About John C. Munro Hamilton International Airport

Overview

John C. Munro Hamilton International Airport serves as a critical medium-sized airport located in Hamilton, Ontario, Canada. Situated at 780 feet above mean sea level with coordinates 43.173599, -79.934998, the airport provides important regional aviation infrastructure with two substantial asphalt runways capable of handling diverse aircraft operations.

Flying Conditions

Weather conditions at CYHM demonstrate significant variability, with visual flight rules (VFR) predominating at 64.5% of observed periods. Pilots should anticipate prevailing southwest winds averaging 9.6 knots, with temperature ranges extending from -17°C to 28°C. Seasonal visibility averages 12.2 statute miles, though periods of reduced visibility occur, with fog present in 5.8% of observations and conditions dropping below 3 statute miles in 3.7% of reports.

Notable Features

The airport features two parallel runways: 06/24 measuring 6,010 feet and 12/30 extending 10,006 feet, both constructed of asphalt surface. Both runways demonstrate 100% favorable wind alignment, with Runway 12/30 experiencing a slightly higher average crosswind of 7.6 knots compared to Runway 06/24's 4-knot average crosswind. September, October, and November consistently provide the most favorable visual flying conditions.

Approach Considerations

Pilots should plan approaches considering the prevailing southwest winds at 225 degrees. With wind speeds typically around 9.6 knots and potential gusts up to 35 knots, careful wind assessment is crucial during arrival and departure. The longer Runway 12/30 offers additional operational flexibility, particularly during variable wind conditions.
