About Hilo International Airport

Overview

Hilo International Airport serves the eastern side of Hawaii's Big Island, located in the city of Hilo. As a medium-sized airport with two substantial runways, it provides critical aviation infrastructure for the region, supporting both commercial and general aviation operations. The airport sits at a low elevation of 38 feet mean sea level, offering relatively straightforward terrain interaction.

Flying Conditions

Weather conditions at Hilo are predominantly visual flight rules (VFR), with 74.3% of observations supporting clear flying conditions. Southwest winds averaging 5.9 knots characterize the airport's wind profile, with occasional gusts up to 20 knots. Temperature remains consistently moderate, ranging from 16°C to 31°C, with an average of 22.9°C, providing stable atmospheric conditions for most of the year.

Notable Features

The airport features two parallel asphalt runways: a 5,600-foot runway (03/21) and a longer 9,800-foot runway (08/26). Both runways demonstrate excellent wind alignment, with 100% favorable wind coverage and minimal average crosswind components (3.6kt and 3.1kt respectively). The geographical location near the Pacific Ocean influences local meteorological conditions, contributing to the airport's consistent visibility averaging 9.2 statute miles.

Approach Considerations

Pilots can expect optimal flying conditions during December, October, and September, which represent the best VFR months. The runways offer flexible approach options with consistent wind patterns. While instrument meteorological conditions are rare (IFR/LIFR conditions represent only 2.8% of observations), pilots should still prepare for potential variability, particularly during less favorable months.
