Milky Way & dark skies
From Pennsylvania Avenue, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 5.0 hours on a moonless night), and the core peaks around 22° above the southern horizon. Our light-pollution model puts the sky at about Bortle 9 (inner-city sky), so expect visible sky glow; drive away from towns for better results.

Weather overview: National Park Service.
Long-term NASA satellite data for this area show September as the clearest month (about 52% average cloud cover) and May as the cloudiest (61%). July is the warmest month and January the coldest, which matters for gear, snow access and how long batteries last at night.

Photography permits, drones & fees
Permits. Under federal law (54 U.S.C. 100905), still photography in National Park Service areas needs a permit only when it (1) takes place where members of the public are not allowed, (2) uses models, sets or props that are not part of the location's natural or cultural resources or administrative facilities, or (3) would cause the park to incur additional administrative costs to monitor the activity. Ordinary visitor and most landscape photography needs no permit. Commercial filming rules are separate and have changed in recent years — confirm current requirements with the park before a paid shoot.
Drones. Launching, landing or operating unmanned aircraft (drones) is prohibited in National Park Service units under a 2014 Superintendent's closure (36 CFR 1.5), except where a park has issued specific written approval. Flying from outside the boundary over park land can also violate park rules and disturb wildlife.
Getting there
Pennsylvania Avenue National Historic Site is part of National Mall and Memorial Parks. The avenue is among the world's more famous streets and is known the world over as the heart of the Nation's Capital, extending through the corridors of Federal power and influence. "America's Main Street" visually connects, yet separates, the White House from the U.S. Capitol and the U.S. Supreme Court buildings.
