The daily average of about 55°F is a comfortable range for hiking and being outdoors all day. These figures are 1991–2020 NOAA climate normals from the nearest station, about 16.5 miles from the park.
Because June, July and August together draw about 47% 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 14.4 hours of daylight in May to explore — between the 9-hour midwinter low and the 15-hour summer high.
Park-wide, 2025 drew 3,682,771 recreation visits, down 3.7% from 3,823,242 in 2024.
Across the past decade overall visitation has eased about 7.8%, so May may feel a touch quieter than it once did.
