How Crowded Is Hamilton Grange National Memorial in July?

July runs about 1.3× Hamilton Grange National Memorial's average month, which makes it a busy month here — roughly 11% of the park's yearly visitors come in July.

In a typical July the park sees roughly 6,100 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

It is the single busiest month of the year at Hamilton Grange; January, the quietest, runs only about 0.5× the average — a 3-to-1 swing between high and low season.

On our Best Time to Visit score July rates 40/100 ("Poor"), versus the top-rated September at 67/100 — pleasant weather with noticeably thinner crowds (shoulder season).

Typical July weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 85°F and an overnight low around 70°F, with about 4.6" of precipitation.

That average of about 78°F is warm enough that midday heat is worth planning around.

July falls inside the park's busiest stretch: June, July and August together pull about 31% 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 July to explore — near the year-round maximum.

Park-wide, 2024 drew 63,647 recreation visits, up 30.8% from 48,674 in 2023.

Across the past decade overall visitation has eased about 12.2%, so July may feel a touch quieter than it once did.
