WMATA Silver Line Metro now reaches Dulles directly; take Silver Line to Washington Dulles Airport station (about 65 min from Metro Center, ~$7). The connection opened in late 2022.Ride-shares from downtown DC run $35–60 and take 35–50 minutes via I-66 (longer during peak hours). Washington Flyer coach to Wiehle-Reston East Metro costs $6. The airport is 27 miles from downtown; taxis are expensive ($60–80).

Getting from DCA

The Metro station is inside Terminal B/C with covered walkway access; Terminal A requires a short outdoor walk or shuttle. Yellow and Blue line trains run to downtown DC in 15–25 minutes for $2.25–$3.85.

Taxis and Uber/Lyft operate from designated pick-up zones outside each terminal; fares to downtown run $15–30. DCA serves the National Mall area and is well-positioned for the U.S. Capitol, Pentagon, and downtown offices. International arrivals clear customs at DCA only for pre-cleared flights; most international traffic uses IAD (Dulles). Rental cars are in a consolidated facility accessible by shuttle.

Washington Climate

Humid subtropical climate. Summers (June–August) are hot and very humid at 29–34°C with frequent afternoon thunderstorms causing ground stops and airspace flow programs. The summer storm season is the primary operational disruption risk at DCA. Spring and autumn are transitional with variable conditions and occasional severe thunderstorm outbreaks.

Winters (December–February) bring cold temperatures (−2 to 7°C) with occasional snowstorms that disproportionately affect the DC area due to limited snow-removal infrastructure. Even moderate snowfall (5–10 cm) can shut regional airports for hours. Pack layers for winter; the region's storm response is notoriously inconsistent.
