How Crowded Is National Park of American Samoa in September?

September runs about 1× National Park of American Samoa'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 roughly 2,300 recreation visits, based on National Park Service monthly counts from 2002 to 2025.

That makes September the 5th-busiest of the park's twelve months, sitting between the October peak (1.5×) and the June low (0.7×).

On our Best Time to Visit score September rates 55/100 ("Fair"), versus the top-rated June at 84/100 — the best overall balance of crowds and daylight.

Because June, July and August together draw about 19% 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 11.9 hours of daylight in September to explore — between the 11.2-hour midwinter low and the 12.8-hour summer high.

Park-wide, 2024 drew 22,567 recreation visits, up 86% from 12,135 in 2023.

Across the past decade overall visitation has eased about 30.2%, so September may feel a touch quieter than it once did.
