May is a favorable month to fly from Tempe-Phoenix East Terminal (TPET) to San Francisco International Airport (SFO). Expect warm, dry departure weather from the Tempe area and cool, potentially foggy mornings in the Bay Area that generally clear in the afternoon. For lower fares, target mid-week departures or early-May dates and avoid Memorial Day weekend if possible. Popular nearby destinations accessible from SFO include San Jose, Palo Alto (Silicon Valley), Oakland, Napa Valley, and Sonoma — plan ground transport accordingly. Book refundable or changeable tickets if your trip coincides with major tech conferences or university commencements in late May.
Arriving at San Francisco International Airport (SFO) in May is usually smooth—mornings can be cool and foggy but typically clear by midday, making afternoon and evening transfers reliable. Plan public transit connections to San Jose, Palo Alto, Oakland, or Napa; BART and Caltrain are effective for travelers heading to downtown San Francisco or Silicon Valley. Expect slightly higher demand around late-May holidays and university commencement dates; book airport shuttles and rental cars ahead of time. If you need to get to Napa Valley for wine-tasting, reserve a ride or transfer with ample lead time as weekend demand rises in May.
