How Crowded Is Lincoln Boyhood National Memorial in September?

September runs about 1.3× Lincoln Boyhood National Memorial'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 about 14,000 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 July peak (4.9×) and the January low (0.1×).

On our Best Time to Visit score September rates 75/100 ("Excellent"), versus the top-rated October at 75/100 — 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 82°F and an overnight low around 58°F, with about 3.6" 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 67% 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 9.4-hour midwinter low and the 14.6-hour summer high.

Park-wide, 2025 drew 115,517 recreation visits, down 11.1% from 129,904 in 2024.

Across the past decade overall visitation has eased about 8.9%, so September may feel a touch quieter than it once did.
