How Crowded Is Marsh - Billings - Rockefeller National Historical Park in May?

On our Best Time to Visit score May rates 68/100 ("Good") — the single best-rated month at Marsh - Billings - Rockefeller, balancing crowds against weather and daylight.

Typical May weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 68°F and an overnight low around 43°F, with about 3.6" of precipitation.

That average of about 55°F is a comfortable range for hiking and being outdoors all day.

Because June, July and August together draw about 41% 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 14.5 hours of daylight in May to explore — between the 8.8-hour midwinter low and the 15.2-hour summer high.
