About Austin Straubel International Airport

Overview

Austin Straubel International Airport serves Green Bay, Wisconsin as a medium-sized airport with substantial runway capacity. Located at coordinates 44.483459, -88.130805 and elevated at 695 ft MSL, the airport provides critical transportation infrastructure for northeastern Wisconsin. The airport features three runways with substantial lengths, enabling diverse aircraft operations.

Flying Conditions

Weather conditions at KGRB demonstrate significant variability, with visual flight rules (VFR) predominating at 65% of observations. Temperature ranges dramatically from -28°C to 31°C, requiring pilots to prepare for extreme thermal conditions. Prevailing westerly winds at an average of 8.4 knots with occasional gusts up to 26 knots characterize the airport's wind profile, with calm conditions occurring 14% of the time.

Notable Features

The airport's three runways offer comprehensive operational flexibility, with two concrete runways (06/24 at 7700ft and 18/36 at 8201ft) and one asphalt runway (12/30 at 3198ft). All runways demonstrate 100% favorable wind alignment, with modest average crosswind components between 5-5.7 knots. Visibility averages 8.7 statute miles, though pilots should anticipate reduced visibility scenarios where conditions drop below 3 miles in 5.4% of observations.

Approach Considerations

Optimal VFR flying conditions occur during autumn months (September, October, November), providing the most consistent meteorological environment. Fog appears in approximately 7% of observations, suggesting potential instrument approach requirements. Pilots should anticipate westerly wind influences and prepare for potential instrument meteorological conditions, particularly during shoulder seasons when MVFR conditions represent 21.9% of observations.
