How Crowded Is Fort Sumter and Fort Moultrie National Historical Park in July?

July runs about 1.5× Fort Sumter and Fort Moultrie National Historical Park's average month, which makes it a busy month here — roughly 13% of the park's yearly visitors come in July.

In a typical July the park sees about 79,000 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

It is the single busiest month of the year at Fort Sumter and Fort Moultrie; January, the quietest, runs only about 0.5× the average — a 3-to-1 swing between high and low season.

On our Best Time to Visit score July rates 32/100 ("Poor"), versus the top-rated September at 68/100 — pleasant weather with noticeably thinner crowds (shoulder season).

Typical July weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 91°F and an overnight low around 73°F, with about 6" of precipitation.

That average of about 82°F is warm enough that midday heat is worth planning around.

July falls inside the park's busiest stretch: June, July and August together pull about 34% of the year's visitors, so a visit this month means sharing the park with the peak-season crowd.

You'll have about 14 hours of daylight in July to explore — near the year-round maximum.

Park-wide, 2025 drew 814,658 recreation visits, up 112% from 384,308 in 2024.

Across the past decade overall visitation has eased about 39.7%, so July may feel a touch quieter than it once did.
