Weather Briefing

MVFR

Niigata Airport is currently reporting marginal VFR (MVFR) conditions with overcast skies at 2,100 feet and 10 miles or greater visibility.

Wind Analysis

Winds are from the east-northeast (60°) at 5 knots. Runway 04/22 is favored with a 5-knot headwind and 2-knot crosswind component.

Visibility & Ceiling

Visibility is unrestricted. The ceiling is 2100 feet AGL (overcast), placing conditions in the MVFR category.

Temperature & Moisture

Temperature is 16°C (61°F) with a dewpoint of 13°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 30 hours. The forecast shows a transition between VFR and IFR conditions. Pilots should monitor the forecast closely and have an alternate airport plan. Temporary IFR conditions are forecast between 15:00Z and 22:00Z.

Pilot Recommendations

VFR pilots should exercise caution. Consider filing IFR if instrument rated, or postponing the flight if conditions are expected to deteriorate further. 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.
