How Crowded Is Clara Barton National Historic Site in August?

August runs about 1.4× 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 August.

In a typical August the park sees roughly 1,700 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes August the 3rd-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 August rates 43/100 ("Poor"), versus the top-rated October at 60/100 — best overall balance of crowds, weather and daylight.

Typical August weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 86°F and an overnight low around 66°F, with about 4.4" of precipitation.

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

August 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 13.5 hours of daylight in August to explore — between the 9.3-hour midwinter low and the 14.7-hour summer high.

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 August may feel a touch quieter than it once did.
