How Crowded Is Wind Cave National Park in May?

May runs about 1.1× Wind Cave National Park's average month, which makes it an average month here — roughly 10% of the park's yearly visitors come in May.

In a typical May the park sees about 57,000 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes May the 5th-busiest of the park's twelve months, sitting between the July peak (2.5×) and the January low (0.2×).

On our Best Time to Visit score May rates 60/100 ("Good") — the single best-rated month at Wind Cave, balancing crowds against weather and daylight.

Typical May weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 66°F and an overnight low around 41°F, with about 3.7" of precipitation.

That average of about 54°F is a comfortable range for hiking and being outdoors all day.

Because June, July and August together draw about 55% of annual visitors, choosing May instead steps outside that summer crush — the single biggest lever on how crowded the park feels.

You'll have about 14.5 hours of daylight in May to explore — between the 8.8-hour midwinter low and the 15.2-hour summer high.

Park-wide, 2025 drew 606,258 recreation visits, up 23.9% from 489,399 in 2024.
