How Crowded Is Montezuma Castle National Monument in August?

August runs about 0.7× Montezuma Castle National Monument's average month, which makes it a quiet month here — roughly 6% of the park's yearly visitors come in August.

In a typical August the park sees about 23,000 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes August the 10th-busiest of the park's twelve months, sitting between the March peak (1.6×) and the January low (0.7×).

On our Best Time to Visit score August rates 75/100 ("Excellent") — the single best-rated month at Montezuma Castle, balancing crowds against weather and daylight.

Typical August weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 99°F and an overnight low around 63°F, with about 2.1" of precipitation.

That average of about 81°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 21% of the year's visitors, so a visit this month means sharing the park with the peak-season crowd.

You'll have about 13.3 hours of daylight in August to explore — between the 9.7-hour midwinter low and the 14.3-hour summer high.

Park-wide, 2024 drew 379,967 recreation visits, up 3.5% from 367,239 in 2023.
