How Crowded Is Lowell National Historical Park in June?

June runs about 0.9× Lowell National Historical Park's average month, which makes it an average month here — roughly 8% of the park's yearly visitors come in June.

In a typical June the park sees about 29,000 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes June the 3rd-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 June rates 85/100 ("Excellent"), versus the top-rated September at 81/100 — pleasant weather with noticeably thinner crowds (shoulder season).

Typical June weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 79°F and an overnight low around 55°F, with about 4.4" of precipitation.

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

June 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 15.1 hours of daylight in June to explore — near the year-round maximum.

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 June may feel a touch quieter than it once did.
