Weather Briefing

VFR

Yonago Kitaro Airport / JASDF Miho Air Base is currently reporting visual flight rules (VFR) conditions with broken clouds at 3,000 feet and 10 miles or greater visibility.

Wind Analysis

Winds are from the south (180°) at 3 knots.

Visibility & Ceiling

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

Temperature & Moisture

Temperature is 23°C (73°F) with a dewpoint of 22°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. The forecast shows a transition between VFR and IFR conditions. Pilots should monitor the forecast closely and have an alternate airport plan. Expected weather includes: Mist. Temporary IFR conditions are forecast between 16:00Z and 21:00Z. Temporary IFR conditions are forecast with Mist between 21:00Z and 00:00Z. Temporary IFR conditions are forecast between 06:00Z and 15:00Z.

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. 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.

About Yonago Kitaro Airport / JASDF Miho Air Base

Yonago Kitaro Airport / JASDF Miho Air Base is a military facility. Civilian access may be restricted or require Prior Permission (PPR). Pilots should consult the JP AIP for current access procedures and restrictions.

Overview

Yonago Kitaro Airport, co-located with JASDF Miho Air Base, serves the western coastal region of Japan near Yonago city. The airport operates a single 8,202-foot asphalt runway (07/25) at a low elevation of 20 feet mean sea level, providing critical aviation infrastructure in the San'in region.

Flying Conditions

The airport experiences predominantly VFR conditions, with 87.7% of observations reporting clear weather suitable for visual flight. Temperature ranges from -1°C to 33°C, with an average of 13.3°C, indicating potential seasonal temperature variations. Wind patterns consistently blow from the south at an average of 8.2 knots, with maximum gusts up to 34 knots.

Notable Features

Located near the Sea of Japan coastline, the airport's geographic position influences its meteorological characteristics. The low elevation and coastal proximity suggest potential for marine layer development, though statistical data indicates minimal fog occurrence (0.8% of observations). The airport's dual civil and military usage provides operational flexibility for different aircraft types.

Approach Considerations

Runway 07/25 demonstrates highly favorable wind conditions, with 100% wind alignment and an average crosswind component of only 4.2 knots. November, December, and September represent the most consistent VFR months for flight operations. Pilots should anticipate stable approach conditions with typically excellent 10-statute-mile average visibility.
