São Paulo to San Francisco (GRU–SFO) — Airlines, Schedules & Connections

Brazilian passport holders need a B1/B2 visa to enter the United States. Brazil is not part of the Visa Waiver Program, so ESTA is not available. The B1/B2 visa is typically issued with 10-year validity and allows stays of up to 180 days per visit. Interviews at a U.S. consulate in Brazil are required as part of the application.

CPTM Line 13-Jade commuter train runs from Luz station (central São Paulo) to the airport terminal in 33 minutes (R$4.40 integrated fare with metro). Trains run every 30 minutes from around 5am to midnight. This route is significantly cheaper than driving, as the Dutra highway (BR-116) suffers chronic congestion.Taxis from Paulista Avenue or Consolação cost R$90–150 and take 45–90 minutes depending on traffic. Ride-hails (99 or Uber) are widely used and typically R$70–120. Executive bus services (Guarucoop, Lira) run from Tietê terminal and Paulista (R$52–62). Traffic on the Dutra highway peaks heavily in afternoon and evening hours.

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.
