Weather Briefing

MVFR

Amami Airport is currently reporting marginal VFR (MVFR) conditions with few clouds at 1,500 feet and 8 km visibility.

Wind Analysis

Winds are from the south-southwest (200°) at 5 knots. Runway 21 is favored with a 5-knot headwind and 1-knot crosswind component.

Visibility & Ceiling

Visibility is 8 km, below VFR minimums in some airspace classifications. Check local requirements before departing VFR. No ceiling exists. Cloud layers reported: few at 1,500 ft.

Temperature & Moisture

Temperature is 31°C (88°F) with a dewpoint of 28°C. The narrow temperature-dewpoint spread suggests high humidity and potential for visibility restrictions, especially during cooling periods. High temperatures at this elevation may result in significant density altitude effects. Pilots should calculate density altitude and adjust performance expectations accordingly.

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.

This briefing is generated from real-time METAR and TAF data. Always verify with official sources before flight.

About Amami Airport

Overview

Amami Airport serves the Amami Islands region in southern Japan, located at 28.430599, 129.712997 with an elevation of 27 feet MSL. As a medium-sized airport, it provides critical transportation infrastructure for this island locale, supporting regional and potentially inter-island aviation operations.

Flying Conditions

The airport experiences predominantly VFR conditions, with 88.9% of observations indicating clear flying weather. Prevailing winds from the north at an average of 8.9 knots create generally stable atmospheric conditions, with maximum recorded winds reaching 30 knots. Temperature variations range from 9°C to 33°C, with an average of 21.7°C, suggesting mild and consistent climate characteristics.

Notable Features

The single runway 03/21 spans 6,560 feet with an asphalt surface, positioned to take advantage of the region's consistent wind patterns. Its geographic position in the Amami Islands introduces potential maritime weather influences, with extremely low occurrence of fog (0.1% of observations) and consistently high visibility averages around 10 statute miles.

Approach Considerations

Runway 03/21 demonstrates favorable wind alignment 100% of the time, with an average crosswind component of only 5.5 knots. Pilots can expect optimal VFR conditions particularly during January, September, and December. The low crosswind and high percentage of clear flying conditions make this a relatively straightforward airport for approach and landing.
