About Hay River / Merlyn Carter Airport

Overview

Hay River / Merlyn Carter Airport serves the Northwest Territories community of Hay River, located near the southern shore of Great Slave Lake. As a medium airport with two runways, it provides critical aviation infrastructure for regional transportation and supports diverse operational needs in a challenging northern environment.

Flying Conditions

Weather at CYHY demonstrates significant variability, with visual flight rules (VFR) conditions prevailing 65.2% of the time. Winter temperatures can drop to -39°C, while summers reach up to 28°C, creating substantial seasonal atmospheric changes. Prevailing westerly winds at an average of 7.8 knots and maximum gusts of 36 knots characterize the airport's wind profile.

Notable Features

Situated at 541 feet mean sea level, the airport features two distinct runways: a 4,001-foot commercial surface runway (05/23) and a 6,000-foot asphalt runway (14/32). Both runways demonstrate 100% favorable wind coverage, with relatively low average crosswind conditions of 5.7 and 4.1 knots respectively, enhancing operational flexibility.

Approach Considerations

Pilots can expect generally good visibility averaging 12.2 statute miles, with only 6% of observations showing reduced visibility below 3 miles. September, January, and December represent the most consistently favorable VFR months. Light fog occurs in approximately 1.7% of observations, suggesting minimal instrument meteorological conditions.
