Weather Briefing

VFR

Gimpo International Airport is currently reporting visual flight rules (VFR) conditions with broken clouds at 20,000 feet and 10 miles or greater visibility.

Wind Analysis

Winds are from the north-northeast (20°) at 9 knots. Runway 32 is favored with a 5-knot headwind and 8-knot crosswind component.

Visibility & Ceiling

Visibility is unrestricted. The ceiling is 20000 feet AGL (broken), well above standard VFR minimums.

Temperature & Moisture

Temperature is 32°C (90°F) with a dewpoint of 21°C, indicating relatively dry conditions. High temperatures at this elevation may result in significant density altitude effects. Pilots should calculate density altitude and adjust performance expectations accordingly.

Forecast Outlook

The TAF forecast covers the next 30 hours. Conditions are expected to fluctuate between VFR and MVFR. VFR pilots should be prepared for deteriorating conditions. Expected weather includes: Light Showers Rain. Temporary MVFR conditions are forecast with Light Showers Rain between 06:00Z and 08:00Z.

Pilot Recommendations

Conditions are favorable for visual flight. 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 Gimpo International Airport

Overview

Gimpo International Airport serves as a major commercial airport located in Seoul, South Korea. Situated at an elevation of 59 feet mean sea level, the airport plays a critical role in the metropolitan transportation infrastructure for the Seoul region. The airport supports large-scale passenger and cargo operations with its two substantial asphalt runways.

Flying Conditions

As an airport in a temperate climate zone, Gimpo experiences variable seasonal weather conditions that can impact flight operations. The airport's lower elevation and proximity to coastal regions suggests potential for marine layer formations and variable wind patterns. Pilots should anticipate potential wind shifts between the two parallel runways during approach and departure.

Notable Features

The airport features two parallel runways with significant length: Runway 14L/32R at 11,811 feet and Runway 14R/32L at 10,499 feet. Both runways are constructed of asphalt, providing substantial landing and takeoff capabilities for a wide range of aircraft types. The parallel runway configuration allows for increased operational flexibility and potential simultaneous approach/departure procedures.

Approach Considerations

Runway orientation at 14/32 indicates a northwest-southeast alignment, which will influence approach and departure strategies based on prevailing wind conditions. The substantial runway lengths provide generous operating margins for most commercial and cargo aircraft. Pilots should review current wind data to determine optimal runway selection during arrival and departure planning.

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.
