Weather Briefing

VFR

Aupaluk Airport is currently reporting visual flight rules (VFR) conditions with few clouds at 4,500 feet and 15 SM visibility. Note: This observation is 57.5 hours old and conditions may have changed.

Wind Analysis

Winds are from the southwest (230°) at 10 knots with gusts to 16 knots. Runway 23 is favored with a 10-knot headwind and 0-knot crosswind component.

Visibility & Ceiling

Visibility is 15 SM. No ceiling exists. Cloud layers reported: few at 4,500 ft, few at 8,000 ft, few at 28,000 ft.

Temperature & Moisture

Temperature is -18°C (-0°F) with a dewpoint of -22°C. The narrow temperature-dewpoint spread suggests high humidity and potential for visibility restrictions, especially during cooling periods. 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.

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