How Crowded Is Tumacácori National Historical Park in July?

July runs about 0.4× Tumacácori National Historical Park's average month, which makes it a very quiet month here — roughly 3% of the park's yearly visitors come in July.

In a typical July the park sees roughly 1,200 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes July the 10th-busiest of the park's twelve months, sitting between the December peak (2.2×) and the August low (0.4×).

On our Best Time to Visit score July rates 76/100 ("Excellent"), versus the top-rated August at 78/100 — pleasant weather with noticeably thinner crowds (shoulder season).

Typical July weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 93°F and an overnight low around 67°F, with about 3.8" of precipitation.

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

July falls inside the park's busiest stretch: June, July and August together pull about 9% of the year's visitors, so a visit this month means sharing the park with the peak-season crowd.

You'll have about 13.9 hours of daylight in July to explore — near the year-round maximum.

Park-wide, 2024 drew 35,256 recreation visits, down 6.9% from 37,872 in 2023.

Across the past decade overall visitation has eased about 20.6%, so July may feel a touch quieter than it once did.
