About Grenoble Alpes Isère Airport

Overview

Grenoble Alpes Isère Airport serves the Grenoble metropolitan area in southeastern France, situated at 1302 ft MSL. The airport supports regional and seasonal aviation operations, particularly important for alpine tourism and transportation. Its strategic location near mountainous terrain makes it a significant gateway for the Isère region.

Flying Conditions

Pilots can expect predominantly VFR conditions 59.9% of the time, with MVFR and IFR conditions occurring 34.2% of observations. Temperature variations are substantial, ranging from -9°C to 29°C, with an average of 7.9°C. Wind patterns consistently favor an easterly direction (90°) at an average of 6.7 knots, with maximum gusts reaching 28 knots.

Notable Features

The airport features a single runway 09/27 with a substantial length of 10,007 feet, constructed with asphalt surface. Its mountain proximity influences local weather dynamics, contributing to the 10.2% fog occurrence rate. The terrain suggests potential for complex local wind and visibility conditions typical of alpine regions.

Approach Considerations

Runway 09/27 demonstrates extremely favorable wind alignment, with 100% wind compatibility. Average crosswind is minimal at 3.6 knots, providing generally stable approach conditions. Pilots should note September, January, and October offer the most consistent VFR flying conditions based on historical meteorological data.
