The Federal Aviation Administration activated a ground delay program at San Francisco International Airport (SFO) on August 13, 2026, due to low cloud ceilings reducing visibility and limiting the number of aircraft air traffic controllers can safely allow to arrive.
Flight Arrival Delays at SFO
Flights arriving at SFO experienced an average delay of 39 minutes, with some individual delays reaching approximately 1 hour and 33 minutes as the FAA managed reduced visibility conditions.
Operational Impact on Departures and Arrivals
Some flights remained grounded at their departure airports awaiting clearance to proceed to San Francisco. While the ground delay program primarily controls arrivals, departing flights from SFO may also face schedule
changes as airlines adjust their operations in response to delays.
Traveler Advisory
Passengers flying to or from San Francisco International Airport on August 13, 2026, are advised to check their flight status directly with airlines due to continuing delays amid fluctuating visibility and air traffic conditions, according to Cedar News.
