How Crowded Is North Cascades National Park in August?

August runs about 3.6× North Cascades National Park's average month, which makes it a very busy month here — roughly 30% of the park's yearly visitors come in August.

In a typical August the park sees roughly 8,400 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 (3.6×) and the January low (0×).

On our Best Time to Visit score August rates 53/100 ("Fair"), versus the top-rated May at 75/100 — 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 79°F and an overnight low around 54°F, with about 1.5" of precipitation.

That average of about 66°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 70% of the year's visitors, so a visit this month means sharing the park with the peak-season crowd.

You'll have about 14.2 hours of daylight in August to explore — between the 8.1-hour midwinter low and the 15.9-hour summer high.

Park-wide, 2025 drew 46,925 recreation visits, up 184.7% from 16,485 in 2024.

Across the past decade overall visitation has risen about 38.2%, so a August visit is likely to feel busier than it did a few years ago.
