How Crowded Is César E. Chávez National Monument in December?

December runs about 0.7× César E. Chávez National Monument'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 870 recreation visits, based on National Park Service monthly counts from 2013 to 2025.

It is the quietest month of the year at César E. Chávez; by contrast April, 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 54/100 ("Fair"), versus the top-rated August at 75/100 — 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 51°F and an overnight low around 31°F, with about 2.1" of precipitation.

That average of about 41°F is cool, so layers and a shorter daylight window matter.

Because June, July and August together draw about 26% 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 31,497 recreation visits, up 18.2% from 26,641 in 2024.

Across the past decade overall visitation has risen about 47.1%, so a December visit is likely to feel busier than it did a few years ago.
