How Crowded Is El Malpais National Monument in August?

August runs about 1.1× El Malpais National Monument's average month, which makes it an average month here — roughly 9% 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 1988 to 2025.

That makes August the 8th-busiest of the park's twelve months, sitting between the May peak (1.4×) and the January low (0.5×).

On our Best Time to Visit score August rates 69/100 ("Good") — the single best-rated month at El Malpais, balancing crowds against weather and daylight.

Typical August weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 86°F and an overnight low around 52°F.

That average of about 69°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 30% 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 9.7-hour midwinter low and the 14.3-hour summer high.

Park-wide, 2025 drew 151,998 recreation visits, down 7.1% from 163,679 in 2024.

Across the past decade overall visitation has risen about 7.2%, so a August visit is likely to feel busier than it did a few years ago.
