How Crowded Is Fort McHenry National Monument and Historic Shrine in June?

June runs about 1.4× Fort McHenry National Monument and Historic Shrine'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 about 55,000 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 (1.4×) and the January low (0.3×).

On our Best Time to Visit score June rates 44/100 ("Poor"), versus the top-rated October at 49/100 — 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 3.4" of precipitation.

That average of about 77°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 35% of the year's visitors, so a visit this month means sharing the park with the peak-season crowd.

You'll have about 14.8 hours of daylight in June to explore — near the year-round maximum.

Park-wide, 2024 drew 394,175 recreation visits, down 8.3% from 429,967 in 2023.

Across the past decade overall visitation has eased about 47.4%, so June may feel a touch quieter than it once did.
