How Crowded Is Franklin Delano Roosevelt Memorial in September?

On our Best Time to Visit score September rates 66/100 ("Good") — the single best-rated month at Franklin Delano Roosevelt Memorial, balancing crowds against weather and daylight.

Typical September weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 81°F and an overnight low around 64°F, with about 3.9" of precipitation.

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

Because June, July and August together draw about 28% 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 12.2 hours of daylight in September to explore — between the 9.3-hour midwinter low and the 14.7-hour summer high.
