How Crowded Is Shiloh National Military Park in September?

September runs about 1× Shiloh National Military Park'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 33,000 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes September the 7th-busiest of the park's twelve months, sitting between the May peak (1.3×) and the December low (0.7×).

On our Best Time to Visit score September rates 60/100 ("Good") — the single best-rated month at Shiloh, balancing crowds against weather and daylight.

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 61°F, with about 4.3" 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 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 9.6-hour midwinter low and the 14.4-hour summer high.

Park-wide, 2025 drew 346,955 recreation visits, down 10.2% from 386,152 in 2024.
