How Crowded Is Thaddeus Kosciuszko National Memorial in July?

July runs about 1.8× Thaddeus Kosciuszko National Memorial's average month, which makes it a very busy month here — roughly 15% of the park's yearly visitors come in July.

In a typical July the park sees about 740 recreation visits, based on National Park Service monthly counts from 1981 to 2025.

It is the single busiest month of the year at Thaddeus Kosciuszko; January, the quietest, runs only about 0.4× the average — a 5-to-1 swing between high and low season.

On our Best Time to Visit score July rates 37/100 ("Poor"), versus the top-rated October at 55/100 — 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 89°F and an overnight low around 71°F, with about 4.8" of precipitation.

That average of about 80°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 39% of the year's visitors, so a visit this month means sharing the park with the peak-season crowd.

You'll have about 14.6 hours of daylight in July to explore — near the year-round maximum.

Park-wide, 2013 drew 1,682 recreation visits, down 17.8% from 2,045 in 2012.

Across the past decade overall visitation has eased about 49%, so July may feel a touch quieter than it once did.
