How Crowded Is Manzanar National Historic Site in August?

August 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 August.

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

That makes August the 3rd-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 August rates 42/100 ("Poor"), versus the top-rated March at 54/100 — pleasant weather with noticeably thinner crowds (shoulder season).

Typical August weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 101°F and an overnight low around 65°F, with about 0.2" of precipitation.

That average of about 83°F is warm enough that midday heat is worth planning around.

August falls inside the park's busiest stretch: June, July and August together pull about 33% of the year's visitors, so a visit this month means sharing the park with the peak-season crowd.

You'll have about 13.4 hours of daylight in August 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 August visit is likely to feel busier than it did a few years ago.
