10 Sep
Summary
- First frost is anticipated between late October and mid-November.
- Measurable snowfall in Wilmington has a mean date of December 15.
- Winter forecasts vary, predicting mixed precipitation or heavy snow.
As Delaware experiences late-summer warmth, attention turns to upcoming winter weather. The Farmers' Almanac projects the first frost could occur between late October and mid-November. For snowfall, the almanac suggests conditions favorable for snow historically begin in late November, with a prediction of first snow in late November or December.
State climatologist Kevin Brinson notes that while specific first frost data isn't available, the average first freeze in New Castle and Kent counties is around November 2, and November 3 in Sussex County. In Wilmington, the average date for at least 0.1 inch of snowfall is December 15.
Winter forecasts vary, with the Farmers' Almanac anticipating a complex pattern. Coastal areas might receive more rain or mixed precipitation, whereas inland areas could face significant heavy, wet snow in January and February. The Old Farmer's Almanac, however, forecasts a milder winter with above-average temperatures and slightly below-normal snowfall and precipitation, with the coldest periods in December, January, and February.
