How Crowded Is Antietam National Battlefield in January?

January runs about 0.2× Antietam National Battlefield's average month, which makes it a very quiet month here — roughly 2% of the park's yearly visitors come in January.

In a typical January the park sees roughly 4,200 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

It is the quietest month of the year at Antietam; by contrast July, the busiest, runs about 2× 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 62/100 — 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 41°F and an overnight low around 21°F, with about 3.1" of precipitation.

That average of about 31°F is cold, with winter conditions likely on higher ground.

Because June, July and August together draw about 39% 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 9.5 hours of daylight in January to explore — between the 9.2-hour midwinter low and the 14.8-hour summer high.

Park-wide, 2024 drew 197,340 recreation visits, up 28.5% from 153,560 in 2023.

Across the past decade overall visitation has eased about 60.5%, so January may feel a touch quieter than it once did.
