Weather Briefing

VFR

Jeju International Airport is currently reporting visual flight rules (VFR) conditions with scattered clouds at 2,000 feet and 10 miles or greater visibility.

Wind Analysis

Winds are from the east (90°) at 13 knots. Runway 07/25 is favored with a 12-knot headwind and 4-knot crosswind component.

Visibility & Ceiling

Visibility is unrestricted. No ceiling exists. Cloud layers reported: scattered at 2,000 ft.

Temperature & Moisture

Temperature is 17°C (63°F) with a dewpoint of 15°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 30 hours. Conditions are expected to remain VFR throughout the forecast period. Expect variable wind speeds ranging from 5 to 18 knots. Temporary VFR conditions are forecast between 18:00Z and 21:00Z.

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.

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.
