How Crowded Is Fort Point National Historic Site in September?

September runs about 0.9× Fort Point National Historic Site's average month, which makes it an average month here — roughly 8% of the park's yearly visitors come in September.

In a typical September the park sees about 98,000 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes September the 8th-busiest of the park's twelve months, sitting between the August peak (1.6×) and the January low (0.6×).

On our Best Time to Visit score September rates 73/100 ("Good"), versus the top-rated November at 66/100 — 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 70°F and an overnight low around 56°F, with about 0.1" of precipitation.

That average of about 63°F is a comfortable range for hiking and being outdoors all day.

Because June, July and August together draw about 35% 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 9.4-hour midwinter low and the 14.6-hour summer high.

Park-wide, 2025 drew 1,010,870 recreation visits, down 15% from 1,189,908 in 2024.

Across the past decade overall visitation has eased about 33.3%, so September may feel a touch quieter than it once did.
