Weather Briefing
VFRDuluth International Airport is currently reporting visual flight rules (VFR) conditions with clear skies and 10 SM visibility.
Wind Analysis
Winds are from the south (180°) at 9 knots. Runway 21 is favored with a 8-knot headwind and 5-knot crosswind component.
Visibility & Ceiling
Visibility is 10 SM. Skies are clear with unlimited ceiling.
Temperature & Moisture
Temperature is 11°C (52°F) with a dewpoint of 8°C. The narrow temperature-dewpoint spread suggests high humidity and potential for visibility restrictions, especially during cooling periods.
Forecast Outlook
The TAF forecast covers the next 24 hours. Conditions are expected to remain VFR throughout the forecast period.
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.
This briefing is generated from real-time METAR and TAF data. Always verify with official sources before flight.

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.
