Weather Briefing

VFR

Ozuki Airfield is currently reporting visual flight rules (VFR) conditions with broken clouds at 3,000 feet and 9 km visibility. Note: This observation is 1214.8 hours old and conditions may have changed.

Wind Analysis

Winds are from the north (10°) at 7 knots. Runway 35 is favored with a 7-knot headwind and 2-knot crosswind component.

Visibility & Ceiling

Visibility is 9 km. The ceiling is 3000 feet AGL (broken), well above standard VFR minimums.

Temperature & Moisture

Temperature is 12°C (54°F) with a dewpoint of 11°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.
