How Crowded Is Zion National Park in August?

August runs about 1.3× Zion National Park'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 476,000 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes August the 5th-busiest of the park's twelve months, sitting between the June peak (1.5×) and the January low (0.3×).

On our Best Time to Visit score August rates 43/100 ("Poor"), versus the top-rated April 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 98°F and an overnight low around 69°F, with about 1.6" 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 35% 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 9.4-hour midwinter low and the 14.6-hour summer high.

Park-wide, 2025 drew 4,984,525 recreation visits, up 0.8% from 4,946,592 in 2024.

Across the past decade overall visitation has risen about 14.6%, so a August visit is likely to feel busier than it did a few years ago.
