How Crowded Is Aniakchak National Monument & Preserve in August?

August runs about 3.4× Aniakchak National Monument & Preserve's average month, which makes it a very busy month here — roughly 28% of the park's yearly visitors come in August.

In a typical August the park sees about 360 recreation visits, based on National Park Service monthly counts from 1989 to 2025.

That makes August the 2nd-busiest of the park's twelve months, sitting between the September peak (3.7×) and the February low (0.1×).

On our Best Time to Visit score August rates 38/100 ("Poor"), versus the top-rated June at 67/100 — best overall balance of crowds, weather and daylight.

Typical August weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 61°F and an overnight low around 45°F, with about 4.4" of precipitation.

That average of about 53°F is a comfortable range for hiking and being outdoors all day.

August falls inside the park's busiest stretch: June, July and August together pull about 49% of the year's visitors, so a visit this month means sharing the park with the peak-season crowd.

You'll have about 14.9 hours of daylight in August to explore — between the 6.5-hour midwinter low and the 17.5-hour summer high.

Park-wide, 1994 drew 1,193 recreation visits, down 25.1% from 1,593 in 1993.

Across the past decade overall visitation has risen about 60.8%, so a August visit is likely to feel busier than it did a few years ago.
