Pilots can expect prevailing westerly winds averaging 9.4 knots, with temperature ranges from -24°C to 37°C. September, October, and January offer the most consistently favorable VFR conditions, while visibility typically remains excellent at an average of 9 statute miles.
Notable Features
The airport features three runways with different surface compositions: two PEM (Pavement with Exceptional Maintenance) and one ASP (Asphalt) runway. Runway lengths vary from 5,299 feet to 8,496 feet, providing flexibility for different aircraft categories. Wind data indicates consistent runway usability, with all three runways showing 100% favorable wind alignment and modest average crosswind conditions between 5.6 and 6.3 knots.
