How Crowded Is Piscataway Park in May?

May runs about 1.2× Piscataway Park's average month, which makes it a busy month here — roughly 10% of the park's yearly visitors come in May.

In a typical May the park sees about 23,000 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 June peak (1.3×) and the January low (0.5×).

On our Best Time to Visit score May rates 27/100 ("Poor"), versus the top-rated January at 78/100 — the best overall balance of crowds and daylight.

Because June, July and August together draw about 31% 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 14.1 hours of daylight in May to explore — between the 9.3-hour midwinter low and the 14.7-hour summer high.

Park-wide, 2025 drew 275,070 recreation visits, down 17.7% from 334,260 in 2024.

Across the past decade overall visitation has risen about 53.8%, so a May visit is likely to feel busier than it did a few years ago.
