How Crowded Is Frederick Douglass National Historic Site in June?

June runs about 1.5× Frederick Douglass National Historic Site's average month, which makes it a busy month here — roughly 12% of the park's yearly visitors come in June.

In a typical June the park sees roughly 6,700 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

It is the single busiest month of the year at Frederick Douglass; January, the quietest, runs only about 0.4× the average — a 3-to-1 swing between high and low season.

On our Best Time to Visit score June rates 42/100 ("Poor"), versus the top-rated September at 70/100 — 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 85°F and an overnight low around 68°F, with about 4.2" of precipitation.

That average of about 76°F is warm enough that midday heat is worth planning around.

June 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 14.7 hours of daylight in June to explore — near the year-round maximum.

Park-wide, 2024 drew 25,836 recreation visits, down 57.7% from 61,063 in 2019.

Across the past decade overall visitation has risen about 22.2%, so a June visit is likely to feel busier than it did a few years ago.
