Travel Essentials
IAD: EDT · SFO: PDT
When it's 6:00 PM in Dulles, it's 3:00 PM in San Francisco.
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).
BART from SFO station (free AirTrain from any terminal to the station) to downtown San Francisco takes 30–40 minutes ($10.45 to Embarcadero). Traffic on 101 can make taxis and ride-hails much slower during peak hours; BART skips all of that. BART also reaches Oakland, Berkeley, and Millbrae for Caltrain connections.Ride-hails from SFO use a dedicated garage pickup area; follow signs. Taxis are metered; downtown SF costs $40–60. Caltrain to the Peninsula (Mountain View, Palo Alto, San Jose) requires taking BART to Millbrae station for the transfer. Rental cars are at a consolidated facility accessible by AirTrain.
Coastal fog dominates the climate pattern. The thick marine layer ("Karl the Fog") rolls into SFO from the Pacific regularly in summer (June–September), causing significant low-visibility delays even on days that appear sunny inland. Morning fog burns off by afternoon most days, but persistent IFR conditions can last all day. This is the primary flight disruption risk at SFO.
Temperatures are mild year-round (10–20°C) with little seasonal variation. Winters bring rain (December–March) and occasional atmospheric river events that cause brief but intense flooding on the 101. Summers are cool. Pack a light jacket year-round. Wind off the bay affects small aircraft approach paths.
