How Crowded Is Capulin Volcano National Monument in September?

September runs about 1× Capulin Volcano National Monument's average month, which makes it an average month here — roughly 9% of the park's yearly visitors come in September.

In a typical September the park sees roughly 6,400 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes September the 5th-busiest of the park's twelve months, sitting between the July peak (2.7×) and the January low (0.3×).

On our Best Time to Visit score September rates 70/100 ("Good"), versus the top-rated August at 71/100 — best overall balance of crowds, weather and daylight.

Typical September weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 77°F and an overnight low around 46°F, with about 1.9" of precipitation.

That average of about 62°F is a comfortable range for hiking and being outdoors all day.

Because June, July and August together draw about 52% 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 9.5-hour midwinter low and the 14.5-hour summer high.

Park-wide, 2024 drew 96,078 recreation visits, up 8.5% from 88,514 in 2023.

Across the past decade overall visitation has risen about 40.4%, so a September visit is likely to feel busier than it did a few years ago.
