How Crowded Is Martin Luther King, Jr. Memorial in December?

December runs about 0.5× Martin Luther King, Jr. Memorial's average month, which makes it a very quiet month here — roughly 4% of the park's yearly visitors come in December.

In a typical December the park sees about 118,000 recreation visits, based on National Park Service monthly counts from 2011 to 2025.

It is the quietest month of the year at Martin Luther King, Jr. Memorial; by contrast March, the busiest, runs about 1.6× the average — so December is the easiest time to have the place largely to yourself.

On our Best Time to Visit score December rates 50/100 ("Fair"), versus the top-rated September at 69/100 — pleasant weather with noticeably thinner crowds (shoulder season).

Typical December weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 49°F and an overnight low around 35°F, with about 3.4" of precipitation and roughly 2" of snow.

That average of about 42°F is cool, so layers and a shorter daylight window matter.

Because June, July and August together draw about 29% of annual visitors, choosing December instead steps outside that summer crush — the single biggest lever on how crowded the park feels.

You'll have about 9.3 hours of daylight in December to explore — near the year-round minimum.

Park-wide, 2025 drew 2,843,263 recreation visits, down 12.6% from 3,251,594 in 2024.
