About John Wayne Orange County International Airport

Overview

John Wayne Orange County International Airport serves the greater Los Angeles metropolitan area, strategically located in Santa Ana, California. As a large airport situated at 56 feet mean sea level, it provides critical commercial and general aviation services for Orange County and surrounding regions. The airport features two paved runways capable of handling diverse aircraft operations.

Flying Conditions

Southern California's coastal climate presents generally stable flying conditions with mild temperature variations throughout the year. The airport's low elevation at 56 feet MSL provides consistent atmospheric pressure and predictable wind patterns. Pilots can expect relatively stable weather conditions with minimal extreme meteorological challenges.

Notable Features

The airport's geographic positioning near the Pacific coastline creates unique aeronautical considerations for pilots. Two asymmetrical runways (02L/20R at 5700ft and 02R/20L at 2887ft) offer flexible approach and departure options depending on current wind conditions. The surrounding terrain is predominantly flat, with coastal influences that can generate localized wind shifts.

Approach Considerations

Runway orientation suggests potential preference for approaches aligned with 02/20 headings based on the airport's geometric layout. The longer runway (02L/20R) provides more flexibility for larger aircraft and complex approach scenarios. Pilots should anticipate potential wind variations typical of coastal Southern California environments when planning arrivals and departures.

Data Sources & Accuracy: Airport information sourced from OurAirports.com, a collaborative database of worldwide airport data. Weather data from official aviation weather services including NOAA Aviation Weather Center and international METAR/TAF providers. Information is updated regularly but pilots should always verify current conditions and NOTAMs through official channels before flight operations.
