How Crowded Is Minuteman Missile National Historic Site in August?

August runs about 2.1× Minuteman Missile National Historic Site's average month, which makes it a very busy month here — roughly 18% of the park's yearly visitors come in August.

In a typical August the park sees about 21,000 recreation visits, based on National Park Service monthly counts from 2004 to 2025.

That makes August the 3rd-busiest of the park's twelve months, sitting between the July peak (3×) and the February low (0.1×).

On our Best Time to Visit score August rates 62/100 ("Good"), versus the top-rated May at 65/100 — best overall balance of crowds, weather and daylight.

Typical August weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 88°F and an overnight low around 56°F, with about 1.6" of precipitation.

That average of about 72°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 61% of the year's visitors, so a visit this month means sharing the park with the peak-season crowd.

You'll have about 13.8 hours of daylight in August to explore — between the 8.7-hour midwinter low and the 15.3-hour summer high.

Park-wide, 2025 drew 102,146 recreation visits, down 13.5% from 118,108 in 2024.

Across the past decade overall visitation has eased about 9.3%, so August may feel a touch quieter than it once did.
