Weather Briefing

VFR

Shirak International Airport is currently reporting visual flight rules (VFR) conditions with clear skies and 10 miles or greater visibility.

Wind Analysis

Winds are from the north-northeast (20°) at 6 knots. Runway 02/20 is favored with a 6-knot headwind and 0-knot crosswind component.

Visibility & Ceiling

Visibility is unrestricted. Skies are clear with unlimited ceiling.

Temperature & Moisture

Temperature is 1°C (34°F) with a dewpoint of -1°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: Light Thunderstorm Rain. Temporary MVFR conditions are forecast with Light Thunderstorm Rain between 07:00Z and 18:00Z.

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 Shirak International Airport

Overview

Shirak International Airport serves Gyumri, Armenia, positioned at a significant elevation of 5000 ft MSL. The medium-sized airport provides critical aviation infrastructure in the region, with a substantial runway 02/20 measuring 10,564 feet in asphalted surface. Its geographical coordinates at 40.750401, 43.859299 place it in a strategically important mountainous terrain.

Flying Conditions

Weather patterns at Shirak demonstrate substantial variability, with Visual Flight Rules (VFR) conditions predominating at 71.3% of observations. Winter temperatures can plummet to -30°C, while summer peaks reach 26°C, creating diverse operational challenges. Winds predominantly originate from the northeast at 45 degrees, averaging 3.9 knots with occasional gusts up to 23 knots, and experiencing calm conditions 4.3% of the time.

Notable Features

The airport's high elevation at 5000 ft MSL significantly impacts aircraft performance and requires careful planning for takeoff and landing calculations. Terrain surrounding Gyumri introduces potential wind shear and turbulence considerations. Low Instrument Flight Rules (IFR) conditions occur in 3.2% of observations, indicating generally stable atmospheric conditions.

Approach Considerations

Runway 02/20 offers highly favorable wind alignment, with 100% wind compatibility and minimal average crosswind at 2.3 knots. September, October, and January represent the most consistent Visual Flight Rules months, providing predictable flying conditions. Pilots should anticipate potential temperature-related performance constraints due to the airport's significant elevation.
