How Crowded Is Cabrillo National Monument in August?

August runs about 1.1× Cabrillo National Monument's average month, which makes it an average month here — roughly 9% of the park's yearly visitors come in August.

In a typical August the park sees about 80,000 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes August the 2nd-busiest of the park's twelve months, sitting between the July peak (1.3×) and the September low (0.9×).

On our Best Time to Visit score August rates 69/100 ("Good"), versus the top-rated September at 89/100 — 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 77°F and an overnight low around 67°F.

That average of about 72°F is a comfortable range for hiking and being outdoors all day.

August falls inside the park's busiest stretch: June, July and August together pull about 29% of the year's visitors, so a visit this month means sharing the park with the peak-season crowd.

You'll have about 13.2 hours of daylight in August to explore — between the 9.9-hour midwinter low and the 14.1-hour summer high.

Park-wide, 2024 drew 845,912 recreation visits, up 4.4% from 810,147 in 2023.

Across the past decade overall visitation has eased about 17.2%, so August may feel a touch quieter than it once did.
