Weather Briefing

VFR

Yamaguchi Ube Airport is currently reporting visual flight rules (VFR) conditions with overcast skies at 5,000 feet and 10 miles or greater visibility.

Wind Analysis

Winds are from the east (80°) at 15 knots. Runway 07/25 is favored with a 15-knot headwind and 3-knot crosswind component. Student pilots and low-time aviators should exercise caution.

Visibility & Ceiling

Visibility is unrestricted. The ceiling is 4700 feet AGL (broken), well above standard VFR minimums.

Temperature & Moisture

Temperature is 14°C (57°F) with a dewpoint of 13°C. The temperature-dewpoint spread is very narrow, indicating saturated or near-saturated air. Fog formation or low cloud development is likely.

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.

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