How Crowded Is Monocacy National Battlefield in August?

August runs about 1.2× Monocacy National Battlefield's average month, which makes it a busy month here — roughly 10% of the park's yearly visitors come in August.

In a typical August the park sees about 12,000 recreation visits, based on National Park Service monthly counts from 1991 to 2025.

That makes August the 3rd-busiest of the park's twelve months, sitting between the July peak (1.5×) and the January low (0.5×).

On our Best Time to Visit score August rates 52/100 ("Fair"), versus the top-rated April at 56/100 — 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 87°F and an overnight low around 66°F, with about 2.9" of precipitation.

That average of about 77°F is warm enough that midday heat is worth planning around.

August falls inside the park's busiest stretch: June, July and August together pull about 33% of the year's visitors, so a visit this month means sharing the park with the peak-season crowd.

You'll have about 13.5 hours of daylight in August to explore — between the 9.2-hour midwinter low and the 14.8-hour summer high.

Park-wide, 2025 drew 116,902 recreation visits, about flat from 116,520 in 2024.

Across the past decade overall visitation has risen about 7.4%, so a August visit is likely to feel busier than it did a few years ago.
