Weather Briefing

VFR

Hilo International Airport is currently reporting visual flight rules (VFR) conditions with broken clouds at 3,700 feet and 10 SM visibility.

Wind Analysis

Winds are from the northeast (50°) at 6 knots. Runway 03/21 is favored with a 6-knot headwind and 2-knot crosswind component.

Visibility & Ceiling

Visibility is 10 SM. The ceiling is 3700 feet AGL (broken), well above standard VFR minimums.

Temperature & Moisture

Temperature is 25°C (77°F) with a dewpoint of 21°C. The narrow temperature-dewpoint spread suggests high humidity and potential for visibility restrictions, especially during cooling periods.

Forecast Outlook

The TAF forecast covers the next 24 hours. Conditions are expected to remain VFR throughout the forecast period.

Pilot Recommendations

Conditions are favorable for visual flight.

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

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.
