Weather Briefing

LIFR

Kumamoto Airport is currently reporting low IFR (LIFR) conditions with overcast skies at 100 feet and 4.3 km visibility.

Wind Analysis

Winds are from the south-southwest (210°) at 9 knots. Runway 25 is favored with a 7-knot headwind and 6-knot crosswind component.

Visibility & Ceiling

Visibility is reduced to 4.3 km. IFR conditions prevail and an instrument clearance is required for operations in controlled airspace. The ceiling is very low at 100 feet AGL (overcast), well below circling minimums at most airports.

Temperature & Moisture

Temperature is 25°C (77°F) with a dewpoint of 24°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. IFR conditions are expected to persist or develop. An instrument rating and IFR flight plan are recommended. Expected weather includes: Light Showers Rain, Thunderstorm Rain, Fog, Thunderstorm Rain, Mist. Temporary LIFR conditions are forecast with Thunderstorm Rain, Fog between 18:00Z and 00:00Z. Temporary LIFR conditions are forecast with Thunderstorm Rain, Mist between 00:00Z and 18:00Z. Temporary LIFR conditions are forecast with Thunderstorm Rain, Fog between 18:00Z and 00:00Z.

Pilot Recommendations

Current conditions require an instrument rating, IFR-equipped aircraft, and an IFR clearance. Check approach minimums carefully as conditions may be below CAT I ILS minimums. 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 Kumamoto Airport

Overview

Kumamoto Airport serves the Kumamoto Prefecture on Kyushu Island, Japan, functioning as a medium-sized regional airport. Located at 32.837299, 130.854996 with an elevation of 642 ft MSL, the airport provides essential transportation infrastructure for the surrounding metropolitan and rural areas. Its single runway 07/25 extends 9,840 feet with an asphalt surface, capable of handling a variety of aircraft types.

Flying Conditions

Weather conditions at Kumamoto Airport are predominantly favorable for visual flight, with 86.8% of observations reporting VFR conditions. The prevailing winds from the northeast (45°) average 5.2 knots, with occasional gusts up to 19 knots. Temperature ranges from -5°C to 32°C, with an average of 14°C, and visibility typically excellent at 10 statute miles. November, January, and October demonstrate the most consistent VFR weather patterns.

Notable Features

The airport's single runway 07/25 demonstrates excellent wind alignment, with 100% favorable wind conditions. Crosswinds average a modest 2.6 knots, suggesting relatively stable approach and departure environments. The airport's location on Kyushu Island likely introduces maritime influences that contribute to its predictable wind and visibility characteristics.

Approach Considerations

Runway 07/25's orientation and wind statistics indicate minimal wind-related complications for most operations. Pilots can expect consistent approach conditions, with only 3.5% of observations requiring instrument flight rules. The low occurrence of fog (3.9%) and rare instances of visibility below 3 statute miles suggest generally reliable visual approach capabilities.
