Stockholm to San Francisco (ARN–SFO) — Airlines, Schedules & Connections

Sweden is part of the US Visa Waiver Program. Swedish passport holders need an approved ESTA (Electronic System for Travel Authorization) before boarding. The ESTA costs USD 21, is valid for 2 years, and allows stays up to 90 days per visit. Apply online at the official CBP ESTA site at least 72 hours before departure. Your passport must be machine-readable and valid for the duration of the stay.

The Arlanda Express train runs non-stop from Stockholm Central Station to ARN in 18 minutes (SEK 280–320 one-way, cheaper booked online). The Pendeltåg (commuter rail) stops at Arlanda South/North stations for SEK 145 total (including a SEK 120 airport supplement); the journey takes 40 minutes.Taxis from central Stockholm cost SEK 600–800 (45–60 min). Uber runs SEK 400–600. The E4 motorway connects the airport to the city; traffic can be heavy southbound during afternoon rush. Driving takes 35–50 minutes in normal conditions.

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.
