Weather Briefing

VFR

Ulsan Airport is currently reporting visual flight rules (VFR) conditions with broken clouds at 4,000 feet and 10 miles or greater visibility. Note: This observation is 1.1 hours old and conditions may have changed.

Wind Analysis

Winds are from the south-southwest (200°) at 10 knots. Runway 18/36 is favored with a 9-knot headwind and 3-knot crosswind component.

Visibility & Ceiling

Visibility is unrestricted. The ceiling is 4000 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.

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 Ulsan Airport

Overview

Ulsan Airport serves the southeastern metropolitan region of South Korea, located in the industrial city of Ulsan. Positioned at 45 feet above mean sea level with coordinates 35.593498, 129.352005, the airport supports regional commercial and potential military aviation operations. As a medium-sized airport, it provides critical transportation infrastructure for the Ulsan metropolitan area.

Flying Conditions

The airport's coastal location near the Korean peninsula's southeastern shore suggests potential maritime weather influences and variable wind conditions. With a single runway (18/36) measuring 6,561 feet and constructed of asphalt, pilots should anticipate potential crosswind scenarios typical of coastal environments. Seasonal variations in temperature and precipitation can significantly impact approach and departure conditions.

Notable Features

Ulsan Airport's single runway orientation (18/36) indicates potential alignment with regional topographical or meteorological considerations. The relatively low elevation of 45 feet MSL suggests a relatively flat surrounding terrain, which may reduce certain terrain-related approach complexities. Its geographic position near an industrial region implies potential industrial traffic and associated airspace interactions.

Approach Considerations

Runway 18/36's substantial 6,561-foot length provides adequate operational flexibility for most medium-sized aircraft. Pilots should prepare for potential crosswind components given the coastal location, with careful attention to wind direction relative to the runway's single orientation. Standard instrument approach procedures will be critical for managing varying weather conditions in this maritime environment.
