How Crowded Is Vicksburg National Military Park in September?

September runs about 0.9× Vicksburg National Military Park's average month, which makes it an average month here — roughly 7% of the park's yearly visitors come in September.

In a typical September the park sees about 31,000 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes September the 9th-busiest of the park's twelve months, sitting between the June peak (1.3×) and the January low (0.7×).

On our Best Time to Visit score September rates 64/100 ("Good") — the single best-rated month at Vicksburg, balancing crowds against weather and daylight.

Typical September weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 88°F and an overnight low around 67°F, with about 3.7" of precipitation.

That average of about 77°F is warm enough that midday heat is worth planning around.

Because June, July and August together draw about 28% 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 9.9-hour midwinter low and the 14.1-hour summer high.

Park-wide, 2025 drew 410,300 recreation visits, up 1.7% from 403,332 in 2024.

Across the past decade overall visitation has eased about 11.4%, so September may feel a touch quieter than it once did.
