How Crowded Is Eleanor Roosevelt National Historic Site in September?

September runs about 1.7× Eleanor Roosevelt National Historic Site's average month, which makes it a very busy month here — roughly 14% of the park's yearly visitors come in September.

In a typical September the park sees roughly 4,600 recreation visits, based on National Park Service monthly counts from 1985 to 2025.

That makes September the 4th-busiest of the park's twelve months, sitting between the October peak (2.1×) and the January low (0.2×).

On our Best Time to Visit score September rates 50/100 ("Fair"), versus the top-rated May at 64/100 — 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 74°F and an overnight low around 54°F, with about 4.6" of precipitation.

That average of about 64°F is a comfortable range for hiking and being outdoors all day.

Because June, July and August together draw about 41% 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-hour midwinter low and the 15-hour summer high.

Park-wide, 2025 drew 13,586 recreation visits, down 42.7% from 23,699 in 2024.

Across the past decade overall visitation has eased about 64.6%, so September may feel a touch quieter than it once did.
