How Crowded Is Timpanogos Cave National Monument in August?

August runs about 2.4× Timpanogos Cave National Monument's average month, which makes it a very busy month here — roughly 20% of the park's yearly visitors come in August.

In a typical August the park sees about 22,000 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes August the 2nd-busiest of the park's twelve months, sitting between the July peak (2.9×) and the January low (0×).

On our Best Time to Visit score August rates 55/100 ("Fair"), versus the top-rated September at 63/100 — 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 87°F and an overnight low around 58°F, with about 1.5" of precipitation.

That average of about 72°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 64% 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 9.1-hour midwinter low and the 14.9-hour summer high.

Park-wide, 2025 drew 92,031 recreation visits, down 19.3% from 114,034 in 2024.

Across the past decade overall visitation has risen about 18.8%, so a August visit is likely to feel busier than it did a few years ago.
