How Crowded Is Yukon - Charley Rivers National Preserve in May?

May runs about 0.9× Yukon - Charley Rivers National Preserve's average month, which makes it an average month here — roughly 7% of the park's yearly visitors come in May.

In a typical May the park sees about 410 recreation visits, based on National Park Service monthly counts from 1982 to 2025.

That makes May the 5th-busiest of the park's twelve months, sitting between the August peak (3.4×) and the November low (0.1×).

On our Best Time to Visit score May rates 63/100 ("Good") — the single best-rated month at Yukon - Charley Rivers, balancing crowds against weather and daylight.

Typical May weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 61°F and an overnight low around 33°F, with about 1.1" of precipitation and roughly 1" of snow.

That average of about 47°F is cool, so layers and a shorter daylight window matter.

Because June, July and August together draw about 75% 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 18.3 hours of daylight in May to explore — between the 2.9-hour midwinter low and the 21.1-hour summer high.

Park-wide, 2018 drew 1,272 recreation visits, up 12.3% from 1,133 in 2015.

Across the past decade overall visitation has eased about 80.2%, so May may feel a touch quieter than it once did.
