How Crowded Is Great Smoky Mountains National Park in August?

August runs about 1.2× Great Smoky Mountains National Park's average month, which makes it a busy month here — roughly 10% of the park's yearly visitors come in August.

In a typical August the park sees 1.3 million recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes August the 4th-busiest of the park's twelve months, sitting between the July peak (1.5×) and the January low (0.4×).

On our Best Time to Visit score August rates 53/100 ("Fair") — the single best-rated month at Great Smoky Mountains, balancing crowds against weather and daylight.

Typical August weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 72°F and an overnight low around 57°F, with about 5.1" of precipitation.

That average of about 64°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 35% of the year's visitors, so a visit this month means sharing the park with the peak-season crowd.

You'll have about 13.3 hours of daylight in August to explore — between the 9.6-hour midwinter low and the 14.4-hour summer high.

Park-wide, 2025 drew 11,527,939 recreation visits, down 5.4% from 12,191,834 in 2024.

Across the past decade overall visitation has risen about 9.2%, so a August visit is likely to feel busier than it did a few years ago.
