How Much Snow Does Baltimore Actually Get Each Winter?

Baltimore receives 10 to 21 inches of snow per winter season on average, with significant year-to-year variation. Most snow falls between December and February, though measurable accumulation occurs only 4 to 8 days per winter. A single storm can bring 4 to 8 inches, but winters with minimal snow are common, and major accumulation (over a foot) happens roughly every other year.

Typical Snow Pattern in Baltimore

Baltimore's winter climate sits in a zone where snow is neither guaranteed nor rare. The city's location on the Atlantic coast creates competing air masses: Arctic systems from the north and Atlantic moisture from the east. When these collide, heavy snow can develop quickly, but many winters bring only light, scattered dustings that melt within days.

The National Weather Service Baltimore/Washington office tracks snowfall at Baltimore-Washington International Airport, the official reference station for the city. Data from 1990 to 2024 shows winters ranging from as little as 2 inches to as much as 29 inches. The median sits near 15 inches, but that average masks the unpredictability: three winters in the past decade brought under 8 inches each, while two brought over 20 inches.

December snow in Baltimore is wet and often brief. January and February are the peak snow months, with February producing the most consistent accumulation. By March, temperatures climb above freezing more often than below it, so snow that does fall typically melts quickly. Snow in April or later is rare but not unprecedented; a measurable snow event occurred in April 2017.

Why Baltimore's Snow Differs from Nearby Areas

Location matters enormously. Baltimore is 10 miles inland from the Chesapeake Bay and sits only 40 feet above sea level on average. Cities northwest of Baltimore, like Frederick or the Shenandoah Valley, sit at higher elevation and latitude and receive 20 to 30 inches of snow annually. Cities south and east, like Richmond or Virginia Beach, receive less. The difference between Baltimore getting 15 inches and Frederick getting 25 inches in the same winter is typical because of elevation and distance from moderating bay and ocean effects.

Nor'easters moving up the Atlantic coast often produce 6 to 12 inches of snow in Baltimore. These storms are common January through March and develop when a low-pressure system hugs the coast. The same storm may produce twice as much snow 50 miles inland (in the Blue Ridge foothills) but less than half in coastal Delaware.

Preparing for Baltimore Winters

Most Baltimore residents experience at least two or three significant snow events per winter, meaning snow removal is a real responsibility if you own a home or driveway. The city's Department of Transportation manages 340 miles of city streets and has salt storage facilities at multiple locations, but residential driveways are private responsibility. Shovel salt or calcium chloride products are sold at hardware stores and big-box retailers throughout the fall and winter; expect to pay $4 to $8 per 50-pound bag.

If a major storm hits Baltimore, schools and businesses often close. The Baltimore City Public Schools system makes closure decisions by 5:30 a.m. on the morning of the storm and communicates them through local media and the school system website. County systems like Baltimore County Public Schools make separate decisions. One 8-inch-plus snowstorm can shut down the city for a day or two while roads are cleared.

Black ice is a genuine hazard in Baltimore winters. Roads that appear wet in the morning can have a thin ice glaze where temperature hovers near 32 degrees Fahrenheit. This is more common in early December and late March when temperatures cross the freezing point frequently during the day.

Comparing Winter Severity

A Baltimore winter with 15 inches of snow is considered average, not severe. The winter of 2009-2010 brought 29 inches and is often cited as the heaviest on recent record. The winter of 2021-2022 brought only 3 inches. To gauge whether an upcoming winter forecast sounds typical for Baltimore, expect 10 to 20 inches to be the normal range; anything below 5 inches is a mild winter, and anything above 25 inches is unusually heavy.

The National Weather Service Baltimore/Washington office issues winter storm watches and warnings when snow becomes likely. These are typically issued 2 to 4 days before a storm arrives.

Related Questions

When is Baltimore's snowiest month? February is typically the snowiest month in Baltimore, followed by January. December snow is frequent but usually light and melts quickly.

Does Baltimore ever get ice storms? Ice storms occur rarely in Baltimore proper, though they are more common in surrounding counties farther inland. When they do occur, they cause significant power outages and road hazards.

How far in advance can the National Weather Service predict Baltimore snowfall? Forecast confidence increases significantly within 3 to 4 days of a storm. More than a week out, snow predictions for Baltimore are highly uncertain due to the precision required for coastal storm tracks.
