How Crowded Is Petroglyph National Monument in July?

July runs about 0.9× Petroglyph National Monument's average month, which makes it a quiet month here — roughly 7% of the park's yearly visitors come in July.

In a typical July the park sees about 20,000 recreation visits, based on National Park Service monthly counts from 1992 to 2025.

That makes July the 9th-busiest of the park's twelve months, sitting between the October peak (1.4×) and the August low (0.8×).

On our Best Time to Visit score July rates 76/100 ("Excellent"), versus the top-rated August at 83/100 — 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 93°F and an overnight low around 65°F, with about 1.5" of precipitation.

That average of about 79°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 21% of the year's visitors, so a visit this month means sharing the park with the peak-season crowd.

You'll have about 14.1 hours of daylight in July to explore — between the 9.6-hour midwinter low and the 14.4-hour summer high.

Park-wide, 2025 drew 310,672 recreation visits, down 12.4% from 354,534 in 2024.

Across the past decade overall visitation has risen about 42%, so a July visit is likely to feel busier than it did a few years ago.
