Weather Briefing

VFR

Seinäjoki Airport is currently reporting visual flight rules (VFR) conditions with scattered clouds at 2,100 feet and 10 miles or greater visibility.

Wind Analysis

Winds are from the southwest (230°) at 11 knots. Runway 14/32 is favored with a 0-knot headwind and 11-knot crosswind component.

Visibility & Ceiling

Visibility is unrestricted. No ceiling exists. Cloud layers reported: scattered at 2,100 ft, scattered at 4,000 ft.

Temperature & Moisture

Temperature is 15°C (59°F) with a dewpoint of 11°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 9 hours. Conditions are expected to fluctuate between VFR and MVFR. VFR pilots should be prepared for deteriorating conditions. There is a 40% probability of VFR conditions between 11:00Z and 14:00Z.

Pilot Recommendations

Conditions are favorable for visual flight. The forecast indicates conditions may deteriorate. Ensure you have fuel reserves and a viable alternate airport.

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