How Crowded Is Minidoka National Historic Site in August?

August runs about 2.2× Minidoka National Historic Site's average month, which makes it a very busy month here — roughly 18% of the park's yearly visitors come in August.

In a typical August the park sees roughly 3,100 recreation visits, based on National Park Service monthly counts from 2017 to 2025.

That makes August the 3rd-busiest of the park's twelve months, sitting between the July peak (2.6×) and the December low (0.1×).

On our Best Time to Visit score August rates 59/100 ("Fair"), versus the top-rated September at 65/100 — 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 88°F and an overnight low around 54°F, with about 0.3" of precipitation.

That average of about 71°F is a comfortable range for hiking and being outdoors all day.

August falls inside the park's busiest stretch: June, July and August together pull about 58% of the year's visitors, so a visit this month means sharing the park with the peak-season crowd.

You'll have about 13.7 hours of daylight in August to explore — between the 8.9-hour midwinter low and the 15.1-hour summer high.

Park-wide, 2025 drew 43,539 recreation visits, up 137.2% from 18,358 in 2023.

Across the past decade overall visitation has risen about 68%, so a August visit is likely to feel busier than it did a few years ago.
