How Crowded Is Katmai National Park & Preserve in August?

August runs about 3.2× Katmai National Park & Preserve's average month, which makes it a very busy month here — roughly 26% of the park's yearly visitors come in August.

In a typical August the park sees about 14,000 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes August the 2nd-busiest of the park's twelve months, sitting between the July peak (5.1×) and the January low (0×).

On our Best Time to Visit score August rates 50/100 ("Fair"), versus the top-rated May at 69/100 — 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 83% of the year's visitors, so a visit this month means sharing the park with the peak-season crowd.

You'll have about 15.2 hours of daylight in August to explore — between the 6-hour midwinter low and the 18-hour summer high.

Park-wide, 2023 drew 33,763 recreation visits, down 34.5% from 51,511 in 2020.

Across the past decade overall visitation has eased about 10.3%, so August may feel a touch quieter than it once did.
