About Whidbey Island Naval Air Station (Ault Field)

Whidbey Island Naval Air Station (Ault Field) is a military facility. Civilian access may be restricted or require Prior Permission (PPR). Pilots should consult the US AIP for current access procedures and restrictions.

Overview

Whidbey Island Naval Air Station (Ault Field) is a medium-sized military airport located in Oak Harbor, Washington, serving naval aviation operations. Situated at an elevation of 47 feet MSL, the station provides critical infrastructure for maritime aviation activities in the Pacific Northwest region.

Flying Conditions

Weather conditions at KNUW are predominantly VFR, with 66.5% of observations showing clear conditions and only 8% of time experiencing low IFR or LIFR conditions. Prevailing winds are from the southeast at an average of 9.2 knots, with temperatures ranging from -3°C to 30°C. Visibility averages 9.1 statute miles, with fog present 10.3% of the time.

Notable Features

The airport features two substantial concrete runways: Runway 07/25 at 8,000 feet and Runway 14/32 at 8,001 feet. Both runways demonstrate 100% favorable wind coverage, with minimal average crosswind conditions of 6.5 knots for 07/25 and 3.9 knots for 14/32. The coastal location provides unique geographical positioning for naval aviation operations.

Approach Considerations

Pilots can expect consistently favorable wind conditions for both primary runways. September, October, and January offer the best VFR conditions, with wind patterns predominantly from the southeast. Maximum recorded wind speeds reach 46 knots, suggesting potential for challenging wind conditions during specific weather events.
