. The least amount of snowfall accumulates in Lewes, Delaware, measuring 10.5 inches. On the contrary, Wilmington, Delaware receives the most snowfall at 20.2 inches. However, all of Delaware averages fall below snowfall averages in most northeastern states.
Biggest Snowfall in Delaware
On February 5th and 6th of 2010, between 21 and 26 inches of snow fell in various cities in Delaware. This snowfall set the record for the largest single snowfall in Delaware. After a few days, even more snow came roaring in, dumping another five to 10 inches on Delaware, according to location. Approximately 86,000 residents lost power, and other states had to help pitch in resources and workers to fix snowfall damages. The National Guard aided Delaware, too. In the end, the snowstorm left $9 million in damages.
Blizzards in Delaware
Although the snowfall in February 2010 was a blizzard of its own (see above), other treacherous snowstorms have threatened Delaware. Some notable blizzards have even dated back over 100 years!
The Great Blizzard of 1888
Also known as The Great White Hurricane, The Great Blizzard of 1888 covered the Northeast United States in an extreme wave of snowfall. Between March 11th and March 14th, anywhere from 20 to 60 inches of snow fell on various states on the east coast, including Delaware. Over 400 people died within the region, and over 200 ships, some on Delaware’s coast, were damaged by the snowfall.
On December 25th and 26th of 1909, almost 24 inches of snow fell throughout the Northeast United States. Although the blizzard brought a white Christmas to Delaware residents, it wasn’t exactly the snowfall that they were hoping for. Many people were trapped, unable to go to work, and inflation on food and other goods skyrocketed.
Christmas Blizzard II
Exactly 100 years after the Christmas Blizzard of 1909, another snowstorm attacked Delaware residents. In 2009, over 12 inches of snow fell in Delaware, causing yet another extreme white Christmas. At least this time, the snow wasn’t as abundant as the first Christmas Blizzard, meaning that families could enjoy a Christmas winter wonderland.
The Blizzard of 1996
The Blizzard of 1996 dumped inches upon inches of snow onto Delaware and the Northeast United States. Coastal Delaware was faced with abundant precipitation and flooding rather than snow. Many areas within the state were challenged by the extreme snowfall, with beaches on the coast suffering the most.
