How Crowded Is Big Cypress National Preserve in September?

September runs about 0.6× Big Cypress National Preserve's average month, which makes it a quiet month here — roughly 5% of the park's yearly visitors come in September.

In a typical September the park sees about 89,000 recreation visits, based on National Park Service monthly counts from 1989 to 2025.

It is the quietest month of the year at Big Cypress; by contrast February, the busiest, runs about 1.6× the average — so September is the easiest time to have the place largely to yourself.

On our Best Time to Visit score September rates 64/100 ("Good"), versus the top-rated November at 67/100 — pleasant weather with noticeably thinner crowds (shoulder season).

Typical September weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 92°F and an overnight low around 76°F, with about 8.1" of precipitation.

That average of about 84°F is warm enough that midday heat is worth planning around.

Because June, July and August together draw about 17% 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 10.4-hour midwinter low and the 13.6-hour summer high.

Park-wide, 2025 drew 2,262,731 recreation visits, up 2.1% from 2,216,708 in 2024.

Across the past decade overall visitation has risen about 135.4%, so a September visit is likely to feel busier than it did a few years ago.
