How Crowded Is Cumberland Island National Seashore in May?

May runs about 1.3× Cumberland Island National Seashore's average month, which makes it a busy month here — roughly 11% of the park's yearly visitors come in May.

In a typical May the park sees roughly 6,800 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes May the 3rd-busiest of the park's twelve months, sitting between the March peak (1.6×) and the January low (0.6×).

On our Best Time to Visit score May rates 55/100 ("Fair"), versus the top-rated October at 76/100 — pleasant weather with noticeably thinner crowds (shoulder season).

Typical May weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 82°F and an overnight low around 65°F, with about 3.7" of precipitation.

That average of about 74°F is a comfortable range for hiking and being outdoors all day.

Because June, July and August together draw about 26% 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 13.6 hours of daylight in May to explore — between the 10-hour midwinter low and the 14-hour summer high.

Park-wide, 2025 drew 60,299 recreation visits, down 6.8% from 64,706 in 2024.

Across the past decade overall visitation has risen about 18.4%, so a May visit is likely to feel busier than it did a few years ago.
