How Crowded Is Casa Grande Ruins National Monument in January?

January runs about 1.4× Casa Grande Ruins National Monument's average month, which makes it a busy month here — roughly 11% of the park's yearly visitors come in January.

In a typical January the park sees roughly 8,700 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes January the 3rd-busiest of the park's twelve months, sitting between the March peak (2.2×) and the August low (0.4×).

On our Best Time to Visit score January rates 48/100 ("Fair"), versus the top-rated May at 78/100 — pleasant weather with noticeably thinner crowds (shoulder season).

Typical January weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 68°F and an overnight low around 37°F, with about 1" of precipitation.

That average of about 52°F is a comfortable range for hiking and being outdoors all day.

Because June, July and August together draw about 12% of annual visitors, choosing January instead steps outside that summer crush — the single biggest lever on how crowded the park feels.

You'll have about 10 hours of daylight in January to explore — near the year-round minimum.

Park-wide, 2024 drew 104,429 recreation visits, down 6.3% from 111,392 in 2023.
