Weather Briefing

LIFR

Aomori Airport is currently reporting low IFR (LIFR) conditions with overcast skies at 0 feet and 0.1 km visibility.

Wind Analysis

Winds are from the north-northeast (30°) at 3 knots.

Visibility & Ceiling

Visibility is severely reduced to 0.1 km, likely due to fog, mist, or precipitation. Special VFR or an IFR clearance may be required. No ceiling exists. Cloud layers reported: overcast at 0 ft.

Temperature & Moisture

Temperature is 16°C (61°F) with a dewpoint of 16°C. The temperature-dewpoint spread is very narrow, indicating saturated or near-saturated air. Fog formation or low cloud development is likely.

Forecast Outlook

The TAF forecast covers the next 30 hours. IFR conditions are expected to persist or develop. An instrument rating and IFR flight plan are recommended. Expected weather includes: Fog, Mist. Temporary LIFR conditions are forecast with Fog between 18:00Z and 22:00Z. Temporary LIFR conditions are forecast with Mist between 22:00Z and 00:00Z. Temporary LIFR conditions are forecast with Mist between 12:00Z and 15:00Z.

Pilot Recommendations

Current conditions require an instrument rating, IFR-equipped aircraft, and an IFR clearance. Check approach minimums carefully as conditions may be below CAT I ILS minimums. The narrow temperature-dewpoint spread creates risk of fog formation, particularly during evening and early morning hours.

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

Overview

Aomori Airport serves the Aomori Prefecture in northern Japan, positioned at an elevation of 664 feet MSL. The medium-sized airport provides critical transportation infrastructure for the Tohoku region, supporting both commercial and general aviation operations. Its strategic location near the northern tip of Honshu Island makes it an important regional aviation hub.

Flying Conditions

Weather conditions at Aomori Airport demonstrate significant variability, with Visual Flight Rules (VFR) predominating at 58.6% of observed conditions. Pilots should anticipate MVFR (14%), IFR (10.8%), and Low IFR (16.6%) conditions throughout the year. Temperature ranges from -11°C to 28°C, with an average of 5.1°C, suggesting potential for challenging winter operations and significant seasonal temperature fluctuations.

Notable Features

The airport features a single runway (06/24) extending 9,846 feet with an asphalt surface. Prevailing winds consistently blow from the southwest at 225°, with an average speed of 9.3 knots and occasional gusts up to 30 knots. Visibility typically remains excellent, averaging 10 statute miles with minimal fog occurrence (2% of observations) and no significant low-visibility events.

Approach Considerations

Runway 06/24 offers highly favorable wind alignment, with 100% wind compatibility and an average crosswind of just 3.5 knots. September, October, and November present the most consistently favorable VFR flying conditions. Pilots should prepare for potential winter challenges and leverage the runway's substantial length for safe operations across diverse weather scenarios.
