About Astoria Regional Airport

Overview

Astoria Regional Airport serves the coastal region of northwestern Oregon, located near the Pacific Ocean and the Columbia River. As a medium-sized airport with two asphalt runways, it provides critical aviation infrastructure for the Astoria metropolitan area and surrounding regions. The airport sits at a low elevation of 15 feet above mean sea level, offering relatively straightforward terrain for aircraft operations.

Flying Conditions

Pilots can expect predominantly visual flight conditions, with 54.8% of observations reporting VFR and an additional 30.2% reporting marginal VFR conditions. Temperature ranges from -1°C to 31°C, with an average of 10.9°C, providing generally mild operating temperatures. Wind patterns are consistently from the south at an average of 7.7 knots, with occasional stronger gusts up to 33 knots and calm conditions occurring 12.7% of the time.

Notable Features

The airport features two parallel runways: Runway 08/26 at 5,796 feet and Runway 13/31 at 4,996 feet, both constructed of asphalt. Both runways demonstrate 100% favorable wind alignment, with modest average crosswind components of 4.9 and 5.3 knots respectively. Visibility averages 8 statute miles, with reduced visibility (below 3SM) occurring in 4.9% of observations and fog present in 1.9% of reports.

Approach Considerations

October, January, and December represent the best months for consistent VFR conditions. Both runways offer reliable wind alignment, making either suitable for most operations. Pilots should anticipate potential reduced visibility, particularly during winter months, with fog and low visibility conditions potentially impacting approach and landing planning. The consistently southern wind pattern provides predictable approach characteristics for most aircraft.
