How Crowded Is Johnstown Flood National Memorial in June?

June runs about 1× Johnstown Flood National Memorial's average month, which makes it an average month here — roughly 9% of the park's yearly visitors come in June.

In a typical June the park sees about 13,000 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes June the 6th-busiest of the park's twelve months, sitting between the July peak (1.8×) and the January low (0.1×).

On our Best Time to Visit score June rates 68/100 ("Good") — the single best-rated month at Johnstown Flood, balancing crowds against weather and daylight.

Typical June weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 75°F and an overnight low around 57°F, with about 4.4" of precipitation.

That average of about 66°F is a comfortable range for hiking and being outdoors all day.

June falls inside the park's busiest stretch: June, July and August together pull about 38% of the year's visitors, so a visit this month means sharing the park with the peak-season crowd.

You'll have about 14.9 hours of daylight in June to explore — near the year-round maximum.

Park-wide, 2025 drew 74,977 recreation visits, down 21.8% from 95,842 in 2024.

Across the past decade overall visitation has eased about 23.5%, so June may feel a touch quieter than it once did.
