Weather Briefing

VFR

John Wayne Orange County International Airport is currently reporting visual flight rules (VFR) conditions with clear skies and 10 SM visibility.

Wind Analysis

Winds are calm, presenting no crosswind concerns for any runway.

Visibility & Ceiling

Visibility is 10 SM. Skies are clear with unlimited ceiling.

Temperature & Moisture

Temperature is 18°C (64°F) with a dewpoint of 16°C. The temperature-dewpoint spread is very narrow, indicating saturated or near-saturated air. Fog formation or low cloud development is likely.

Forecast Outlook

The TAF forecast covers the next 24 hours. Conditions are expected to fluctuate between VFR and MVFR. VFR pilots should be prepared for deteriorating conditions.

Pilot Recommendations

Conditions are favorable for visual flight. The narrow temperature-dewpoint spread creates risk of fog formation, particularly during evening and early morning hours. The forecast indicates conditions may deteriorate. Ensure you have fuel reserves and a viable alternate airport.

This briefing is generated from real-time METAR and TAF data. Always verify with official sources before flight.

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.
