How Crowded Is Rio Grande Wild & Scenic River in August?

August runs about 0.2× Rio Grande Wild & Scenic River's average month, which makes it a very quiet month here — roughly 2% of the park's yearly visitors come in August.

In a typical August the park sees about 20 recreation visits, based on National Park Service monthly counts from 1985 to 2025.

It is the quietest month of the year at Rio Grande; by contrast March, the busiest, runs about 2.6× the average — so August is the easiest time to have the place largely to yourself.

On our Best Time to Visit score August rates 75/100 ("Excellent"), versus the top-rated September at 80/100 — 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 96°F and an overnight low around 72°F, with about 1" of precipitation.

That average of about 84°F is warm enough that midday heat is worth planning around.

August falls inside the park's busiest stretch: June, July and August together pull about 13% of the year's visitors, so a visit this month means sharing the park with the peak-season crowd.

You'll have about 13.1 hours of daylight in August to explore — between the 10.1-hour midwinter low and the 13.9-hour summer high.

Park-wide, 2013 drew 703 recreation visits, down 25.8% from 947 in 2009.

Across the past decade overall visitation has risen about 37.1%, so a August visit is likely to feel busier than it did a few years ago.
