How Crowded Is Lake Clark National Park & Preserve in May?

May runs about 0.5× Lake Clark National Park & Preserve's average month, which makes it a very quiet month here — roughly 4% of the park's yearly visitors come in May.

In a typical May the park sees about 560 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 (3.3×) and the January low (0.1×).

On our Best Time to Visit score May rates 73/100 ("Good") — the single best-rated month at Lake Clark, balancing crowds against weather and daylight.

Typical May weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 59°F and an overnight low around 39°F, with about 0.4" of precipitation.

That average of about 49°F is cool, so layers and a shorter daylight window matter.

Because June, July and August together draw about 70% 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 16.9 hours of daylight in May to explore — between the 5.3-hour midwinter low and the 18.6-hour summer high.

Park-wide, 2017 drew 22,755 recreation visits, up 7.8% from 21,102 in 2016.

Across the past decade overall visitation has risen about 109.9%, so a May visit is likely to feel busier than it did a few years ago.
