Weather Briefing

VFR

Aupaluk Airport is currently reporting visual flight rules (VFR) conditions with clear skies. Note: This observation is 85.6 hours old and conditions may have changed.

Wind Analysis

Winds are from the north-northwest (340°) at 8 knots. Runway 04/22 is favored with a 4-knot headwind and 7-knot crosswind component.

Visibility & Ceiling

Skies are clear with unlimited ceiling.

Temperature & Moisture

Temperature is -8°C (18°F) with a dewpoint of -9°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.
