Weather Briefing

MVFR

Semey Airport is currently reporting marginal VFR (MVFR) conditions with broken clouds at 3,000 feet and 6 km visibility.

Wind Analysis

Winds are from the west-southwest (240°) at 17 knots. Runway 26 is favored with a 16-knot headwind and 6-knot crosswind component. Student pilots and low-time aviators should exercise caution.

Visibility & Ceiling

Visibility is 6 km, below VFR minimums in some airspace classifications. Check local requirements before departing VFR. The ceiling is 3000 feet AGL (broken), well above standard VFR minimums. Caution: cumulonimbus (thunderstorm) clouds reported at 3,000 ft AGL, indicating convective activity in the area.

Temperature & Moisture

Temperature is 19°C (66°F) with a dewpoint of 17°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 9 hours. IFR conditions are expected to persist or develop. An instrument rating and IFR flight plan are recommended. Expected weather includes: Light Thunderstorm Rain, Squalls. Temporary IFR conditions are forecast with Light Thunderstorm Rain, Squalls between 06:00Z and 12:00Z.

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 Semey Airport

Overview

Semey Airport serves the eastern Kazakhstan city of Semey, functioning as a medium-sized regional airport. Located at an elevation of 761 feet MSL, the airport provides critical transportation infrastructure in this remote region of Kazakhstan. Its two concrete runways offer substantial operational capabilities for various aircraft types.

Flying Conditions

Pilots can expect predominantly VFR conditions at this airport, with 74.3% of observations indicating good visual flying conditions. The temperature range is extreme, spanning from -37°C to 28°C, suggesting significant seasonal weather variations. September through November represent the most consistent VFR months, offering the most stable flying environment.

Notable Features

The airport features two concrete runways with significant length variations: a shorter 3,270 ft runway (02/20) and a longer 10,159 ft runway (08/26). Its geographical position at coordinates 50.351295, 80.234398 places it in a region with potential for rapid weather changes. The low frequency of reduced visibility conditions (IFR and LIFR totaling only 11.2%) indicates generally reliable visual meteorological conditions.

Approach Considerations

With minimal wind data provided, pilots should consult current local meteorological reports for specific wind conditions. The substantial runway length, particularly the 10,159 ft runway, provides flexibility for different aircraft types and approach scenarios. Visibility averages 10 statute miles, with very rare instances of reduced visibility, suggesting generally favorable approach conditions.
