How Crowded Is Joshua Tree National Park in August?

August runs about 0.6× Joshua Tree National Park's average month, which makes it a quiet month here — roughly 5% of the park's yearly visitors come in August.

In a typical August the park sees about 136,000 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes August the 11th-busiest of the park's twelve months, sitting between the March peak (1.6×) and the July low (0.6×).

On our Best Time to Visit score August rates 69/100 ("Good"), versus the top-rated September at 72/100 — 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 103°F and an overnight low around 76°F, with about 0.7" of precipitation.

That average of about 90°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 15% of the year's visitors, so a visit this month means sharing the park with the peak-season crowd.

You'll have about 13.3 hours of daylight in August to explore — between the 9.8-hour midwinter low and the 14.2-hour summer high.

Park-wide, 2025 drew 2,932,644 recreation visits, down 2% from 2,991,874 in 2024.

Across the past decade overall visitation has risen about 15%, so a August visit is likely to feel busier than it did a few years ago.
