How Crowded Is Clara Barton National Historic Site in March?

March runs about 1.2× Clara Barton National Historic Site's average month, which makes it a busy month here — roughly 10% of the park's yearly visitors come in March.

In a typical March the park sees roughly 1,500 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes March the 5th-busiest of the park's twelve months, sitting between the June peak (1.5×) and the January low (0.4×).

On our Best Time to Visit score March rates 29/100 ("Poor"), versus the top-rated October at 60/100 — best overall balance of crowds, weather and daylight.

Typical March weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 55°F and an overnight low around 34°F, with about 4.2" of precipitation.

That average of about 44°F is cool, so layers and a shorter daylight window matter.

Because June, July and August together draw about 34% of annual visitors, choosing March instead steps outside that summer crush — the single biggest lever on how crowded the park feels.

You'll have about 11.7 hours of daylight in March to explore — between the 9.3-hour midwinter low and the 14.7-hour summer high.

Park-wide, 2025 drew 11,309 recreation visits, down 15.2% from 13,334 in 2024.

Across the past decade overall visitation has eased about 9.5%, so March may feel a touch quieter than it once did.
