How Crowded Is Hawaiʻi Volcanoes National Park in April?

April runs about 0.9× Hawaiʻi Volcanoes National Park's average month, which makes it an average month here — roughly 7% of the park's yearly visitors come in April.

In a typical April the park sees about 110,000 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes April the 9th-busiest of the park's twelve months, sitting between the January peak (1.2×) and the September low (0.8×).

On our Best Time to Visit score April rates 77/100 ("Excellent"), versus the top-rated September at 79/100 — pleasant weather with noticeably thinner crowds (shoulder season).

Typical April weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 80°F and an overnight low around 67°F, with about 1.9" 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 25% of annual visitors, choosing April instead steps outside that summer crush — the single biggest lever on how crowded the park feels.

You'll have about 12.4 hours of daylight in April to explore — between the 10.8-hour midwinter low and the 13.2-hour summer high.

Park-wide, 2025 drew 1,877,854 recreation visits, up 31% from 1,433,593 in 2024.

Across the past decade overall visitation has risen about 11.4%, so a April visit is likely to feel busier than it did a few years ago.
