How Crowded Is San Francisco Maritime National Historical Park in March?

March runs about 0.9× San Francisco Maritime National Historical Park's average month, which makes it a quiet month here — roughly 7% of the park's yearly visitors come in March.

In a typical March the park sees about 228,000 recreation visits, based on National Park Service monthly counts from 1989 to 2025.

That makes March the 8th-busiest of the park's twelve months, sitting between the July peak (1.5×) and the January low (0.7×).

On our Best Time to Visit score March rates 67/100 ("Good"), versus the top-rated November at 69/100 — pleasant weather with noticeably thinner crowds (shoulder season).

Typical March weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 62°F and an overnight low around 49°F, with about 3.2" of precipitation.

That average of about 56°F is a comfortable range for hiking and being outdoors all day.

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 9.4-hour midwinter low and the 14.6-hour summer high.

Park-wide, 2025 drew 2,944,483 recreation visits, up 16.1% from 2,535,134 in 2024.

Across the past decade overall visitation has eased about 31%, so March may feel a touch quieter than it once did.
