Washington, D.C., District of Columbia Weather in December

December weather

Washington feels properly wintry in December. Days reach about 8°C, while nights can dip below freezing. Rain falls on several days, and grey skies are common. You'll want indoor plans for damp afternoons, though the National Gallery of Art and Smithsonian museums make easy stops between walks.

The National Mall is still worth seeing, but cold wind can make a long stretch between monuments feel tiring. Save a riverside stroll for a brighter spell, and don't count on a comfortable day at the Tidal Basin. December's short daylight also means less time for outdoor sightseeing.

Holiday lights and crowds

The National Christmas Tree on the Ellipse is a seasonal highlight, and the Downtown Holiday Market brings stalls and snacks near the National Portrait Gallery. Smithsonian's National Zoo also runs its ZooLights event. These draws can make evenings busy, especially around the holidays.

Families who enjoy festive displays will find plenty to do, but the cold can wear younger kids down during long outdoor visits. Museums are a useful warm-up between lights and market stops.

Costs and practical tips

December is generally quieter than the popular spring cherry blossom season, so you'll often find fewer visitors at major sights. The days around Christmas and New Year can still be busy, and holiday travel may push up hotel rates. It's a mixed month: calmer than peak spring, but not uniformly quiet or cheap.

For a practical local move, take the Metro to Smithsonian station for the Mall, then duck into the nearby Smithsonian museums when rain sets in. If you're heading to the National Christmas Tree, remember it's on the Ellipse, south of the White House—not on the Mall. The cold and wet weather make indoor stops more appealing than long outdoor routes.
