How Crowded Is Lowell National Historical Park in August?

August runs about 1.5× Lowell National Historical Park's average month, which makes it a busy month here — roughly 12% of the park's yearly visitors come in August.

In a typical August the park sees about 48,000 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes August the 2nd-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 August rates 76/100 ("Excellent"), versus the top-rated September at 81/100 — pleasant weather with noticeably thinner crowds (shoulder season).

Typical August weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 83°F and an overnight low around 59°F, with about 4" of precipitation.

That average of about 71°F is a comfortable range for hiking and being outdoors all day.

August falls inside the park's busiest stretch: June, July and August together pull about 60% of the year's visitors, so a visit this month means sharing the park with the peak-season crowd.

You'll have about 13.7 hours of daylight in August 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 August may feel a touch quieter than it once did.
