Weather Briefing
VFRHay River / Merlyn Carter Airport is currently reporting visual flight rules (VFR) conditions with broken clouds at 20,000 feet and 13 SM visibility. Note: This observation is 1.1 hours old and conditions may have changed.
Wind Analysis
Winds are from the east-southeast (120°) at 5 knots. Runway 14/32 is favored with a 5-knot headwind and 2-knot crosswind component.
Visibility & Ceiling
Visibility is 13 SM. The ceiling is 20000 feet AGL (broken), well above standard VFR minimums.
Temperature & Moisture
Temperature is 12°C (54°F) with a dewpoint of 11°C. The temperature-dewpoint spread is very narrow, indicating saturated or near-saturated air. Fog formation or low cloud development is likely.
Forecast Outlook
The TAF forecast covers the next 12 hours. The forecast shows a transition between VFR and IFR conditions. Pilots should monitor the forecast closely and have an alternate airport plan. Expected weather includes: Mist, FCST. Temporary IFR conditions are forecast with Mist between 09:00Z and 15:00Z. There is a 30% probability of MVFR conditions with Mist between 10:00Z and 14:00Z.
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. The forecast indicates conditions may deteriorate. Ensure you have fuel reserves and a viable alternate airport.

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.
