How Crowded Is Thomas Edison National Historical Park in January?

January runs about 0.6× Thomas Edison National Historical Park's average month, which makes it a quiet month here — roughly 5% of the park's yearly visitors come in January.

In a typical January the park sees roughly 2,300 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

It is the quietest month of the year at Thomas Edison; by contrast August, the busiest, runs about 1.6× the average — so January is the easiest time to have the place largely to yourself.

On our Best Time to Visit score January rates 43/100 ("Poor"), versus the top-rated September at 75/100 — pleasant weather with noticeably thinner crowds (shoulder season).

Typical January weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 38°F and an overnight low around 21°F, with about 3.6" of precipitation.

That average of about 30°F is cold, with winter conditions likely on higher ground.

Because June, July and August together draw about 37% of annual visitors, choosing January instead steps outside that summer crush — the single biggest lever on how crowded the park feels.

You'll have about 9.4 hours of daylight in January to explore — between the 9.1-hour midwinter low and the 14.9-hour summer high.

Park-wide, 2021 drew 14,807 recreation visits, down 64.9% from 42,224 in 2019.

Across the past decade overall visitation has eased about 15.6%, so January may feel a touch quieter than it once did.
