Weather Briefing

VFR

Astoria Regional Airport is currently reporting visual flight rules (VFR) conditions with clear skies and 10 SM visibility.

Wind Analysis

Winds are from the north-northwest (330°) at 12 knots. Runway 31 is favored with a 11-knot headwind and 4-knot crosswind component.

Visibility & Ceiling

Visibility is 10 SM. Skies are clear with unlimited ceiling.

Temperature & Moisture

Temperature is 13°C (55°F) with a dewpoint of 9°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 fluctuate between VFR and MVFR. VFR pilots should be prepared for deteriorating conditions.

Pilot Recommendations

Conditions are favorable for visual flight. The forecast indicates conditions may deteriorate. Ensure you have fuel reserves and a viable alternate airport.

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

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.
