How Crowded Is Longfellow House Washington's Headquarters National Historic Site in August?

August runs about 1.6× Longfellow House Washington's Headquarters National Historic Site's average month, which makes it a busy month here — roughly 13% of the park's yearly visitors come in August.

In a typical August the park sees roughly 6,700 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes August the 3rd-busiest of the park's twelve months, sitting between the June peak (1.6×) and the January low (0.3×).

On our Best Time to Visit score August rates 24/100 ("Poor"), versus the top-rated February at 79/100 — the best overall balance of crowds and daylight.

August falls inside the park's busiest stretch: June, July and August together pull about 40% of the year's visitors, so a visit this month means sharing the park with the peak-season crowd.

You'll have about 13.7 hours of daylight in August to explore — between the 8.9-hour midwinter low and the 15.1-hour summer high.

Park-wide, 2025 drew 54,912 recreation visits, up 6.6% from 51,496 in 2024.

Across the past decade overall visitation has risen about 9.5%, so a August visit is likely to feel busier than it did a few years ago.
