How Crowded Is Yukon - Charley Rivers National Preserve in September?

September runs about 1.1× Yukon - Charley Rivers National Preserve's average month, which makes it an average month here — roughly 9% of the park's yearly visitors come in September.

In a typical September the park sees about 510 recreation visits, based on National Park Service monthly counts from 1982 to 2025.

That makes September the 4th-busiest of the park's twelve months, sitting between the August peak (3.4×) and the November low (0.1×).

On our Best Time to Visit score September rates 47/100 ("Fair"), versus the top-rated May at 63/100 — 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 54°F and an overnight low around 31°F, with about 1.3" of precipitation and roughly 2" of snow.

That average of about 43°F is cool, so layers and a shorter daylight window matter.

Because June, July and August together draw about 75% 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 12.6 hours of daylight in September to explore — between the 2.9-hour midwinter low and the 21.1-hour summer high.

Park-wide, 2018 drew 1,272 recreation visits, up 12.3% from 1,133 in 2015.

Across the past decade overall visitation has eased about 80.2%, so September may feel a touch quieter than it once did.
