How Crowded Is Dry Tortugas National Park in August?

August runs about 1× Dry Tortugas National Park's average month, which makes it an average month here — roughly 8% of the park's yearly visitors come in August.

In a typical August the park sees roughly 6,000 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes August the 7th-busiest of the park's twelve months, sitting between the June peak (1.2×) and the October low (0.7×).

On our Best Time to Visit score August rates 44/100 ("Poor"), versus the top-rated February at 65/100 — pleasant weather with noticeably thinner crowds (shoulder season).

Typical August weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 91°F and an overnight low around 79°F, with about 4.3" of precipitation.

That average of about 85°F is warm enough that midday heat is worth planning around.

August falls inside the park's busiest stretch: June, July and August together pull about 28% of the year's visitors, so a visit this month means sharing the park with the peak-season crowd.

You'll have about 12.9 hours of daylight in August to explore — between the 10.5-hour midwinter low and the 13.5-hour summer high.

Park-wide, 2025 drew 89,355 recreation visits, up 5.3% from 84,873 in 2024.

Across the past decade overall visitation has risen about 34.7%, so a August visit is likely to feel busier than it did a few years ago.
