Weather Briefing
VFRGrenchen Airfield is currently reporting visual flight rules (VFR) conditions with clear skies and 10 miles or greater visibility.
Wind Analysis
Winds are calm, presenting no crosswind concerns for any runway.
Visibility & Ceiling
Visibility is unrestricted. Skies are clear with unlimited ceiling.
Temperature & Moisture
Temperature is 14°C (57°F) with a dewpoint of 14°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. Conditions are expected to fluctuate between VFR and MVFR. VFR pilots should be prepared for deteriorating conditions. Expected weather includes: Showers Rain, Thunderstorm Rain. Temporary MVFR conditions are forecast with Showers Rain between 15:00Z and 00:00Z. There is a 30% probability of MVFR conditions with Thunderstorm Rain between 15:00Z 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.

About Grenchen Airfield
Overview
Grenchen Airfield is a medium-sized airport located in Switzerland, positioned at an elevation of 1,411 feet MSL near the coordinates 47.181599, 7.417190. The airport features multiple runways, including paved and grass surfaces, serving regional aviation needs in the Grenchen area.
Flying Conditions
Weather conditions at Grenchen demonstrate significant variability, with Visual Flight Rules (VFR) prevailing 45.2% of the time. Meteorological data indicates a wide temperature range from -12°C to 27°C, with an average of 5.9°C. Pilots can expect predominantly southwestern winds averaging 5.8 knots, with September through November offering the most favorable VFR conditions.
Notable Features
The airport offers three primary runways: a 3,281-foot asphalted runway (06/24), and two grass runways at 1,640 feet (06L/24R) and 2,297 feet (06R/24L). Fog is present 16.5% of the time, which can impact visibility, though the average visibility remains strong at 10 statute miles. Wind conditions are generally consistent, with calm periods occurring 16.1% of the time.
Approach Considerations
All runways demonstrate 100% favorable wind alignment, with minimal average crosswind components ranging from 1.4 to 1.5 knots. The southwestern prevailing wind at 225 degrees provides predictable approach conditions, with maximum recorded wind speeds of 27 knots. Pilots should be prepared for potential reduced visibility during fog events, particularly during months with less favorable VFR conditions.
