The Federal Aviation Administration activated a ground delay program at San Francisco International Airport (SFO) on August 14, 2026, restricting arrivals to manage air traffic flow amid low cloud ceilings and adverse weather conditions.
Flights arriving at SFO are facing delays averaging 39 minutes, with some individual delays reaching as long as one hour and 33 minutes. The low cloud ceilings reduce visibility and limit the number of aircraft air traffic controllers can safely allow to land.
Air traffic controllers are limiting arrivals at SFO due to the reduced visibility from low cloud ceilings. Some flights may remain at their
departure airports until receiving clearance to continue toward San Francisco.
Departing flights from SFO are also experiencing schedule changes as airlines adjust operations in response to the ground delay program.
Operational Impact and Traveler Guidance
Travelers at San Francisco International Airport should confirm their flight status directly with their airline before departing. The FAA ground delay program is used to manage air traffic flow safely under the adverse weather conditions causing the disruption.
