How Crowded Is Missouri National Recreational River in August?

August runs about 1.4× Missouri National Recreational River's average month, which makes it a busy month here — roughly 12% of the park's yearly visitors come in August.

In a typical August the park sees about 16,000 recreation visits, based on National Park Service monthly counts from 2004 to 2025.

That makes August the 3rd-busiest of the park's twelve months, sitting between the September peak (1.8×) and the February low (0.4×).

On our Best Time to Visit score August rates 59/100 ("Fair"), versus the top-rated May at 62/100 — 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 83°F and an overnight low around 61°F, with about 3.1" of precipitation.

That average of about 72°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 13.8 hours of daylight in August to explore — between the 8.9-hour midwinter low and the 15.1-hour summer high.

Park-wide, 2025 drew 166,390 recreation visits, up 8.4% from 153,521 in 2024.

Across the past decade overall visitation has risen about 11.4%, so a August visit is likely to feel busier than it did a few years ago.
