Weather Briefing

VFR

Yonago Kitaro Airport / JASDF Miho Air Base is currently reporting visual flight rules (VFR) conditions with clear skies and 10 miles or greater visibility.

Wind Analysis

Winds are from the east-northeast (70°) at 12 knots. Runway 07/25 is favored with a 12-knot headwind and 0-knot crosswind component.

Visibility & Ceiling

Visibility is unrestricted. Skies are clear with unlimited ceiling.

Temperature & Moisture

Temperature is 12°C (54°F) with a dewpoint of 12°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. Conditions are expected to remain VFR throughout the forecast period.

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 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.
