How Crowded Is Chickasaw National Recreation Area in September?

September runs about 1.1× Chickasaw National Recreation Area'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 about 149,000 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 (2.1×) and the December low (0.4×).

On our Best Time to Visit score September rates 63/100 ("Good"), versus the top-rated October at 74/100 — 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 86°F and an overnight low around 62°F, with about 4.4" of precipitation.

That average of about 74°F is a comfortable range for hiking and being outdoors all day.

Because June, July and August together draw about 47% 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 9.7-hour midwinter low and the 14.3-hour summer high.

Park-wide, 2025 drew 1,877,797 recreation visits, up 12.4% from 1,670,498 in 2024.

Across the past decade overall visitation has risen about 15.3%, so a September visit is likely to feel busier than it did a few years ago.
