How Crowded Is George Washington Carver National Monument in September?

September runs about 1.3× George Washington Carver National Monument's average month, which makes it a busy month here — roughly 11% of the park's yearly visitors come in September.

In a typical September the park sees roughly 4,200 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes September the 3rd-busiest of the park's twelve months, sitting between the April peak (1.5×) and the January low (0.3×).

On our Best Time to Visit score September rates 49/100 ("Fair"), versus the top-rated August at 60/100 — 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 83°F and an overnight low around 57°F, with about 4.5" 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 27% 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 39,081 recreation visits, up 4.8% from 37,282 in 2023.

Across the past decade overall visitation has eased about 29.4%, so September may feel a touch quieter than it once did.
