Weather Briefing

MVFR

Bern Airport is currently reporting marginal VFR (MVFR) conditions with broken clouds at 2,100 feet and 6 km visibility.

Wind Analysis

Winds are from the west (280°) at 5 knots. Runway 32 is favored with a 4-knot headwind and 3-knot crosswind component.

Visibility & Ceiling

Visibility is 6 km, below VFR minimums in some airspace classifications. Check local requirements before departing VFR. The ceiling is 2100 feet AGL (broken), placing conditions in the MVFR category.

Temperature & Moisture

Temperature is 5°C (41°F) with a dewpoint of 4°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: Rain, Showers Rain, Thunderstorm Rain. Temporary IFR conditions are forecast with Rain between 06:00Z and 10:00Z. Temporary MVFR conditions are forecast with Showers Rain between 10:00Z and 15:00Z. There is a 30% probability of MVFR conditions with Thunderstorm Rain between 12:00Z and 15:00Z.

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 Bern Airport

Overview

Bern Airport serves as a medium-sized airport located in Switzerland at an elevation of 1,671 feet MSL. Situated near the capital city, the airport supports regional aviation with three runways accommodating different aircraft types. Its strategic location provides critical transportation infrastructure for the Bern metropolitan area.

Flying Conditions

Weather conditions at Bern Airport demonstrate significant variability, with Visual Flight Rules (VFR) prevailing 60.6% of the time. Pilots can expect predominantly southeastern winds averaging 4.6 knots, with temperatures ranging from -17°C to 29°C. September, November, and January offer the most consistent VFR conditions, while fog occurs in 13.1% of observations.

Notable Features

The airport features three runways: one asphalt surface (14/32) and two grass surfaces (14L/32R and 14R/32L). All runways demonstrate 100% favorable wind alignment, with minimal average crosswind of 2.6 knots. The diverse runway configuration allows operational flexibility across different aircraft and weather conditions.

Approach Considerations

With consistent southeastern wind patterns, approaches to runways 14 are typically most favorable. The primary asphalt runway (14/32) provides the longest surface at 5,676 feet, offering substantial landing and takeoff capabilities. Pilots should anticipate potential visibility challenges, as observations indicate potential instrument meteorological conditions during certain periods.
