About Kumejima Airport

Overview

Kumejima Airport serves the Kumejima Island region in Japan, located at coordinates 26.363445, 126.713840. The medium-sized airport sits at 23 feet above mean sea level and provides essential aviation infrastructure for the local area. Its single runway 03/21 spans 6,562 feet with an asphalt surface.

Flying Conditions

Weather observations reveal a predominantly VFR environment, with 35% VFR and 33.5% MVFR conditions. The airport experiences prevailing northeast winds at 45 degrees, averaging 15.9 knots with occasional gusts up to 34 knots. Seasonal temperature variations range from 13°C to 34°C, with an average of 23.2°C, supporting consistently stable flying conditions.

Notable Features

The airport's geographic positioning on Kumejima Island influences its wind patterns and visibility characteristics. Visibility averages 10 statute miles, with minimal instances of restricted visibility (fog occurs only 2% of the time). The runway alignment and local terrain suggest minimal obstructions or complex approach terrain.

Approach Considerations

Runway 03/21 demonstrates excellent wind alignment, with favorable wind conditions 100% of the time and an average crosswind of just 7 knots. Pilots can expect optimal VFR conditions particularly during September, October, and January. The consistent wind profile and high visibility make this a relatively straightforward approach environment.
