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

September runs about 0.8× Kaloko-Honokōhau National Historical Park's average month, which makes it a quiet month here — roughly 6% of the park's yearly visitors come in September.

In a typical September the park sees about 16,000 recreation visits, based on National Park Service monthly counts from 1988 to 2025.

It is the quietest month of the year at Kaloko-Honokōhau; by contrast March, the busiest, runs about 1.2× the average — so September is the easiest time to have the place largely to yourself.

On our Best Time to Visit score September rates 80/100 ("Excellent") — the single best-rated month at Kaloko-Honokōhau, balancing crowds against weather and daylight.

Typical September weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 86°F and an overnight low around 73°F.

That average of about 80°F is warm enough that midday heat is worth planning around.

Because June, July and August together draw about 24% of annual visitors, choosing September instead steps outside that summer crush — the single biggest lever on how crowded the park feels.

You'll have about 12.1 hours of daylight in September to explore — between the 10.8-hour midwinter low and the 13.2-hour summer high.

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 September visit is likely to feel busier than it did a few years ago.
