Weather Briefing

VFR

M. R. Štefánik Airport is currently reporting visual flight rules (VFR) conditions with few clouds at 4,500 feet and 10 miles or greater visibility.

Wind Analysis

Winds are from the north (350°) at 4 knots.

Visibility & Ceiling

Visibility is unrestricted. No ceiling exists. Cloud layers reported: few at 4,500 ft (TCU). Caution: towering cumulus clouds reported at 4,500 ft AGL, indicating convective activity in the area.

Temperature & Moisture

Temperature is 12°C (54°F) with a dewpoint of 11°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 23 hours. The forecast shows a transition between VFR and IFR conditions. Pilots should monitor the forecast closely and have an alternate airport plan. Expected weather includes: Showers Rain, Thunderstorm Rain, Light Thunderstorm Rain. Temporary IFR conditions are forecast with Showers Rain between 19:00Z and 09:00Z. There is a 40% probability of IFR conditions with Thunderstorm Rain between 19:00Z and 01:00Z. There is a 40% probability of MVFR conditions with Light Thunderstorm Rain between 01:00Z and 06:00Z.

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 M. R. Štefánik Airport

Overview

M. R. Štefánik Airport serves as the primary international airport for Bratislava, Slovakia, located at coordinates 48.170200, 17.212700. Situated at an elevation of 436 feet MSL, this large airport provides critical aviation infrastructure for the region's commercial and potentially military operations.

Flying Conditions

As a facility at moderate elevation with two substantial concrete runways, the airport offers robust operational capabilities across different weather conditions. The airport's two runways - 04/22 at 9,515 feet and 13/31 at 10,466 feet - provide significant flexibility for aircraft handling various wind and approach scenarios throughout the year.

Notable Features

The airport's substantial runway lengths indicate capability for handling large commercial aircraft and potentially serving as a diversion airport for regional traffic. Its geographic location in western Slovakia suggests potential interactions with complex Central European airspace structures and potential terrain variations in surrounding approach corridors.

Approach Considerations

With two perpendicular runways of significant length, pilots have multiple approach options depending on prevailing wind conditions. The 10,466-foot runway 13/31 offers particularly generous landing and takeoff parameters, providing substantial operational margins for most commercial aircraft types.
