Getting to SFO

BART (Bay Area Rapid Transit) runs from downtown San Francisco (Embarcadero, Powell St.) to the SFO station and then a free AirTrain shuttle to all terminals (30–40 min from Embarcadero, $10.45). BART also connects Oakland and Berkeley; useful for East Bay travelers. Trains run from ~4am to midnight.Taxis from downtown San Francisco cost $40–60. Ride-hails (Uber, Lyft) pick up in the designated area in the garage and are often $30–50 depending on surge pricing. SamTrans buses serve Peninsula cities. Highway 101 and I-280 are heavily congested during commute hours; BART is faster than driving at those times.

Getting from BOS

Silver Line SL1 (free from Logan) runs to South Station in 15–20 minutes, connecting to the Red Line subway and Amtrak services. The Massport Shuttle connects all Logan terminals and the remote parking areas; it's also the transfer between terminals. Water taxi to Long Wharf (downtown) is $12 and runs seasonally; check weather and schedule.Taxis to downtown Boston cost $30–45 (tunnel toll included in meter). Ride-hails pick up at designated zones; follow the Logan app directions to avoid the main curb chaos. MBTA Blue Line (Airport station, free shuttle from terminals) reaches downtown in 10 minutes but requires a separate transfer. Amtrak Acela to New York departs from South Station (2.5h, from $49).

Boston Climate

Humid continental climate with significant maritime influence. Winters (December–March) bring regular Nor'easters. These coastal storms that dump heavy snow and produce high winds, frequently closing Logan for hours and causing mass cancellations. Ice storms hit several times each winter. BOS is one of the most weather-disrupted major US airports in winter.

Summers are warm (22–29°C) with humidity and afternoon thunderstorms causing July–August delays. Hurricane remnants reach New England in September–October. Spring and fall are mild (8–18°C) but unpredictable. Logan's harbor location means it runs windier than inland readings suggest. Factor this into small aircraft routing.
