About Duluth International Airport

Overview

Duluth International Airport serves the northeastern Minnesota region, strategically located near Lake Superior. As a medium-sized airport at 1428 feet MSL, it provides critical aviation infrastructure for commercial, cargo, and general aviation operations in a climatically challenging environment.

Flying Conditions

Weather at Duluth is characterized by significant variability, with flight rules predominantly VFR (60.1%) but substantial periods of instrument conditions. Temperature ranges dramatically from -34°C to 29°C, creating complex meteorological challenges, with an average temperature near freezing at -0.4°C. Visibility averages 8.3 statute miles, though pilots should anticipate reduced visibility during 9% of observations and fog presence in 10.4% of reports.

Notable Features

The airport features two substantial runways: a 5,699-foot asphalt runway (03/21) and a longer 10,152-foot concrete runway (09/27). Prevailing winds from the northwest (315°) average 9.4 knots, with maximum gusts reaching 26 knots and calm conditions occurring 6.5% of the time. Both runways demonstrate 100% favorable wind alignment, providing flexible operational capabilities.

Approach Considerations

Seasonal considerations are critical, with October, November, and September offering the most consistent VFR conditions. Crosswind components are moderate, averaging 7.4 knots on runway 03/21 and 5.5 knots on runway 09/27. Pilots should prepare for potential rapid weather changes typical of a Great Lakes region airport proximate to significant water geography.
