May is our recommended month at Lake Clark: the lightest crowds of the park's good-weather months.
The daily average of about 49°F is cool, so layers and a shorter daylight window matter. These figures are 1991–2020 NOAA climate normals from the nearest station, about 36.5 miles from the park.
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.
