Weather Briefing
VFRMary's Harbour Airport is currently reporting visual flight rules (VFR) conditions with clear skies and 9 SM visibility.
Wind Analysis
Winds are from the southwest (230°) at 11 knots with gusts to 17 knots. Runway 29 is favored with a 6-knot headwind and 10-knot crosswind component (gusting to 15 knots crosswind).
Visibility & Ceiling
Visibility is 9 SM. Skies are clear with unlimited ceiling.
Temperature & Moisture
Temperature is 1°C (34°F) with a dewpoint of -2°C. The narrow temperature-dewpoint spread suggests high humidity and potential for visibility restrictions, especially during cooling periods.
Forecast Outlook
The TAF forecast covers the next 7 hours. Conditions are expected to fluctuate between VFR and MVFR. VFR pilots should be prepared for deteriorating conditions. Expected weather includes: Light Showers SNRA, Mist, FCST, FCST. Winds are forecast to reach up to 20 knots during the period. Temporary MVFR conditions are forecast with Light Showers SNRA, Mist between 20:00Z and 03:00Z.
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.
