Typical December weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 27°F and an overnight low around 12°F, with about 1.2" of precipitation and roughly 15" of snow.

That average of about 20°F is cold, with winter conditions likely on higher ground.

Because June, July and August together draw about 66% of annual visitors, choosing December instead steps outside that summer crush — the single biggest lever on how crowded the park feels.

You'll have about 8.5 hours of daylight in December to explore — near the year-round minimum.

Park-wide, 2025 drew 852,296 recreation visits, down 5.4% from 900,828 in 2024.

Across the past decade overall visitation has risen about 20.9%, so a December visit is likely to feel busier than it did a few years ago.
