How Crowded Is Navajo National Monument in August?

August runs about 1.4× Navajo National Monument's average month, which makes it a busy month here — roughly 12% of the park's yearly visitors come in August.

In a typical August the park sees roughly 6,700 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes August the 3rd-busiest of the park's twelve months, sitting between the September peak (1.5×) and the January low (0.3×).

On our Best Time to Visit score August rates 55/100 ("Fair"), versus the top-rated June at 64/100 — 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 83°F and an overnight low around 58°F, with about 1.5" 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 34% of the year's visitors, so a visit this month means sharing the park with the peak-season crowd.

You'll have about 13.4 hours of daylight in August to explore — between the 9.5-hour midwinter low and the 14.5-hour summer high.

Park-wide, 2024 drew 58,442 recreation visits, up 32.3% from 44,180 in 2023.

Across the past decade overall visitation has eased about 21.8%, so August may feel a touch quieter than it once did.
