About Walla Walla Regional Airport

Overview

Walla Walla Regional Airport serves the southeastern Washington region as a medium-sized airport located at an elevation of 1,194 feet MSL. Situated at coordinates 46.094898, -118.288002, the airport provides critical aviation infrastructure for the Walla Walla metropolitan area, supporting general aviation, potential regional commercial operations, and local transportation needs.

Flying Conditions

Weather conditions at KALW demonstrate significant variability, with VFR conditions predominating at 74.7% of observations. Pilots can expect moderate wind patterns averaging 6.9 knots from the south, with temperature ranges from -4°C to 31°C. Visibility typically remains excellent at 9 statute miles, though fog occurs in 11.1% of observations and conditions can drop below 3 miles in 4% of reports.

Notable Features

The airport features three runways with diverse orientations, offering flexibility for different wind conditions. Runway 02/20 is the longest at 6,526 feet with an asphalt surface, while runways 07/25 and 16/34 are 4,486 and 5,948 feet respectively, both with a pavement/mix surface. All runways demonstrate 100% favorable wind alignment, with modest average crosswind components ranging from 3.2 to 4.6 knots.

Approach Considerations

Seasonal considerations suggest September, October, and December offer the most consistent VFR conditions for approach and departure. With prevailing southerly winds and multiple runway options, pilots have good operational flexibility. The airport's moderate elevation and relatively stable wind patterns contribute to predictable approach environments across all three runways.
