How Crowded Is Clara Barton National Historic Site in June?

June runs about 1.5× Clara Barton 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 1,900 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

It is the single busiest month of the year at Clara Barton; January, the quietest, runs only about 0.4× the average — a 4-to-1 swing between high and low season.

On our Best Time to Visit score June rates 46/100 ("Fair"), versus the top-rated October at 60/100 — best overall balance of crowds, weather and daylight.

Typical June weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 84°F and an overnight low around 63°F, with about 4.2" of precipitation.

That average of about 73°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 34% 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, 2025 drew 11,309 recreation visits, down 15.2% from 13,334 in 2024.

Across the past decade overall visitation has eased about 9.5%, so June may feel a touch quieter than it once did.
