Weather Briefing
VFRYonaguni Airport is currently reporting visual flight rules (VFR) conditions with few clouds at 2,000 feet and 10 miles or greater visibility.
Wind Analysis
Winds are from the south-southwest (210°) at 8 knots. Runway 26 is favored with a 5-knot headwind and 6-knot crosswind component.
Visibility & Ceiling
Visibility is unrestricted. No ceiling exists. Cloud layers reported: few at 2,000 ft.
Temperature & Moisture
Temperature is 28°C (82°F) with a dewpoint of 25°C. The narrow temperature-dewpoint spread suggests high humidity and potential for visibility restrictions, especially during cooling periods.
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.

About Yonaguni Airport
Overview
Yonaguni Airport serves the remote Yonaguni Island, located at the westernmost point of Japan. Situated at 70 feet above mean sea level, this medium-sized airport provides critical transportation infrastructure for the island's 1,700 residents and supports regional connectivity in the Ryukyu Islands.
Flying Conditions
Meteorological data indicates predominantly favorable visual flight conditions, with 68.3% of observations supporting VFR operations. Wind patterns are consistently from the northeast at an average of 15.4 knots, with September, November, and January presenting the most stable flying conditions. Temperature ranges from 12°C to 34°C, with an average of 23.7°C, offering generally mild operating environments.
Notable Features
The airport features a single 4,920-foot asphalted runway (08/26) positioned to maximize wind alignment. Its geographic location at 24.467298, 122.979827 places it in a maritime environment with potential for rapidly changing wind conditions, as evidenced by occasional wind gusts reaching up to 46 knots. Proximity to the ocean likely introduces complex local wind dynamics for pilots to anticipate.
Approach Considerations
Runway 08/26 demonstrates excellent wind compatibility, with 100% favorable wind conditions and an average crosswind of 11 knots. Pilots should expect consistent northeast winds and prepare for potential moderate crosswind components. The high percentage of VFR conditions (68.3%) suggests reliable visual approach opportunities throughout the year.
