How Crowded Is Lowell National Historical Park in October?

October runs about 0.5× Lowell National Historical Park's average month, which makes it a quiet month here — roughly 5% of the park's yearly visitors come in October.

In a typical October the park sees about 18,000 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes October the 8th-busiest of the park's twelve months, sitting between the July peak (4.8×) and the December low (0.3×).

On our Best Time to Visit score October rates 61/100 ("Good"), versus the top-rated September at 81/100 — pleasant weather with noticeably thinner crowds (shoulder season).

Typical October weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 62°F and an overnight low around 40°F, with about 5" of precipitation.

That average of about 51°F is a comfortable range for hiking and being outdoors all day.

Because June, July and August together draw about 60% of annual visitors, choosing October instead steps outside that summer crush — the single biggest lever on how crowded the park feels.

You'll have about 10.8 hours of daylight in October to explore — between the 8.9-hour midwinter low and the 15.1-hour summer high.

Park-wide, 2024 drew 264,456 recreation visits, up 3.2% from 256,303 in 2023.

Across the past decade overall visitation has eased about 52.5%, so October may feel a touch quieter than it once did.
