The daily average of about 40°F is cool, so layers and a shorter daylight window matter. These figures are 1991–2020 NOAA climate normals from the nearest station, about 9.2 miles from the park.
Because June, July and August together draw about 63% of annual visitors, choosing April instead steps outside that summer crush — the single biggest lever on how crowded the park feels.
