How Crowded Is Frederick Douglass National Historic Site in May?

May 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 May.

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

That makes May the 2nd-busiest of the park's twelve months, sitting between the June peak (1.5×) and the January low (0.4×).

On our Best Time to Visit score May rates 50/100 ("Fair"), versus the top-rated September at 70/100 — pleasant weather with noticeably thinner crowds (shoulder season).

Typical May weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 77°F and an overnight low around 58°F, with about 3.9" of precipitation.

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

Because June, July and August together draw about 33% of annual visitors, choosing May instead steps outside that summer crush — the single biggest lever on how crowded the park feels.

You'll have about 14.1 hours of daylight in May to explore — between the 9.3-hour midwinter low and the 14.7-hour summer high.

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 May visit is likely to feel busier than it did a few years ago.
