About Ellison Onizuka Kona International Airport at Keahole

Overview

Ellison Onizuka Kona International Airport serves the western coast of Hawaii's Big Island, located near Kailua-Kona at an elevation of 47 feet MSL. The airport provides critical air transportation infrastructure for the region, supporting both commercial and general aviation operations on its single runway 17/35, which extends 11,000 feet with an asphalt surface.

Flying Conditions

Pilots can expect predominantly excellent visual flying conditions, with 93.1% of observations reporting VFR weather. The airport experiences consistent southeast winds averaging 7 knots, with temperatures ranging from 18°C to 31°C and an average visibility of 9.9 statute miles. September, November, and January represent the most favorable months for visual flight operations.

Notable Features

The airport's geographic location on Hawaii's west coast introduces unique environmental considerations for pilots, including potential thermal variations and localized wind patterns. The single runway 17/35 demonstrates exceptional wind alignment, with 100% favorable wind conditions and an average crosswind component of only 4.6 knots, which contributes to predictable approach and departure environments.

Approach Considerations

With a remarkably stable wind profile predominantly from 135 degrees at an average of 7 knots, pilots can anticipate consistent runway 17/35 operations. Maximum recorded winds of 26 knots and only 5.3% calm conditions suggest that while wind variability exists, it remains within manageable parameters for most aircraft operations.
