June 22, 2026 · The Clime Team

Fog is a significant weather phenomenon that can disrupt airport operations, leading to delays and cancellations. Understanding how fog affects air travel and implementing strategies to mitigate its impact can enhance your travel experience.

How Does Fog Affect Airport Operations?

Fog reduces visibility, making it challenging for pilots to navigate during takeoff, landing, and taxiing. This diminished visibility can lead to:

Reduced Flight Capacity: Airports may limit the number of flights to ensure safety, leading to delays.
Ground Delays: Aircraft may be held on the ground until conditions improve, causing cascading delays.
Diversions and Cancellations: Flights unable to land at their intended destination may be diverted or canceled.

What Are the Primary Causes of Airport Fog Delays?

Several factors contribute to fog-related delays at airports:

Temperature and Humidity: Cool temperatures combined with high humidity levels can lead to fog formation.
Geographical Features: Airports situated near bodies of water or in valleys are more susceptible to fog.
Time of Day: Fog is more prevalent during early morning and late evening hours when temperatures are lower.

How Can Travelers Minimize the Impact of Fog Delays?

To reduce the impact of fog-related delays on your travel plans, consider the following strategies:

Stay Informed: Regularly check the FAA's Flight Information for real-time updates on airport conditions.
Choose High-Performing Airports: Opt for airports with a history of fewer delays. For instance, in 2025, Salt Lake City International Airport had an on-time performance of 84.32%, the highest among major U.S. airports. (kiplinger.com)
Book Morning Flights: Morning flights are less likely to be affected by fog, as conditions tend to worsen later in the day.
Allow Extra Time for Connections: If connecting through an airport prone to fog, ensure you have ample time between flights to accommodate potential delays.
Monitor Local Weather: Keep an eye on weather forecasts for your departure and arrival cities to anticipate foggy conditions.
