How Crowded Is African Burial Ground National Monument in September?

September runs about 0.9× African Burial Ground National Monument's average month, which makes it an average month here — roughly 8% of the park's yearly visitors come in September.

In a typical September the park sees roughly 3,100 recreation visits, based on National Park Service monthly counts from 2010 to 2025.

That makes September the 7th-busiest of the park's twelve months, sitting between the October peak (1.6×) and the January low (0.3×).

On our Best Time to Visit score September rates 66/100 ("Good") — the single best-rated month at African Burial Ground, balancing crowds against weather and daylight.

Typical September weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 76°F and an overnight low around 62°F, with about 4.3" of precipitation.

That average of about 69°F is a comfortable range for hiking and being outdoors all day.

Because June, July and August together draw about 34% 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 12.3 hours of daylight in September to explore — between the 9.1-hour midwinter low and the 14.9-hour summer high.

Park-wide, 2024 drew 36,007 recreation visits, down 11.8% from 40,817 in 2023.

Across the past decade overall visitation has eased about 33.7%, so September may feel a touch quieter than it once did.
