Weather Briefing

VFR

Sundsvall-Härnösand Airport is currently reporting visual flight rules (VFR) conditions with overcast skies at 4,000 feet and 10 miles or greater visibility.

Wind Analysis

Winds are from the southeast (130°) at 14 knots. Runway 16/34 is favored with a 12-knot headwind and 7-knot crosswind component.

Visibility & Ceiling

Visibility is unrestricted. The ceiling is 4000 feet AGL (overcast), well above standard VFR minimums.

Temperature & Moisture

Temperature is 8°C (46°F) with a dewpoint of 5°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 3 hours. Conditions are expected to remain MVFR throughout the forecast period.

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.

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