Weather Briefing

MVFR

Gimpo International Airport is currently reporting marginal VFR (MVFR) conditions with clear skies and 6 km visibility.

Wind Analysis

Winds are from the south (170°) at 3 knots.

Visibility & Ceiling

Visibility is 6 km, below VFR minimums in some airspace classifications. Check local requirements before departing VFR. Skies are clear with unlimited ceiling.

Temperature & Moisture

Temperature is 20°C (68°F) with a dewpoint of 16°C. The narrow temperature-dewpoint spread suggests high humidity and potential for visibility restrictions, especially during cooling periods.

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.

Pilot Recommendations

VFR pilots should exercise caution. Consider filing IFR if instrument rated, or postponing the flight if conditions are expected to deteriorate further.

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.
