Weather Briefing

VFR

Sachs Harbour (David Nasogaluak Jr. Saaryuaq) Airport is currently reporting visual flight rules (VFR) conditions with few clouds at 4,000 feet and 15 SM visibility. Note: This observation is 162.1 hours old and conditions may have changed.

Wind Analysis

Winds are from the east-southeast (120°) at 7 knots. Runway 08T/26T is favored with a 5-knot headwind and 4-knot crosswind component.

Visibility & Ceiling

Visibility is 15 SM. No ceiling exists. Cloud layers reported: few at 4,000 ft, few at 11,000 ft.

Temperature & Moisture

Temperature is -19°C (-2°F) with a dewpoint of -21°C. The temperature-dewpoint spread is very narrow, indicating saturated or near-saturated air. Fog formation or low cloud development is likely. Temperatures are at or below freezing. Check for icing conditions and ensure aircraft anti-ice/de-ice systems are operational if required.

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.

This briefing is generated from real-time METAR and TAF data. Always verify with official sources before flight.
