About Central Wyoming Regional Airport

Overview

Central Wyoming Regional Airport serves the Riverton area as a medium-sized airport situated at a high elevation of 5525 feet MSL. Located in central Wyoming, the airport provides critical aviation infrastructure for the region, supporting various aircraft operations with two paved runways. Its strategic positioning offers essential transportation connectivity in a predominantly rural landscape.

Flying Conditions

Weather conditions at KRIW are predominantly favorable for visual flight rules (VFR), with 95.6% of observations supporting clear flying conditions. The airport experiences a significant temperature range from -16°C to 30°C, with an average temperature of 5.4°C. Westerly winds prevail at an average of 8.6 knots, with occasional gusts up to 39 knots, and calm conditions occurring 12.5% of the time.

Notable Features

The airport features two asphalt runways: Runway 01/19 at 4800 feet and Runway 10/28 at 8203 feet, providing substantial operational flexibility. Both runways demonstrate 100% favorable wind alignment, with average crosswind components of 5.8 knots and 5.1 knots respectively. The high elevation of 5525 feet MSL will require pilots to consider density altitude effects, particularly during warmer months.

Approach Considerations

Pilots can expect excellent visibility averaging 9.9 statute miles, with minimal instances of reduced visibility (only 0.2% below 3SM and 0.3% fog occurrences). October, January, and September represent the best months for VFR operations. The consistent wind patterns and long runways provide reliable approach options, with both runways offering straightforward wind-aligned landing opportunities.
