Weather Briefing

MVFR

Jeju International Airport is currently reporting marginal VFR (MVFR) conditions with broken clouds at 2,000 feet and 10 miles or greater visibility.

Wind Analysis

Winds are from the north-northeast (30°) at 4 knots.

Visibility & Ceiling

Visibility is unrestricted. The ceiling is 2000 feet AGL (broken), placing conditions in the MVFR category.

Temperature & Moisture

Temperature is 25°C (77°F) with a dewpoint of 22°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. IFR conditions are expected to persist or develop. An instrument rating and IFR flight plan are recommended. Expected weather includes: Light Rain, Rain. Temporary IFR conditions are forecast between 00:00Z and 02:00Z. Temporary IFR conditions are forecast between 03:00Z and 08:00Z. Temporary IFR conditions are forecast between 15:00Z and 21:00Z.

Pilot Recommendations

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

Overview

Jeju International Airport serves as the primary aviation gateway to Jeju Island, located off the southern coast of South Korea. Situated at an elevation of 118 ft MSL, the airport handles significant passenger traffic as the main air transportation hub for this popular tourist destination. Its strategic location and substantial infrastructure support both domestic and international commercial aviation operations.

Flying Conditions

Jeju's maritime island location generates complex and dynamic weather patterns that pilots must carefully anticipate. The airport's dual runway configuration (07/25 at 10,433 ft and 13/31 at 6,268 ft) provides operational flexibility during varying wind conditions. Seasonal wind shifts and potential marine layer developments can significantly impact approach and departure procedures.

Notable Features

The airport is characterized by its substantial runway lengths, with the primary 07/25 runway offering over 10,000 feet of asphalt surface. Its proximity to coastal terrain means pilots should be prepared for potential wind shear and turbulence, particularly during seasonal transition periods. The airport's geographical position at 33.512058, 126.492548 places it in a unique meteorological environment influenced by both maritime and continental air masses.

Approach Considerations

Runway selection will typically depend on prevailing wind directions, with the 07/25 and 13/31 runways providing crosswind options. The extended primary runway (07/25) offers significant landing and takeoff performance advantages for larger aircraft. Pilots should maintain heightened situational awareness regarding potential rapid weather changes typical of island airport environments.
