Weather Briefing

VFR

Ljubljana Jože Pučnik Airport is currently reporting visual flight rules (VFR) conditions with scattered clouds at 12,000 feet and 10 miles or greater visibility.

Wind Analysis

Winds are calm, presenting no crosswind concerns for any runway.

Visibility & Ceiling

Visibility is unrestricted. No ceiling exists. Cloud layers reported: few at 4,500 ft, scattered at 12,000 ft.

Temperature & Moisture

Temperature is 18°C (64°F) with a dewpoint of 16°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 24 hours. Conditions are expected to fluctuate between VFR and MVFR. VFR pilots should be prepared for deteriorating conditions. Expected weather includes: Showers Rain. There is a 40% probability of MVFR conditions between 18:00Z and 22:00Z. Temporary MVFR conditions are forecast with Showers Rain between 22:00Z and 18:00Z. There is a 40% probability of VFR conditions between 23:00Z and 10:00Z.

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. 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 Ljubljana Jože Pučnik Airport

Overview

Ljubljana Jože Pučnik Airport serves as Slovenia's primary international airport, located in Zgornji Brnik at an elevation of 1,273 feet MSL. Positioned at coordinates 46.223701, 14.457600, the airport is a large facility strategically situated in the central region of Slovenia.

Flying Conditions

The airport's elevation at 1,273 feet above mean sea level suggests potential for variable weather conditions influenced by its inland mountain terrain. Pilots should anticipate potential wind variations and temperature changes that can impact aircraft performance, particularly during seasonal transitions.

Notable Features

The airport features a single runway (12/30) with a substantial length of 10,827 feet, capable of accommodating large commercial aircraft. Its positioning in the Slovenian landscape means pilots should be prepared for potential terrain-related wind shear and localized atmospheric conditions typical of mountainous regions.

Approach Considerations

Runway 12/30's extended length provides flexibility for various aircraft types and approach scenarios. Pilots should carefully assess current wind conditions and utilize the full runway length, taking into account the airport's elevation and potential terrain-induced wind patterns during approach and landing.
