Understanding and Managing Airport Delays Due to Fog

June 22, 2026 · The Clime Team

Fog is a significant weather phenomenon that can lead to substantial delays at airports, particularly during the early morning and late evening hours when visibility is typically at its lowest. Understanding the causes, impacts, and strategies to manage these delays can help travelers navigate their journeys more effectively.

What Causes Airport Delays Due to Fog?

Fog reduces visibility, making it challenging for pilots to navigate safely during takeoff, landing, and taxiing. This reduction in visibility can lead to several operational challenges:

Reduced Arrival Capacity: Airports may limit the number of flights arriving per hour to maintain safety standards.
Ground Delay Programs (GDPs): To manage the flow of air traffic, the Federal Aviation Administration (FAA) may implement GDPs, holding departing flights at their origin airports until it's safe to proceed.
Diversions and Cancellations: Flights may be rerouted to alternative airports with better visibility or canceled if conditions do not improve.

Which Airports Are Most Affected by Fog Delays?

Certain airports are more susceptible to fog-related delays due to their geographical locations and operational characteristics:

San Francisco International Airport (SFO): SFO frequently experiences morning fog, leading to reduced arrival capacity and subsequent delays. For instance, in December 2025, thick fog prompted the FAA to initiate a ground-delay program at SFO, causing nationwide knock-on delays. (visahq.com)
Newark Liberty International Airport (EWR): EWR has been identified as one of the airports with the highest delay rates, with a 31.2% delay rate in 2026. Factors contributing to these delays include air traffic control congestion, volume exceeding runway capacity, and weather conditions such as fog. (flightqueue.com)

How Do Fog Delays Impact Travelers?

Fog-induced delays can have several repercussions for travelers:

Extended Wait Times: Delays can lead to longer wait times at airports, affecting subsequent connections and travel plans.
Increased Stress: Uncertainty regarding flight statuses and potential cancellations can cause anxiety and inconvenience.
Financial Implications: Extended delays may result in additional costs for meals, accommodations, and transportation.

How Can Travelers Manage Fog-Related Delays?

To mitigate the impact of fog-induced delays, travelers can consider the following strategies:

Stay Informed: Regularly check flight statuses and weather forecasts for both departure and arrival airports.
Plan for Alternatives: Identify alternative airports or routes that may be less affected by fog.
Allow Extra Time: Schedule flights with ample layover time to accommodate potential delays.
Utilize Technology: Leverage flight tracking apps and services that provide real-time updates and alerts.
