Weather Briefing

MVFR

Amami Airport is currently reporting marginal VFR (MVFR) conditions with broken clouds at 2,900 feet and 10 miles or greater visibility.

Wind Analysis

Winds are from the west (280°) at 7 knots. Runway 21 is favored with a 2-knot headwind and 7-knot crosswind component.

Visibility & Ceiling

Visibility is unrestricted. The ceiling is 2900 feet AGL (broken), placing conditions in the MVFR category.

Temperature & Moisture

Temperature is 20°C (68°F) with a dewpoint of 19°C. The temperature-dewpoint spread is very narrow, indicating saturated or near-saturated air. Fog formation or low cloud development is likely.

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.
