How Crowded Is Independence National Historical Park in August?

August runs about 1.3× Independence National Historical Park's average month, which makes it a busy month here — roughly 11% of the park's yearly visitors come in August.

In a typical August the park sees about 338,000 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes August the 4th-busiest of the park's twelve months, sitting between the July peak (1.6×) and the January low (0.5×).

On our Best Time to Visit score August rates 48/100 ("Fair"), versus the top-rated October at 55/100 — pleasant weather with noticeably thinner crowds (shoulder season).

Typical August weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 87°F and an overnight low around 70°F, with about 5" of precipitation.

That average of about 78°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 35% of the year's visitors, so a visit this month means sharing the park with the peak-season crowd.

You'll have about 13.6 hours of daylight in August to explore — between the 9.2-hour midwinter low and the 14.8-hour summer high.

Park-wide, 2025 drew 1,926,580 recreation visits, down 31.2% from 2,798,651 in 2024.

Across the past decade overall visitation has eased about 39.9%, so August may feel a touch quieter than it once did.
