How Crowded Is New Bedford Whaling National Historical Park in September?

September runs about 1.1× New Bedford Whaling National Historical Park'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 about 11,000 recreation visits, based on National Park Service monthly counts from 1998 to 2025.

That makes September the 4th-busiest of the park's twelve months, sitting between the July peak (2.9×) and the January low (0.3×).

On our Best Time to Visit score September rates 74/100 ("Good"), versus the top-rated May at 71/100 — 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 75°F and an overnight low around 59°F, with about 4.2" of precipitation.

That average of about 67°F is a comfortable range for hiking and being outdoors all day.

Because June, July and August together draw about 49% 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, 2024 drew 18,330 recreation visits, up 7.6% from 17,034 in 2023.

Across the past decade overall visitation has eased about 78.4%, so September may feel a touch quieter than it once did.
