The Federal Aviation Administration (FAA) activated a ground delay program at San Francisco International Airport (SFO) on August 13, 2026. Flights arriving at SFO experienced an average delay of 39 minutes, with some individual flights delayed by as much as one hour and 33 minutes. The program restricts arrivals to manage air traffic flow safely under current conditions.
Weather Impact and Operational Adjustments
Low cloud ceilings at San Francisco International Airport reduced visibility, limiting the number of aircraft that could arrive safely. Due to these conditions, some inbound flights remained at their departure airports awaiting clearance to proceed to SFO. Although the FAA ground delay
program primarily limits arriving flights, airlines also adjusted operations affecting departures from San Francisco, leading to possible schedule changes. Passengers traveling to or from SFO on August 13, 2026, should verify their flight status with airlines as delays continued to fluctuate with changing weather and traffic conditions.
