How Crowded Is Chiricahua National Monument in September?

September runs about 0.6× Chiricahua National Monument's average month, which makes it a quiet month here — roughly 5% of the park's yearly visitors come in September.

In a typical September the park sees roughly 3,100 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes September the 9th-busiest of the park's twelve months, sitting between the March peak (2.2×) and the August low (0.5×).

On our Best Time to Visit score September rates 84/100 ("Excellent"), versus the top-rated August at 82/100 — pleasant weather with noticeably thinner crowds (shoulder season).

Typical September weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 84°F and an overnight low around 57°F, with about 1.6" of precipitation.

That average of about 70°F is a comfortable range for hiking and being outdoors all day.

Because June, July and August together draw about 13% of annual visitors, choosing September instead steps outside that summer crush — the single biggest lever on how crowded the park feels.

You'll have about 12.2 hours of daylight in September to explore — between the 9.9-hour midwinter low and the 14.1-hour summer high.

Park-wide, 2025 drew 70,406 recreation visits, down 1.4% from 71,390 in 2024.

Across the past decade overall visitation has risen about 13.8%, so a September visit is likely to feel busier than it did a few years ago.
