Understanding Fog-Induced Airport Delays: A Beginner's Guide

Fog is a common weather phenomenon that can significantly impact airport operations, leading to flight delays and cancellations. Understanding how fog affects air travel and how to stay informed can help travelers navigate these disruptions more effectively.

What Causes Fog-Related Flight Delays?

Fog reduces visibility, making it challenging for pilots to navigate safely during takeoff, landing, and taxiing. Airports have specific visibility thresholds; when these are not met, flights may be delayed or rerouted to ensure safety. For instance, San Francisco International Airport (SFO) often experiences morning fog, leading to reduced arrival capacity and subsequent delays. (sfbayweather.com)

How Does Fog Affect Different Airports?

The impact of fog varies by location:

  • San Francisco International Airport (SFO): Morning fog is common, leading to significant delays, especially for flights arriving between 7-11 a.m. (sfbayweather.com)

  • San Diego International Airport: Dense fog can cause numerous delays and cancellations, as seen in January 2025 when over 60 flights were affected. (kpbs.org)

  • LaGuardia Airport (LGA): While not as prone to fog, construction and other factors can lead to delays. For example, a Traffic Management Program was in effect due to runway and taxiway construction, causing average delays of 29 minutes for arriving flights. (fly.faa.gov)

How Can Travelers Stay Informed About Fog-Related Delays?

Staying updated on flight statuses is crucial during foggy conditions. The Federal Aviation Administration (FAA) provides real-time flight delay information, including weather-related delays. (faa.gov)
