Visa & Entry

Portugal is part of the US Visa Waiver Program. Portuguese passport holders enter the United States for up to 90 days without a visa, but must obtain an approved ESTA (Electronic System for Travel Authorization) before boarding. The ESTA costs USD 21, is valid for 2 years or until the passport expires, and covers multiple entries. Apply at the official CBP site (esta.cbp.dhs.gov) at least 72 hours before departure.

The 90-day stay cannot be extended, and you cannot change immigration status while in the US on the Visa Waiver Program.

Getting from SFO

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.

San Francisco Climate

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.
