Flying Conditions

The airport experiences predominantly visual flight rules (VFR) conditions, with 81.6% of observations supporting clear weather operations. Wind patterns are characterized by northerly prevailing winds averaging 8.3 knots, though gusts up to 60 knots can occur, with calm conditions present 23.7% of the time. Temperature ranges from 0°C to 33°C, with an average of 19.7°C, creating generally stable flying conditions.

Notable Features

Situated at a significant elevation of 4,778 feet MSL, the airport presents density altitude considerations for aircraft performance. The airport features two runways: runway 03/21 at 3,471 feet and runway 17/35 at 9,506 feet, providing operational flexibility for various aircraft types. Both runways demonstrate 100% favorable wind alignment, with minimal average crosswind components of 3.4 and 3.3 knots respectively.

Approach Considerations

September, October, and January represent the most consistent VFR months, offering optimal flying conditions. Visibility averages 8.8 statute miles, with only 2.5% of observations showing conditions below 3 statute miles. Pilots should be prepared for occasional fog events, which occur approximately 6% of the time, potentially impacting approach and landing operations.
