How Crowded Is Kaloko-Honokōhau National Historical Park in May?

May runs about 0.9× Kaloko-Honokōhau National Historical Park's average month, which makes it an average month here — roughly 8% of the park's yearly visitors come in May.

In a typical May the park sees about 19,000 recreation visits, based on National Park Service monthly counts from 1988 to 2025.

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

On our Best Time to Visit score May rates 70/100 ("Good"), versus the top-rated September at 80/100 — 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 83°F and an overnight low around 71°F.

That average of about 77°F is warm enough that midday heat is worth planning around.

Because June, July and August together draw about 24% 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 12.9 hours of daylight in May to explore — near the year-round maximum.

Park-wide, 2025 drew 360,084 recreation visits, up 2.5% from 351,422 in 2024.

Across the past decade overall visitation has risen about 61.2%, so a May visit is likely to feel busier than it did a few years ago.
