How Crowded Is World War II Memorial in December?

December runs about 0.6× World War II Memorial's average month, which makes it a quiet month here — roughly 5% of the park's yearly visitors come in December.

In a typical December the park sees about 231,000 recreation visits, based on National Park Service monthly counts from 2004 to 2025.

That makes December the 10th-busiest of the park's twelve months, sitting between the May peak (1.5×) and the January low (0.4×).

On our Best Time to Visit score December rates 41/100 ("Poor"), versus the top-rated September at 59/100 — 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 31% 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 3,993,717 recreation visits, down 22.6% from 5,160,769 in 2024.

Across the past decade overall visitation has risen about 7.9%, so a December visit is likely to feel busier than it did a few years ago.
