How Crowded Is Korean War Veterans Memorial in September?

September runs about 1× Korean War Veterans Memorial'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 293,000 recreation visits, based on National Park Service monthly counts from 1996 to 2025.

That makes September the 8th-busiest of the park's twelve months, sitting between the May peak (1.5×) and the January low (0.4×).

On our Best Time to Visit score September rates 51/100 ("Fair"), versus the top-rated February at 79/100 — the best overall balance of crowds and daylight.

Because June, July and August together draw about 30% 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 9.3-hour midwinter low and the 14.7-hour summer high.

Park-wide, 2025 drew 3,975,010 recreation visits, down 8.5% from 4,344,305 in 2024.

Across the past decade overall visitation has risen about 10.8%, so a September visit is likely to feel busier than it did a few years ago.
