Right now we don’t have enough information to tell when the weather will improve, and the current situation is already causing flights to be delayed and canceled.

Travelers should expect these delays and cancellations to continue.

Why Is This Happening?

Here are the current weather conditions at San Francisco International and an overview of what is required for “normal” operations:

Normal Current
Visibility Greater than 2 10.0
Wind Less than 11.8 MPH 20.0 MPH
Clouds Higher than 1,000 Few at 800
Scattered at 1,300
Broken at 1,500

The airport is currently experiencing delays due to low clouds and poor visibility. While airplanes can fly through clouds without an issue, landing usually requires the pilot to be able to see the runway. In situations such as these where pilots can’t see the ground or other airplanes air traffic control will keep flights further apart than normal. This keeps everyone safe, but decreases the number of flights that can take off and land which causes delays.

Cloud conditions are not expected to change significantly between now and 9:00 PM on 5/21.

Visibility is not expected to change significantly.

MEDIUM LOW LOW

Since this is a temporary situation it is expected that the delay will not continue for very long. As such while your flight may see a minor delay it is not likely to be canceled unless there are other issues for that specific flight.

Why Is This Happening?

Airports sometimes experience situations where more aircraft are trying to take off and land than the air traffic controllers can safely handle. During these periods the air traffic controllers can slow down the rate at which new aircraft are allowed into the area. This process is called “metering,” and will end when the local air traffic controllers can safely handle normal operations again. As such there is no way to definitely say when the delays will end.
