Understanding the Most Delay-Prone Weather Conditions at Airports

Weather-related disruptions are the leading cause of flight delays in the United States, accounting for over 74% of significant delays. (faa.gov) Understanding these conditions is crucial for both travelers and aviation professionals.

What Are the Most Delay-Prone Weather Conditions?

Several weather phenomena are particularly disruptive to air travel:

  • Thunderstorms: These storms can lead to severe turbulence, lightning, hail, and low visibility, often resulting in flight rerouting or cancellations. (faa.gov)

  • Heavy Snow and Ice: Accumulation on runways and aircraft surfaces can delay departures and arrivals, as de-icing procedures are time-consuming and essential for safety. (unanswered.io)

  • Low Visibility (Fog): Reduced visibility can prevent pilots from safely taking off or landing, leading to delays or diversions. (afar.com)

  • Strong Winds: High winds, especially during takeoff and landing, can be hazardous, causing delays or cancellations. (afar.com)

Which Airports Are Most Affected?

Certain airports are more susceptible to weather-related delays due to their geographic locations and typical weather patterns:

  • Chicago O'Hare International Airport (ORD): Experiences the highest number of weather-related delays, averaging over 25,000 per year, primarily due to snow and thunderstorms. (weather.com)

  • Newark Liberty International Airport (EWR): Faces significant delays, with nearly 30,000 significant delays over 15 minutes in 2022, often due to weather conditions. (faa.gov)

  • LaGuardia Airport (LGA): Also experiences a high number of weather-related delays, with nearly 30,000 significant delays in 2022. (faa.gov)
