On our Best Time to Visit score September rates 56/100 ("Fair"). Our recommended month is January: the lightest crowds of the park's good-weather months.
The daily average of about 84°F is warm enough that midday heat is worth planning around. These figures are 1991–2020 NOAA climate normals from the nearest station, about 15.6 miles from the park.
Because June, July and August together draw about 24% 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 12.1 hours of daylight in September to explore — between the 10.9-hour midwinter low and the 13.1-hour summer high.
Park-wide, 2025 drew 471,074 recreation visits, up 11.4% from 423,029 in 2024.
Across the past decade overall visitation has risen about 15.5%, so a September visit is likely to feel busier than it did a few years ago.
