About Lewiston Nez Perce County Airport
Overview
Lewiston Nez Perce County Airport serves the Lewiston region in the northwestern United States, situated at an elevation of 1,442 feet MSL. The airport features two asphalt runways: a primary runway 08/26 measuring 6,511 feet and a secondary runway 12/30 spanning 5,002 feet. As a medium-sized airport, it supports regional aviation operations in an area characterized by varied terrain.
Flying Conditions
Weather conditions at KLWS demonstrate significant variability, with Visual Flight Rules (VFR) prevailing 73% of the time. Temperature ranges from -5°C to 32°C, creating diverse flying environments throughout the year. Pilots can expect predominantly easterly winds averaging 6 knots, with calm conditions occurring 32.6% of the time and occasional gusts up to 34 knots.
Notable Features
The airport's geographic location presents unique meteorological characteristics, with reduced visibility occurring in 8.8% of observations and conditions below 3 statute miles happening 3.7% of the time. October, September, and November represent the most consistently favorable VFR months for aviation operations. Both runways demonstrate near-identical wind compatibility, with 100% favorable wind alignments and minimal average crosswind components.
Approach Considerations
Both runways 08/26 and 12/30 offer reliable wind alignments with minimal crosswind challenges, averaging just 3.4 and 3.6 knots respectively. Pilots should anticipate potential seasonal visibility variations and prepare accordingly, particularly during months with higher potential for reduced meteorological conditions. The airport's elevation and geographic positioning require standard mountain flying considerations and situational awareness.
