How Crowded Is Ste. Geneviève National Historical Park in August?

August runs about 1.7× Ste. Geneviève National Historical Park's average month, which makes it a very busy month here — roughly 14% of the park's yearly visitors come in August.

In a typical August the park sees roughly 2,900 recreation visits, based on National Park Service monthly counts from 2024 to 2025.

It is the single busiest month of the year at Ste. Geneviève; January, the quietest, runs only about 0.2× the average — a 9-to-1 swing between high and low season.

On our Best Time to Visit score August rates 41/100 ("Poor"), versus the top-rated October at 56/100 — 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 88°F and an overnight low around 66°F, with about 3.3" of precipitation.

That average of about 77°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 13.5 hours of daylight in August to explore — between the 9.4-hour midwinter low and the 14.6-hour summer high.

Park-wide, 2025 drew 16,525 recreation visits, down 30.8% from 23,893 in 2024.
