Milky Way & dark skies
From Greenbelt, 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 & best time to visit
The Washington, D.C. area has a four-season Mid-Atlantic climate. Summertime is warm and humid, while winter can be cold and snowy. Spring: During these months of transition, the weather can alternate from warm, humid air coming from the south to cold, dry air coming from the northwest. Be prepared for changing conditions. Summer: The warmest months are June, July, and August, with average highs in the 80s (~31 ?) combined with high humidity. Fall: Expect a drop in temperature and humidity in September
Weather overview: National Park Service.
Long-term NASA satellite data for this area show September as the clearest month (about 50% average cloud cover) and January 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.
