Weather Briefing

MVFR

Kagoshima Airport is currently reporting marginal VFR (MVFR) conditions with broken clouds at 2,000 feet and 10 miles or greater visibility.

Wind Analysis

Winds are calm, presenting no crosswind concerns for any runway.

Visibility & Ceiling

Visibility is unrestricted. The ceiling is 2000 feet AGL (broken), placing conditions in the MVFR category.

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.

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 12:00Z and 15:00Z. Temporary IFR conditions are forecast with Mist between 15:00Z and 18:00Z. Temporary IFR conditions are forecast between 18:00Z and 00:00Z.

Pilot Recommendations

VFR pilots should exercise caution. Consider filing IFR if instrument rated, or postponing the flight if conditions are expected to deteriorate further. 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 Kagoshima Airport

Overview

Kagoshima Airport serves as a critical transportation hub for southern Kyushu, located in Japan's Kagoshima Prefecture. Positioned at an elevation of 906 feet mean sea level, the airport supports commercial, cargo, and general aviation operations with its substantial single runway measuring 9,840 feet in length.

Flying Conditions

Situated at 31.803400°N latitude, Kagoshima Airport experiences typical maritime subtropical climate conditions characteristic of southern Japan. Pilots should anticipate potential seasonal wind variations and precipitation patterns that can influence approach and departure procedures, particularly during summer typhoon seasons and winter monsoon periods.

Notable Features

The airport's terrain is influenced by its proximity to volcanic regions, with potential for unique meteorological interactions due to local geographic conditions. The single runway (16/34) is constructed of asphalt, providing a robust surface for diverse aircraft operations at this elevation.

Approach Considerations

Given the runway's 16/34 orientation, prevailing wind patterns will significantly influence approach and landing strategies. Pilots should carefully assess current meteorological conditions and utilize standard instrument approach procedures, maintaining awareness of the airport's 906-foot elevation when calculating performance parameters.
