How Crowded Is Navajo National Monument in September?

September runs about 1.5× Navajo National Monument's average month, which makes it a busy month here — roughly 13% of the park's yearly visitors come in September.

In a typical September the park sees roughly 7,500 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

It is the single busiest month of the year at Navajo; January, the quietest, runs only about 0.3× the average — a 6-to-1 swing between high and low season.

On our Best Time to Visit score September rates 47/100 ("Fair"), versus the top-rated June at 64/100 — best overall balance of crowds, weather and daylight.

Typical September weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 76°F and an overnight low around 52°F, with about 1.2" of precipitation.

That average of about 64°F is a comfortable range for hiking and being outdoors all day.

Because June, July and August together draw about 34% of annual visitors, choosing September instead steps outside that summer crush — the single biggest lever on how crowded the park feels.

You'll have about 12.2 hours of daylight in September 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 September may feel a touch quieter than it once did.
