How Crowded Is Manzanar National Historic Site in May?

May runs about 1.3× Manzanar National Historic Site's average month, which makes it a busy month here — roughly 11% of the park's yearly visitors come in May.

In a typical May the park sees about 11,000 recreation visits, based on National Park Service monthly counts from 2000 to 2025.

That makes May the 4th-busiest of the park's twelve months, sitting between the July peak (1.4×) and the January low (0.5×).

On our Best Time to Visit score May rates 60/100 ("Good"), versus the top-rated March at 54/100 — pleasant weather with noticeably thinner crowds (shoulder season).

Typical May weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 85°F and an overnight low around 53°F, with about 0.1" of precipitation.

That average of about 69°F is a comfortable range for hiking and being outdoors all day.

Because June, July and August together draw about 33% of annual visitors, choosing May instead steps outside that summer crush — the single biggest lever on how crowded the park feels.

You'll have about 14 hours of daylight in May to explore — between the 9.5-hour midwinter low and the 14.5-hour summer high.

Park-wide, 2025 drew 95,764 recreation visits, up 2% from 93,854 in 2024.

Across the past decade overall visitation has risen about 8.7%, so a May visit is likely to feel busier than it did a few years ago.
