Roughly 15% of the park's yearly visitors come in September: about 19,000 recreation visits in a typical year, based on National Park Service monthly counts from 2004 to 2025.

On our Best Time to Visit score September rates 61/100 ("Good"). Our recommended month is May: the lightest crowds of the park's good-weather months.

The daily average of about 62°F is a comfortable range for hiking and being outdoors all day. These figures are 1991–2020 NOAA climate normals from the nearest station, about 9.4 miles from the park.

Because June, July and August together draw about 61% 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 12.3 hours of daylight in September to explore — between the 8.7-hour midwinter low and the 15.3-hour summer high.

Park-wide, 2025 drew 102,146 recreation visits, down 13.5% from 118,108 in 2024.

Across the past decade overall visitation has eased about 9.3%, so September may feel a touch quieter than it once did.
