How Crowded Is Lake Mead National Recreation Area in December?

December runs about 0.7× Lake Mead National Recreation Area's average month, which makes it a quiet month here — roughly 6% of the park's yearly visitors come in December.

In a typical December the park sees about 409,000 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

It is the quietest month of the year at Lake Mead; by contrast June, the busiest, runs about 1.3× the average — so December is the easiest time to have the place largely to yourself.

On our Best Time to Visit score December rates 64/100 ("Good"), versus the top-rated November 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 58°F and an overnight low around 37°F, with about 0.5" of precipitation.

That average of about 48°F is cool, so layers and a shorter daylight window matter.

Because June, July and August together draw about 30% 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 9.6 hours of daylight in December to explore — near the year-round minimum.

Park-wide, 2025 drew 6,135,586 recreation visits, down 4.3% from 6,412,854 in 2024.

Across the past decade overall visitation has eased about 17.4%, so December may feel a touch quieter than it once did.
