How Crowded Is John Fitzgerald Kennedy National Historic Site in September?

September runs about 1.2× John Fitzgerald Kennedy National Historic Site's average month, which makes it a busy month here — roughly 10% of the park's yearly visitors come in September.

In a typical September the park sees roughly 2,300 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 October peak (3.4×) and the January low (0.1×).

On our Best Time to Visit score September rates 62/100 ("Good"), versus the top-rated April at 85/100 — the best overall balance of crowds and daylight.

Because June, July and August together draw about 44% 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 8.9-hour midwinter low and the 15.1-hour summer high.

Park-wide, 2024 drew 18,180 recreation visits, down 26.8% from 24,838 in 2019.

Across the past decade overall visitation has risen about 19.2%, so a September visit is likely to feel busier than it did a few years ago.
